Milled powder mixtures are unsuitable for automatic pressing in comparison to agglomerated carbide-cobalt powder mixtures.

Milled powder mixtures are unsuitable for automatic pressing in comparison to agglomerated carbide-cobalt powder mixtures. Correct Answer True

Milled powder mixtures are unsuitable for automatic pressing due to their very poor flow properties, while the agglomerated carbide-cobalt mixture is required for compaction due to their high apparent density and good flow properties in automatic press. Hence, the powders containing about 2% lubricant are frequently agglomerated by compacting them (e.g. pressure= 3.5 tsi).
