NC6634 Nickel Cobalt Alloy Lump/ Particles (Ni50/Co50)

Nickel Cobalt Alloy Lump/ Particles (Ni50/Co50) Description

Nickel Cobalt Alloy (Ni50/Co50) features a face-centered cubic (FCC) structure, ensuring excellent ductility (>30% elongation) and high-temperature stability (melting point ~1455°C). The equiatomic composition balances nickel’s oxidation resistance with cobalt’s strength retention at elevated temperatures. Particles exhibit high sphericity (>90%), low oxygen content (<500 ppm), and uniform size distribution (15-150 μm), ideal for laser powder bed fusion (LPBF) or sintering. Lumps are vacuum-arc remelted to minimize impurities (C <0.02%, S <0.005%), ensuring consistency in critical applications like turbine blades and Li-ion battery cathodes. Magnetic properties (saturation magnetization ~1.6 T) suit electromagnetic shielding and permanent magnets.

Nickel Cobalt Alloy Lump/ Particles (Ni50/Co50) FAQs

Q1. Why choose a 50:50 Ni/Co ratio?

Balances nickel’s corrosion resistance with cobalt’s high-temperature creep resistance, ideal for thermal cycling environments.

Q2. Can these particles be used in binder jetting?

Yes, but optimal performance requires 15-45 μm particles with flowability <25 s/50g.

Q3. How does Ni50/Co50 compare to Inconel 718?

Higher Co content improves thermal stability (>1000°C service) but reduces room-temperature tensile strength (650 MPa vs. 1276 MPa).
