Product Usage:
The product is improved on the basis of pre-mixed bronze powder. The effect of temperature on the rate of change of sintering size is further reduced. It is suitable for the preparation of medium and high-grade oil bearing. It can be directly pressed and formed. After adding solid lubricant such as graphite and molybdenum disulfide Forming sintering.
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
