1. What is MP35N Alloy Wire?

MP35N Alloy Wire is a cobalt-nickel-chromium-molybdenum alloy wire designed for applications requiring exceptional strength, fatigue resistance, corrosion resistance, toughness, and reliability.

2. What is MP35N wire used for?

MP35N wire is used in medical devices, implantable components, springs, aerospace systems, defense applications, precision instrumentation, high-strength cables, and other demanding mechanical applications.

3. What is the composition of MP35N?

MP35N typically contains approximately 33–37% nickel, 19–21% chromium, and 9–10.5% molybdenum, with cobalt making up the balance and very low carbon, manganese, and silicon levels.

4. Can MP35N wire be supplied in different tempers?

Yes. REG Metals can source solution-treated, annealed, cold-worked, age-hardened, and custom heat-treated conditions, depending on the required mechanical properties.

5. What specifications apply to MP35N wire?

Common specifications include ASTM F562 and AMS 5844, depending on the application and required product condition.

6. Does REG Metals provide a Certificate of Analysis?

Yes. A Certificate of Analysis (COA) can be supplied documenting chemical composition, wire diameter, mechanical properties, heat treatment, temper, surface condition, dimensional tolerances, and applicable specification compliance.
