Title:
HIGH DENSITY NON-TOXIC COMPOSITES COMPRISING TUNGSTEN, ANOTHER METAL AND POLYMER POWDER
Document Type and Number:
WIPO Patent Application WO2003033753
Kind Code:
A3
Abstract:
Tungsten/polymer composites comprising tungsten powder, another metal powder having a high packing density, and organic binder have high density, good processibility and good malleability. Preferably, the other metal is a stainless steel, iron, ferrous alloy, or bronze. The organic binder remains part of the finished article after processing and becomes part of he matrix for holding the composite together. Such composites are useful as lead replacements, particularly in the manufacture of shot.
