Description

Quick Detail:

C18150 is precipitation-hardened chromium zirconium copper alloy (UNS C18150, CW106C). Our factory supplies precision-drawn C18150 wire with stable dimensional tolerance and consistent material performance. Balancing high electrical conductivity, mechanical strength and high-temperature softening resistance, C18150 maintains excellent hardness and structural stability under continuous thermal cycling. Its conductivity reaches ≥80% IACS after aging treatment, with outstanding wear resistance and anti-sticking property compared to pure copper.

Wire size from Dia.1.0mm ~ Dia.6.0mm

Key Characteristics & Advantages:
• Excellent electrical & thermal conductivity

• High resistance to softening up to 500°C

• Good ductility for cold forming & heading

• Superior thermal fatigue and creep resistance
