What is Ni Shot-NI9990?
Ni Shot-NI9990 is Ni Shot in the NI9990 grade — standard commercial purity class (GB/T 6516 Ni9990 / ASTM B39) for general steel, iron and plating use. Ni Shot-NI9990 has a yield strength of 120 MPa (17.4 ksi) and a tensile strength of 420 MPa (60.9 ksi) — weaker than 99% of nickel alloy grades. Elongation at break is 45% and the elastic modulus is 207 GPa (30 Msi). Ni Shot-NI9990 has a density of 8.9 g/cm³ (0.322 lb/in³), heavier than 91% of nickel alloy grades. It melts at 1,453°C (2,647 °F).
Advantages
- High electrical conductivity — 24.5 % IACS, better than 100% of nickel alloy grades
- Conducts heat well — 88 W/m·K (50.8 BTU/hr·ft·°F), better than 99% of nickel alloy grades
Limitations
- Low strength — 120 MPa (17.4 ksi), worse than 99% of nickel alloy grades

Working with Ni Shot-NI9990
Is Ni Shot easy to machine?
Not a machining stock — shot is a charge material; if wrought pure nickel is machined it is gummy and needs sharp positive-rake tools, slow speeds and flood coolant.
Can Ni Shot be welded?
Not welded as supplied; the nickel it delivers is fully weldable in the finished alloy, and low S/C in the shot protects weld hot-cracking resistance.
Can Ni Shot be formed, bent or molded?
Charge dry, preheated shot into the melt after slag control; recovery in steel/iron heats is typically 97–100 % with fast dissolution due to the high surface-to-mass ratio.
What surface finishes work on Ni Shot?
Store sealed and dry to avoid surface oxidation and moisture pick-up; no coating or passivation applied to the shot itself.
