NiCr20 (Ni80Cr20) is a premium nickel-chromium alloy powder renowned for its exceptional high-temperature oxidation resistance, corrosion resistance, and excellent electrical stability. Operating effectively at temperatures up to 1200°C, it forms a dense, protective chromium oxide layer that prevents further substrate degradation. It is widely utilized in thermal spray coatings for surface protection, heating element fabrication, and advanced metal additive manufacturing (3D printing).
Key Product Features：
-
High Operating Temperature: Stable performance up to 1200°C.
-
Dense Protective Oxide Layer: Outstanding resistance to scaling and sulfidation.
-
Thermal Shock Resistance: Minimal thermal expansion mismatch, ideal for cycling conditions.
-
Versatile Processing: Excellent flowability, perfect for HVOF, APS, and Additive Manufacturing.

FAQ
Q: What is MIM feedstock?
A: MIM feedstock is compound of metal powder + polymer binder. It is the raw pellet material fed directly into injection molding machine for MIM production.
Q: What debinding type should I choose for 316L MIM feedstock?
A: Catalytic debind is preferred for mass production. Thermal debind is better for small batches. We can adjust formula based on your furnace.
Q: Can I get free sample?
A: We offer trial samples for process evaluation. Please contact our sales team for sample quotation.
Q: Is 316L MIM material corrosion resistant?
A: Yes. Sintered 316L MIM parts have excellent resistance against salt water, acid and humid environment.
