Description

Quick Detail:
C17500 alloy is a precipitation-hardened beryllium-cobalt copper alloy renowned for its exceptional balance of high strength, electrical/thermal conductivity, and corrosion resistance.
Rod size from Dia.1mm - Dia.75mm

 

Key Characteristics & Advantages:
Corrosion Resistance:excellent in seawater, freshwater, and atmospheric conditions (corrosion depth: 0.01–0.14 mm/year)35. Resists sulfuric acid (<80% concentration) but vulnerable to ammonia/nitric acid36.
Special Characteristics:Non-magnetic, spark-free on impact. Retains properties from cryogenic (−196°C) to elevated temperatures (300°C).
Machinability: 20–40% of free-cutting brass (requires carbide tools with cooling).
Formability/Weldability: Excellent cold/hot workability (e.g., forging, extrusion). Compatible with TIG, laser, electron beam, and brazing techniques

Core Applications:

Electronics: Connectors, relay springs, switch components.

Welding Equipment: Electrodes for spot/seam welding (especially stainless steel/high-nickel alloys).

Mold Tooling: Injection mold cores, blow-molding inserts (exploits thermal conductivity for rapid cooling).

Aerospace/Marine: Fasteners, bearings, submarine cable repeaters (due to seawater resistance).
