Quality requirements
Stacks should not have fat and oil spots on the surface and tarnish colors, the fracture should be of a crystalline texture and have a light gray color.
For the MBMS-1 stacks, the presence of stratifications, surface cracks, chips, shells, melts is not a sign of rejection.
On the surface of the MBS-2 grades, the presence of unevenness, chips and traces of reflow is not allowed.
The non-straightness of the MBS-2 headbands should not exceed 2 mm by the length of the bar. Delivery is possible with non-straightness up to 3 mm in an amount up to 25% of the weight of the batch.
The powder should be gray in color without foreign inclusions, and also contain not less than 92% of grains up to 5 microns in size.
