Brass alloys

It is a copper-zinc alloy whose copper content can vary from 57 to 63% and zinc and other elements are added to obtain specific properties. Over the years, Almag has collected one of the widest ranges of alloys in the industry. Dozens of research projects are still on-going today, making our offer more complete every day.

Characteristics

Among all the possible alloys of copper and zinc, brasses occupy a marginal role in the phase diagram. More precisely, copper alloys of technological interest have copper content ranging from 57% to 70%. The α phase has good cold workability while the β phase has good hot workability.
