Chromium briquettes

Briquettes are made by PM method from aluminothermic chromium powder or from the mixture of electrolytic and aluminothermic chromium powders by pressing and subsequent sintering (refining in hydrogen).

Briquettes are intended for alloying steels and manufacturing alloys and for the production of heat-resistant alloys.

The dimensions of the briquettes meet the following requirements:

(Ø40±5,0)×(40±10) mm.

Briquette weight (0,25±0,10) kg (for reference).
