Copper Alloys Guide

Pure Copper

T2 copper: 100% IACS conductivity, for electrical busbars and cables. Oxygen-free copper TU1/TU2 for vacuum electronics.

Brass (Cu-Zn)

H62 (62%Cu): most common structural brass. H68 (68%Cu): for deep drawn parts. HPb59-1: free-cutting leaded brass for valves. Lead-free brass now standard for drinking water.

Bronze

QSn6.5-0.1 phosphor bronze: spring contacts. QAl9-4 aluminum bronze: marine propellers. QBe2 beryllium bronze: over 1200MPa strength, spark-free.
