Red Brass
Brass is any alloy of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties.
1. In comparison, bronze is principally an alloy of copper and tin.
2. Despite this distinction some types of brasses are called bronzes and vice-versa.
3. Brass is a substitutional alloy.
The presence in brass of some other elements such as lead is often required to improve machinability so such scrap is frequently acceptable.
Besides the common free-machining brasses, there are many others made for special purposes with properties modified to
give extra strength, hardness, corrosion resistance or other attributes, so strict segregation of scrap is essential.
Brass scrap arising from machining operations can be economically re-melted but should be substantially free from excess lubricant, especially those including organic compounds that cause unacceptable fume during re-melting.
