ABSTRACT:
An improved composite material, and method of manufacture thereof, comprising varying amounts tungsten powder, or metal/alloy powder of similar density, and clay or silicone is disclosed. The improved composite material may be useful as a replacement for lead and lead-based composites where similar densities are required but the use of lead is undesirable. The disclosed composite material permits a large variety of tungsten powder particle sizes to be utilized and results in improved ductility over known tungsten powder composites.
