Product Usage:
Diffused brass powder for the production of powder metallurgy self-lubricating oil bearing, used in portable personal electronic devices, office services machines, mechanical parts, motors and so on. For the pre-alloyed brass powder and containing the lubricant, it can be directly pressed into a powder and sintered in a reducing atmosphere.
Product Features:
Not segregated
· Excellent mobility and formability
High growth embryo strength
Sintering size, sintering size changes stable
· Oil hole distribution is uniform and meticulous
