Scrap metal pricing comes down to one foundational distinction: iron content. Whether a material contains iron or not controls how it gets graded, which buyers will take it, and what they will pay. For manufacturers generating scrap daily, that distinction separates a managed revenue stream from a systematic undercharge on every load.
This guide covers both categories, their specific price differences, and the sorting decisions that determine how much value your facility actually captures.
The One Difference That Drives Every Pricing Decision
Ferrous metals contain iron. Non-ferrous metals contain no iron at all. That two-word distinction drives downstream consequences for processing method, buyer category, and settlement price.
Iron content gives ferrous metals three properties relevant to any scrap program. Most ferrous metals are magnetic, which enables fast mechanical separation at processing facilities. Iron also makes these materials susceptible to rust and oxidation, which affects grade. Finally, ferrous scrap exists in very high global volume. That supply keeps per-unit prices lower and more stable than most non-ferrous alternatives.
Non-ferrous metals lack iron, so they resist corrosion and carry higher per-pound values. They also respond more quickly to global market shifts than ferrous materials do. A 5% move in copper prices changes your next settlement figure noticeably. The same percentage move in prepared steel scrap barely changes a monthly total. Knowing which materials your facility generates, and keeping them separated, is the foundation of any serious scrap revenue program.
Ferrous Scrap: Steel, Iron, and What You Get for It
The U.S. steel industry consumed approximately 57 million tons of iron and steel scrap in 2025, according to U.S. Geological Survey data. Electric arc furnaces (EAFs), which account for roughly 70% of domestic steel production according to the Steel Manufacturers Association, use ferrous scrap as their primary feedstock. Demand for quality ferrous scrap is structural and growing. So is the competition for well-prepared, high-grade material.
That high volume keeps ferrous prices stable but modest. Prepared steel scrap trades between $100 and $165 per ton, depending on grade, preparation, and regional market conditions. Heavy melting steel and #1 prepared steel sit at the upper end of that range. Light iron, sheet clips, and unprepared mixed material fall toward the lower end. The grade your material receives, and whether it arrives at the buyer prepared or bulk, directly determines your settlement figure.
Common Ferrous Scrap Types in Manufacturing
Manufacturing facilities generate several distinct grades of ferrous scrap:
- Carbon steel and mild steel: structural frames, weldments, tooling fixtures, and fabricated components. The most common and highest-volume ferrous material in most facilities.
- Cast iron: machinery housings, compressor bodies, pipe fittings, and motor mounts. Dense, predictable in pricing, and identifiable by weight and appearance.
- Alloy steel: dies, molds, wear plates, and hardened tooling. Specific alloy content determines which buyers can use the material, so accurate identification matters at separation.
- 304 stainless steel: food processing equipment, tanks, and structural fabrications. Non-magnetic, unlike carbon steel, which creates identification complexity in mixed loads.
Non-Ferrous Scrap: Higher Value, More Volatility
Non-ferrous metals represent the higher-value portion of your scrap stream. Copper trades between $2.40 and $4.50 per pound for clean, graded material, based on 2025 benchmark pricing from industry market data. That places copper roughly 30 to 40 times more valuable per pound than standard steel scrap. Aluminum ranges from $0.55 to $0.90 per pound for clean material. Brass trades between $1.25 and $2.20 per pound, depending on alloy composition and contamination level.
The premium reflects real and durable physical properties. Copper conducts electricity better than most commercially viable alternatives, making it the dominant material for power grid infrastructure, electric vehicle wiring, and data center cabling. Aluminum’s combination of light weight and full recyclability drives consistent demand from automotive and aerospace manufacturers. Brass carries copper’s conductivity alongside improved machinability, making it the standard material in precision valves, hydraulic fittings, and bearing housings.
Non-ferrous prices also move quickly. Copper can shift by several hundred dollars per metric ton within a single month, depending on global demand signals and trade conditions. That volatility makes grade verification and direct buyer relationships more important for non-ferrous settlement than they are for ferrous. A facility selling copper to a single local buyer without benchmarking against current market rates is almost certainly leaving value behind.
Common Non-Ferrous Scrap Types in Manufacturing
The non-ferrous materials most frequently generated in manufacturing environments include:
- Aluminum extrusions, sheet, and machining chips: common in automotive, aerospace, and consumer goods production. The specific alloy grade, such as 6061 versus 6063 versus 2024, carries different pricing at settlement.
- Copper bus bar, wire, and machining turnings: generated in electrical, HVAC manufacturing, and precision machining. Cleanliness and insulation removal are the primary pricing variables.
- Brass rod, castings, and fittings: standard output from valve, plumbing component, and bearing manufacturing operations.
- 316 stainless steel: contains molybdenum and commands a meaningful premium over 304 stainless. These two grades look identical. They require XRF testing or other instrumental analysis to separate accurately. Shipping 316 at 304 pricing is a direct, avoidable revenue loss on every load.
- Lead and zinc: generated in battery manufacturing, galvanizing operations, and die casting facilities.
The Sorting Problem That Costs Manufacturers Thousands Each Year
The most common revenue loss in manufacturing scrap programs comes from mixed or unsorted loads. When ferrous and non-ferrous materials ship together in the same container, the entire load is priced at the lowest-grade material present. A bin containing steel offcuts, copper pipe ends, and aluminum extrusion trim does not settle at three separate prices. It settles at the steel rate.
