The hardness of brass is bigger than Aluminium alloys but smaller than cast iron and cast steel. So it is easy to stick cutting tools during machining. Usually the high hardness alloy steel could be used as the materials of cutting tools for brass machining. Casting brass has higher mechanical properties than bronze, but the price is lower than bronze. Cast brass is often used for general purpose bearing bushes, bushings, gears and other wear-resistant parts and valves and other corrosion-resistant parts. Brass has strong wear resistance. Brass is often used to make valves, water pipes, connecting pipes for internal and external air conditioners, and radiators.
