Elgiloy® exhibits remarkable corrosion-resistant properties, including high resistance to pitting, crevice, and stress corrosion. It is also resistant to sulfide stress corrosion cracking and is thus highly resistant to sulfide environments that are met in the harsh sour well or marine applications. Chromate and molybdenum addition boosts passivity and hence the alloy becomes practically immune to crevice and stress corrosion in many aggressive environments.
What alloy forms does elgiloy® have, and how do suppliers offer wire, coils, or datasheets?
Compact discs, medical wire, and coils are just some examples of the product forms in which elgiloy® can be found. Along with the alloy wire, reputable suppliers also provide a data sheet and material certification that detail the composition, mechanical properties, tensile and fatigue data, heat treatment instructions, and conformity to standards like ASTM, AMS, or ISO 5832-7 if applicable. When placing your order, be sure to request mill certificates and traceability to ensure that the appropriate cobalt-chromium-nickel-molybdenum alloy variant is supplied.
Is elgiloy® the alloy of choice for dental, orthopedic, and demanding medical devices? If yes, why?
Elgiloy® is often the alloy of choice for dental products, specific orthopedics components, and demanding surgical implants because it gives a unique combination of very high strength, excellent corrosion resistance, good ductility, and outstanding fatigue performance. Its biocompatibility, nonmagnetic nature, and age-hardening capability enable designers to use thinner, more durable components. For critical devices, compliance with standards (ASTM F1058, ISO 5832-7) ensures quality and traceability throughout the supply chain.
