BIMETALLIC BARREL
 
Bimetallic" means that two different metals are fused together in a high temperature furnace that subjects the two metals to temperature of more than 1100 ¡æ High revolution spinning of the white -hot cylinder fuses the inlay alloy to the bore wall. Subsequent carefully controlled cooling creates a super-hard, highly uniform lining in the cylinder bore that is further subject to a ultra-precise honing process. The finished bore lining is at least 1.5mm thick.

BIMETALLIC SCREW
 
¡°Bimetallic screw¡± means that the wear (working) surfaces (primarily of flight lands, special complete screw) are usually protected by welding special wear resistant alloys over these surfaces. Screw is further subject to ultra-precise mechanical process. The final thickness of the hard-surfacing materials is usually around 1.5mm.
