CDA Spec Class Also Known As Description
C84400 Leaded Semi-Red Brass 81-3-7-9;
Valve Metal
The most popular copper alloy in the US for plumbing markets. Good machinability and pressure tightness.
C83600 Leaded Red Brass 85-5-5-5;
Ounce Metal;
Composition Metal
The most commonly cast copper alloy worldwide. Primarily used in plumbing applications due to it's corrosion resistance and pressure tightness.
C87500 Silicon Brass 82-4-14;
Tombasil
Used in applications where high strength and corrosion resistance are required. Has a good castability as well.
C99500 Special Alloy NDZ-S Special Nondezincification alloy which resists the leakage of zinc in certain types of water. This variant also has a high yield strength.
C89836 Bismuth Bronze Bismuth Tin Bronze Generally used as an alternative to red brasses for lead free plumbing applications.
