Product Overview
Beryllium Copper C17200 studs are high-performance threaded fasteners manufactured from a copper-beryllium alloy (UNS C17200) conforming to ASTM B194 and ASTM B196. This precipitation-hardened alloy delivers a unique combination of high strength (up to 1380 MPa), excellent electrical and thermal conductivity, and outstanding resistance to non-sparking and galling in critical bolted assemblies.
Beryllium Copper C17200 studs are widely specified for electrical, aerospace, oil & gas, and marine applications where non-magnetic, corrosion-resistant, and high-strength fasteners are required. They are suitable for use in hazardous environments due to their non-sparking properties and are compliant with NACE MR0175 for sour service.
