Aluminum-based strips are mostly used to manufacture engine bearings,bushings and thrust washers for various engines of automobile and engineering machines. Company manufactures various kinds if aluminum-based and lead-free strips.

Technical Standards for Aluminum-based Strips:

.Main grade and their chemical composition of aluminum-based material:(Table-2)

.Steel back :adopt carbon structure steel plates with low carbon or the material requested by customers.

.Surface roughness of steel back:Ra0.63 m

Dimension and allowable deviation (Table-3)

The range of thickness:1.0-18.0mm

The range of width :10-250mm

1.Copper-based alloy powder

   We adopt water atomization method to manufacture the copper-based alloy powder.The quality of our products is quite reliable and stable.Our various specifications of powder are widely used to produce copper lead strips for engine bearings and bushings, and to manufacture other powder metallurgy products.

Besides our commonly used specifications ,we are able to produce powder according to the customers requests.
