In the handling of wet, sticky ores such as encountered in tropical areas having distinct dry and rainy seasons, the crushing plant is a section of the mill which must be planned very carefully.

Free-machining copper has an addition of around 0.5% of sulfur or tellurium which raises the machinability rating of copper from a value of 20 to 90 (based on a scale of 100 headed by free-cutting brass, UNS C36000).

The copper section is administered by the Copper Development Association, but it is not a specification. It eliminates the limitations and conflicts of alloy designations previously used and at the same time provides a workable method for the identification marking of mill and foundry products.

Copper Group. Copper was one of the first metals to be worked into implements and the first metal to be smelted from ores. Its excellent ductility and high conductivity assure its use in modern society.
