Product Usage:
Used in 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-alloy bronze powder and contains a lubricant, can be directly pressed into the powder, in a reducing atmosphere sintering.
Product Features:
No segregation
· Excellent mobility and formability
High growth embryo strength
Sintering size, sintering size changes stable
· Oil hole distribution is uniform and meticulous
Suitable for thin-type oil-bearing
