Copper components. The best known traditional types are bronze, where tin is a significant addition, and brass, using zinc instead. Both these are imprecise terms, both having been commonly referred to as lattens in the past. Today the term copper alloy tends to be substituted, especially by museums.

The similarity in external appearance of the various alloys, along with the different combinations of elements used when making each alloy, can lead to confusion when categorizing the different compositions. There are as many as 400 different copper and copper alloy compositions loosely grouped into the categories: copper, high copper alloy, brasses, bronzes, copper nickels, copper–nickel–zinc (nickel silver), leaded copper, and special alloys. The following table lists the principal alloying element for four of the more common types used in modern industry, along with the name for each type. Historical types, such as those that characterise the Bronze Age, are vaguer as the mixtures were generally variable.

The global copper industry is in crisis

Copper industry in crisis, new areas pursued

The global copper industry is in crisis – traditional orebodies are becoming depleted and the commodity market has depressed the price of copper to such an extent that mining companies cannot afford to invest in expansion or new equipment, says foundry and engineering company Thos Begbie group executive Edwin Dreyer. “Lower ore values mean additional tonnage must be mined to obtain the same yield as before, which…
