Cast

This group of alloys is typically found in plumbing applications. The most widely used alloy in this family is C84400 semi-leaded red brass, known for its reasonable cost with good machining and casting properties. The lead content ensures pressure tightness. Red brass is also used for low-cost bearing materials under low loads.
