About CW603N Free Machining Brass

CW603N 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. CW603N 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. CW603N Brass can be precision machined easily. Although ductile in its softened state, CW603N Brass is a strong material to work with and maintains its strength even under some of the most demanding conditions. CW603N Brass forms a thin protective patina, which, unlike steel and iron, will not rust when exposed to the atmosphere. As a high-density material, CW603N Brass is ideal for heavy industrial parts. CW603N Brass is also valued for its high polished finish. CW603N Brass is available in Rounds, Flats, Squares, Hexagons, Shapes and Hollows.
