Brass - Basic Copper Zinc & Lead Alloys

Powered by Spearhead Software Labs Joomla Facebook Like Button

On this page is a table of Brass - Basic Copper Zinc & Lead 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 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.
