ABSTRACT:
The invention provides a sinterable brass powder blend, comprising about 90% to about 99% by weight of brass powder, about 0.2% to about 6.0% by weight manganese sulfide, and 0% to about 5.0% by weight of lubricants, binders, graphite, sintering enhancing additives and mixtures thereof.
The invention also provides methods for making lead-free but machinable sintered brass powder metal parts.
