Physical Properties
Material form, density, and contamination specifications.
Post-use tungsten carbide cutting tools; end-of-life machining equipment inserts; ultra-high-value tungsten compound material (70-90% WC + 5-15% cobalt binder); specialized carbide recycling infrastructure; CONCENTRATED LIMITED SUPPLY (98 suppliers; specialty industrial focus); ULTRA-PREMIUM PRICING TIER; tungsten metal strategic value high; cobalt rare earth element importance; carbide-specific expertise required; environmental tungsten recovery critical; supply-constrained specialty commodity
Acceptable Inclusions
- Tungsten carbide 70-90% (carbide specification)
- Cobalt binder 5-15% (rare earth component; valuable)
- Carbon 5-15% (inherent in WC compound)
- Nickel <1% (secondary binder)
