Types of Scrap Metals
Magnesium Scrap Metal
Sources of Magnesium include magnesium-base scrap which can be generally categorized into four types. Type I is a high-grade scrap, which include materials, such as runners, gates, and drippings from die casting operations, which is uncontaminated with oils. Types II, III, and IV are lower grade materials in which type II is oil-contaminated scrap, type III is dross from magnesium-processing operations, and type IV is fines and chips.
Copper Scrap Metal
No. 1 Heavy Scrap Copper which consists of clean unalloyed copper solids and must be uncoated. It may also include copper clippings, punchings, bus bars, commutator segments, clean copper pipe or tubing and copper wire over 1/16th thick but free of brittle or burnt wire.
No. 2 Scrap Copper which consists of clean unalloyed copper solids. May also include clean, oxidized or coated copper clippings, bus bars, punchings, clean oxidized copper tubing or pipe free of excessive solder and light gauze clean. It should be free of exuberant oxidation, ash, scale or brittle burnt wire.
