Product Description

                 
                       Explosive Welding Rolling Wear Resistant Bimetal Plate

In automobiles, tractors, aircraft and other heavy machinery, a large number of parts, such as bushes, bearings and bushes, are made of friction materials. This kind of part reduces the wear of the mechanical shaft at the cost of its own wear, thereby increasing the service life of the shaft.

With the increase of engine power and speed, the load of bearing increases. At the same time, with the increase of production, the demand for bearing materials is also increasing. In this case, not only the material is required to have better friction and wear properties, but also the cost is lower. As a result, bimetal wear resistant materials came into being. The inner layer of this material is abrasion-reducing material, and the outer layer is cheap ordinary steel, such as lead bronze-steel and aluminum alloy-steel. The emergence and application of these bimetallic metals have made great contributions to the development of the machinery industry.

The service life of bearings and other parts mainly depends on the fatigue strength of wear-reducing materials working under large dynamic loads. And the strength depends on a series of factors, including the physical and chemical properties, microstructure and obtaining methods of bimetallic materials.


The explosive bonding and subsequent rolling process of Henan Chalco was used to obtain the wear-reducing bimetallic materials with good properties. The hardness of the bimetal cladding obtained by explosive welding and rolling is much higher than that of the common rolling under the condition of little thickness difference, which undoubtedly improves the wear resistance.

The hardness of the bimetal cladding obtained by explosive welding and rolling is much higher than that obtained by co-rolling, which undoubtedly improves the wear resistance of some wear resistant bimetal materials.
