| Cobalt Content (Co) | Range 3% to 12% |
| Nickel Content (Ni) | Range 1% to 8% |
| Iron Content (Fe) | Range 0.5% to 3.5% (Nickel-Iron matrix grades) |
| Trace Elements | Combined Titanium, Tantalum, Niobium, Copper (Less than 2%) |
| Physical Form | Broken Solid Carbide Drills, PCB Drills, Inserts, Heavy Alloy Counterweights, Tool Wear Plates |
| Density | 14.2 to 18.2 g/cm3 |
| Hardness | 88 to 93.5 HRA (Carbide Matrix) / 28 to 36 HRC (Heavy Alloy Matrix) |
| Magnetic Behavior | Slightly Magnetic to Magnetic (depending on Nickel-Iron or Cobalt content) |

Grade Segregation: Maintain separate lots for solid tungsten carbide (WC-Co) tool scrap and tungsten heavy alloys (W-Ni-Fe/Co), as they enter different chemical reclamation streams.
Separation Requirements: Steel shanks, copper/silver brazing joints, and foreign metallic attachments must be fully removed to avoid price deductions.
Recycling Pathways: Processed via zinc process reclamation, direct hydrometallurgical recycling, or chemical processing into ammonium paratungstate (APT).
