Properties of zinc-base wear-resistant alloy

As a superior material for wearing parts,the zinc-base wear-resistant alloy performs the character of abrasion and wear resistance very well. Compare to the copper alloy,it greatly helps to prolong the duration of mechanical transmission parts, machining precision, extend maintenance period of equipments and improve the production efficiency. With a high lubricant adaptability and conductivity, it works well on heat dissipation, temperature controll and anti-seizing effects.

Advantages of zinc-base wear-resistant alloy

Low speciflc gravity and economic. High abrasion and wear resistance,durable. Effects well on heat dissipation and anti-seizing.

Application of zinc-base wear-resistant alloy bearings

Zinc-base wear-resistant alloy bearing is applied to all kinds of construction machinery to replace the tradition copper alloy made products, such as bush, shell, sliding block, sliding plate, gear, worm-gearing and etc.

In recent years, it is gradually used in metal forming machine, water pump, injection machine, crane and other equipments, and achieved successfully in steel rolling, oil, mine and valve industries.
