Arsenical bronze Wikipedia

Arsenical bronze is an alloy in which arsenic, as opposed to or in addition to tin or other constituent metals, is added to copper to make bronze.The use of arsenic with copper, either as the secondary constituent or with another component such as tin, results in a stronger final product and better casting behavior.. Copper ore is often naturally contaminated with arsenic; hence, the term