According to market data published by Okon Recycling, unsorted materials sell for 20 to 40 percent less than well-separated loads. The gap is sharper for copper. Clean copper wire without insulation commands approximately $3.20 per pound. The same copper with insulation attached falls to around $1.70 per pound. The processing cost comes directly out of your settlement.
The math compounds over volume. A facility generating 2,000 pounds of copper-bearing scrap per month, shipping it in mixed loads at $1.70 per pound instead of $3.20 per pound, leaves roughly $36,000 per year unrealized from that single material stream. That figure does not account for any other non-ferrous materials being undervalued in the same loads.
Misidentified alloys create a separate and less visible problem. A batch of 316 stainless sold at 304 stainless pricing recovers less than actual market value on every load. Bare bright copper shipped as #2 copper loses several cents per pound at every settlement. These misidentifications happen consistently without specialized testing, and they always favor the buyer.
This is a pattern Millbridge Metals sees regularly. Mixed ferrous and non-ferrous loads are among the most common reasons manufacturing operations receive less than market value for their scrap. The fix is structural: it starts with a material audit and a sorting protocol, not a different price negotiation with the same buyer.
How to Identify Your Metals on the Floor
Manufacturers do not need laboratory equipment to build a workable sorting protocol. A few practical steps separate the bulk of ferrous from non-ferrous material at the point of generation.
The magnet test is the first and fastest step. Most ferrous metals attract a strong magnet. Most non-ferrous metals, including copper, aluminum, brass, and lead, do not. One important exception applies to stainless steel. The 410 and 430 series stainless grades are magnetic. The 304 and 316 grades are not. Magnetism alone does not reliably sort all stainless, so a secondary check is necessary for facilities generating stainless steel scrap.
Color and density provide that secondary check. Copper is a distinctive reddish-brown. Brass is yellow-gold. Aluminum is lighter silver and noticeably less dense than steel of the same size. Lead is dull gray and unusually heavy for its volume. Carbon steel and cast iron share a similar dark gray appearance and are hard to distinguish visually. A spark test against a bench grinder wheel can help differentiate these: high-carbon steel produces bright white, long sparks with many branch patterns. Cast iron produces shorter, darker sparks with fewer branches.
For facilities generating significant volumes of high-value alloys, a portable XRF (X-ray fluorescence) analyzer provides on-the-spot composition readings in under five seconds. XRF is the only practical field method for separating 316 stainless from 304 stainless, or for confirming copper alloy grades without destructive testing. Some scrap management programs include this analysis as part of the service, removing the capital cost from the manufacturer.
The single most effective operational change for most facilities is dedicated container placement at the point of generation. Separate, labeled bins for ferrous, copper, aluminum, brass, and stainless steel, positioned where scrap is actually produced on the floor, prevent mixing before it starts. The cost of additional containers is trivial against the per-ton revenue difference between sorted and unsorted loads.
Why Mill Placement Determines Your Final Return
Correct sorting is necessary, but it is not the whole equation. Getting material to the buyer who values it most, at the price your specific grade commands, is where full value is realized.
Different mills pay meaningfully different prices for the same general material description. A regional steel mill might pay $120 per ton for heavy melting steel. A mill purchasing for automotive-grade flat-rolled sheet production might pay $155 per ton for the same general category if the chemistry and preparation qualify. Non-ferrous buyers, copper refiners, and aluminum smelters each run their own specifications. Meeting those specifications earns a premium over the standard rate for an undifferentiated category.
Manufacturers selling to a single local yard have no visibility into this range. They accept one price and assume it reflects the market. In practice, it reflects the yard’s margin requirements, not the full range of what competing buyers would pay for that material today.
A mill brokerage relationship gives your material access to multiple competing buyers. When your copper qualifies for a specific grade, it moves to the buyer paying the most for that grade in the current market. When your ferrous material qualifies as prime, it goes to the mill that needs prime, not the nearest yard that accepts everything at a blended rate. That placement discipline, applied consistently on every load, converts scrap from a minor line item into a predictable and optimized revenue stream.
What a Scrap Management Partner Does That a Local Yard Cannot
A local scrap yard buys your material at a price that works for the yard. A scrap management partner works on your side of the transaction. Millbridge Metals earns better margins by getting you better returns, so the interests are aligned from the start.
Millbridge operates as a third-party scrap management broker for manufacturers, fabricators, demolition contractors, and commercial facilities across Ohio, Kentucky, Tennessee, Georgia, Indiana, and Illinois. Every engagement begins with a material audit. The audit identifies what your facility generates, how it is currently sorted, where grading errors are costing money, and which material streams would benefit most from placement changes. That step alone regularly identifies thousands of dollars in annual recoverable revenue for mid-sized manufacturing operations.
The industrial and commercial recycling program then covers container sizing and placement, scheduled hauling, certified weight verification on calibrated scales, and transparent settlement reports with per-load detail on weight, grade, and pricing. A dedicated project manager coordinates logistics across your entire operation. Mill relationships across North America connect your material grades with the buyers paying the most for them in the current market, not just the most geographically convenient option.
If your current scrap program is not benchmarked against market rates across multiple buyers, there is room to improve the return. The assessment is free, and the findings are specific to your operation.
