About CZ124 Free Machining Brass

CZ124 Free machining brass, produced from a combination of copper and zinc, has the highest machinability of all copper alloys, and is the standard against which all the others are compared to. CZ124 Brass, known for its strength and resistance to corrosion with properties closely resembling that of steel, is one of the most popular copper alloys used today. CZ124 Brass can be precision machined easily. Although ductile in its softened state, CZ124 Brass is a strong material to work with and maintains its strength even under some of the most demanding conditions. CZ124 Brass forms a thin protective patina, which, unlike steel and iron, will not rust when exposed to the atmosphere. As a high-density material, CZ124 Brass is ideal for heavy industrial parts. CZ124 Brass is also valued for its high polished finish. CZ124 Brass is available in Rounds, Flats, Squares, Hexagons, Shapes and Hollows.
