C330 Brass Specifications

Brass is a metal primarily composed of copper and zinc. A rust-free mineral, it resists corrosion and polishes to a shiny color close to that of gold. Brass is easy to solder and easy to work on when cold. Common uses for brass include piping and wiring. C330 is a particular formulation of brass whose easy workability properties and inclusion of a small amount of lead make it ideal for tubing. In fact, most brass fire poles in firehouses are made of C330 brass.

Strength And Hardness
- A bar of C330 brass has a yield strength of 50,000 lbs. per square inch (psi). ("Yield strength" refers to the amount of tensile pressure needed to begin deforming a material.) It will ultimately snap at its ultimate tensile strength of 65,300 psi, and it will elongate 32 percent before it snaps. C330 brass has a Rockwell hardness number of B70.
Chemical Composition
- C330 brass contains between 65 and 68 percent copper, and zinc makes up 33.5 percent of the metal. It contains less than 1 percent of each of its remaining essential components --- iron and lead. The lead content provides C330's superior capacity for machining.
Fabrication And Uses
- The most common means to fabricate C330 brass include forming and bending, machining, piercing and punching. Common applications include power and pump cylinders and their liners, primers, many brass plumbing accessories and electrical wiring.
