Brass C230 (red brass) is an 85/15 copper-zinc brass with excellent corrosion resistance, excellent cold workability, and excellent brazing and soldering. It is suited to plumbing fittings, hardware, and fasteners.
C230 (red brass, CW502L, CuZn15) is about 85% copper and 15% zinc. Its high copper content gives excellent corrosion resistance and dezincification resistance, conductivity of about 32–37% IACS, and excellent cold workability, with excellent brazing and soldering.
Brass C230 is commonly used for fire hose couplings, plumbing fittings, cold-formed hardware, and dezincification-resistant fasteners.
