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.

Manufacturing Process
1. Testing Method
(1) Chemical Composition Analysis - Verified using techniques
such as GDMS or XRF to ensure compliance with purity requirements.
(2) Mechanical Properties Testing - Includes tensile strength,
yield strength, and elongation tests to assess material performance.
(3) Dimensional Inspection - Measures thickness, width, and
length to ensure adherence to specified tolerances.
(4) Surface Quality Inspection - Checks for defects such as
scratches, cracks, or inclusions through visual and ultrasonic examination.
(5) Hardness Testing - Determines material hardness to confirm
uniformity and mechanical reliability.

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).
