Selective compliance assembly robot arm

A composite tungsten carbide insert (B, I) with heterogeneous composition and structure has a working part (W) and a non-working part (N). The working part (W) is made of a tungsten carbide material consisting of tungsten carbide powder and cobalt powder or nickel. The non-working part (N) is made of a low density tungsten carbide material consisting of titanium carbide powder, tungsten carbide powder, and cobalt powder or nickel powder. During pressing, the tungsten carbide material for the working part (W) and the low density tungsten carbide material for the non-working part (N) are weighed and added to a steel die successively for molding and then sintering. The non-working part (N) which accounts for most of the overall product volume has low density and less material consumption, and can greatly reduce the raw material costs of the product, significantly improving the performance-cost ratio of the insert (B, I).
