Brass CDA 360 alloy has the highest machinability of all copper alloys, extremely popular for parts that require strength, weight, or a polished surface finish. Available in round, square, hex, and tube stock at low costs, Brass 360 has a very wide range of applications, and is ideal for industrial and electronic industries. Unlike steel, 360 also forms a thin protective patina that does not rust.
Brass 360 has the highest machinability of all copper and brass alloys. It has a machining cost factor of 0.6 when compared to steel 12L14 It has fair hot forming properties and is not ideal for cold forming, welding, soldering, and brazing. Brass 360 can be forged and annealed.
Due to brass 360's excellent machinability and the high return value of scrap, the net cost of machining brass is competitive with steel.
