| 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. |
| C92200 | Leaded Tin Bronze | 88-6-1-4; Navy "M" Bronze; Steam Bronze |
Typically used for corrosion resistant mechanical parts exposed to high pressures and temperatures up to 550°F |
| C86500 | Manganese Bronze | Manganese Bronze (65k psi) | The most popular alloy for propeller components and other parts in contact with salt and fresh water. |
| C90300 | Tin Bronze | 88-8-0-4; Tin Bronze; Navy "G" Bronze |
Used for parts where high wear resistance is desired such as bearings, gears, and piston rings. Can be used in pressure-retaining applications at temperatures up to 500°F |
| C87600 | Silicon Bronze | Low Zinc Silicon Brass | Typically used for valve stems. |
| C86300 | Manganese Bronze | Manganese Bronze (110k psi); High-Strength Yellow Brass |
Used for extra heavy-duty mechanical parts in non-corrosive atmospheres. |
