Copper-based alloys (1% primary nickel use)
[Back to "Production Scrap"]
[Back to "Nickel-based Alloys"]
Similar considerations apply as to nickel-based alloys but copper-based nickel alloys are fewer, less complex
and easier to segregate. In the commonly used alloys -- cupronickel 90/10 and 75/25, nickel silver, Monel --
it is feasible to make the alloys 100% out of recycled secondary alloy provided the material is clean and
well segregated.
Mixed copper-based nickel containing scrap can be remelted using primary metal additions to adjust the
chemistry. Some nickel-containing copper-based alloys are used for special blends for certain nickel- and
copper-containing steel grades. Some may become mixed with copper and be used as a raw material for general
purpose brass production.
