Working with Ni Briquette Ni9990-BRIQ
Is Ni Briquette easy to machine?
Not machined as supplied; consolidated pure nickel is gummy and work-hardens — use sharp positive-rake tools, heavy feed, low speed and flood coolant.
Can Ni Briquette be welded?
Very low sulphur makes it weld-friendly; when melted into alloys keep it dry and oil-free to avoid porosity, and use Ni-filler (ERNi-1) for wrought nickel joints.
Can Ni Briquette be formed, bent or molded?
Feedstock form — charge into EAF/AOD/VIM or dissolve in plating/sulphate baths; briquette size gives fast, predictable dissolution and accurate weighing.
What surface finishes work on Ni Briquette?
Not anodizable; nickel itself is the plating/electroforming anode metal. Store dry and sealed — briquettes oxidise/tarnish and pick up moisture in humid warehouses.

Ni Briquette Ni9990-BRIQ has a typical yield strength of 165 MPa (23.9 ksi) and a tensile strength of 440 MPa (63.8 ksi) — weaker than 96% of nickel alloy grades. Strength varies by condition: see the 4 listed tempers.
Is Ni Briquette Ni9990-BRIQ easy to machine?
Reasonably — machinability is rated fair (45/100, better than 99% of nickel alloy grades). Not machined as supplied; consolidated pure nickel is gummy and work-hardens — use sharp positive-rake tools, heavy feed, low speed and flood coolant.
Can Ni Briquette Ni9990-BRIQ be welded?
Yes — weldability is rated very good (72/100). Very low sulphur makes it weld-friendly; when melted into alloys keep it dry and oil-free to avoid porosity, and use Ni-filler (ERNi-1) for wrought nickel joints.
What surface finishes work on Ni Briquette Ni9990-BRIQ?
Not anodizable; nickel itself is the plating/electroforming anode metal. Store dry and sealed — briquettes oxidise/tarnish and pick up moisture in humid warehouses.
Can Ni Briquette Ni9990-BRIQ be formed, bent or molded?
Feedstock form — charge into EAF/AOD/VIM or dissolve in plating/sulphate baths; briquette size gives fast, predictable dissolution and accurate weighing.
What is the maximum service temperature of Ni Briquette Ni9990-BRIQ?
Ni Briquette Ni9990-BRIQ is rated for continuous use to about 315°C (599 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
