CuCr1Zr (CW106C) vs CuFe2P
Side-by-side chemical composition and mechanical property comparison.
Overview
CuCr1Zr (CW106C)
CW106C
Chromium-zirconium copper alloy, precipitation hardened. High electrical/thermal conductivity (~80% IACS) with significantly higher strength and hardness than pure copper. Age-hardened: Rm 440–540 MPa, Rp0.2 380–480 MPa, HB 130–170. Softening temperature ~500°C. UNS C18150, EN CW106C. Applications: resistance welding electrodes and caps, continuous casting molds, circuit breaker contacts, lead frames, MIG welding tips. THE standard electrode material.
CuFe2P
CW107C
Precipitation-hardened copper-iron alloy — THE semiconductor leadframe material since 1964. Fe precipitates give UTS up to 580 MPa while maintaining 60-65% IACS electrical conductivity. Resists softening to 350°C (critical for IC packaging). Also used for automotive connectors, pin grid arrays (PGA), and terminals. Trade names: Wieland K65, Aurubis PNA212.
