Copper-zinc alloy pipe and tube for general engineering & plumbing.
Material Overview
Brass pipe and tube, a copper-zinc alloy, offers a strong balance of machinability, corrosion resistance and strength — widely used in plumbing fittings, decorative fixtures, and general engineering applications.
Grades & Standards
Available grades and the international standards commonly applied to brass pipes & tubes.
Technical Data
Cartridge Brass (C26000) is the primary tube-forming brass grade, with Yellow Brass (C27000) also commonly supplied.
