Brass - Complex Copper Nickel Zinc Alloys

On this page is a table of Brass - Complex Copper Nickel Zinc Alloys specifications, its data comes from many references and is accumulated here.

The Table below is as good a reference as to what brass can be found in various products and will provide a valuable guide as to the type of metals that are contained within various Copper alloys.

It lists BS, European, CEN & ISO identification, listing Common British Description, a brief remark on use & its availability.
