Copper Silicide (Cu5Si) Powder CAS 12159-07-8

Copper Silicide (Cu5Si) is a high-conductivity intermetallic compound designed for applications requiring exceptional electrical performance, thermal stability (melting point ~800°C), and corrosion resistance. This reddish-brown crystalline material combines copper’s superior conductivity with silicon’s durability, making it ideal for advanced electronics, conductive coatings, and industrial components in harsh environments.

High Electrical Conductivity: Near-pure copper performance with improved oxidation resistance.
Corrosion Resistance: Stable in saline, acidic, and humid environments (pH 3–12).
Thermal Stability: Maintains structural integrity up to 600°C in air.
Cost-Efficiency: Combines copper’s benefits with silicon’s cost-effective hardening effects.
