Brass Extrusion and Components
Leaded brass is a copper-zinc alloy containing lead additives (typically 1-3.5%) specifically designed to enhance machinability, strength, and corrosion resistance. The lead content acts as a microscopic chip breaker and tool lubricant during machining, providing excellent machinability characteristics while sealing shrinkage pores to ensure pressure tightness. Leaded brass alloys are classified as low-leaded, medium-leaded, or high-leaded based on their lead content, and they retain the traditional properties of brass, including good corrosion resistance, electrical conductivity, and attractive finish. These alloys are extensively used for screw machine products, valves, fittings, bearings, speciality fasteners, architectural hardware, and general-purpose machine parts where precision manufacturing and durability are essential.

Equivalent leaded brass grades with their ISO symbols and international standards are:
Equivalent leaded brass grades with their ISO symbols and international standards are:
- CuZn36Pb2As (ISO), matching UNS C35330, EN CW602N, BS CZ132, with no JIS or IS equivalents specified.
- CuZn37Pb1 (ISO), corresponding to EN CW605N and IS 319 Grade III, with no UNS, BS, or JIS equivalents listed.
These grades ensure global compatibility and standardisation for leaded brass applications across various manufacturing industries, with ISO symbols providing universal reference points for procurement and engineering specifications.
