How wheels are made
From powder to finished wheel, in-house
Pressing, sintering and infiltration happen under one roof; finish machining runs on our own 15-lathe cell. Nothing is subcontracted.
-
01
Powder & mixing
Tungsten powder blended with copper binder in 3-D mixers, weighed per batch record.
-
02
Pressing & sintering
Cold isostatic pressing to near-net shape, then high-temperature sintering in vacuum furnaces.
-
03
Copper infiltration
Molten copper infiltrates the tungsten skeleton — the heart of the W/Cu composite.
-
04
Machining & QC
Turned, milled and ground to 0.02 mm runout; composition, density and hardness verified per batch.
Quality control
Every batch, on the record
- Chemical composition analysis
- Density measurement
- Hardness testing
- Electrical conductivity
- Tensile strength
- Metallographic examination
Tests run per batch and per customer specification; inspection records accompany every shipment. ASTM B702-compliant third-party testing is available on request (~2 weeks, quoted with your order).
Batch traceability: each wheel carries a batch code that maps back to powder lot, furnace run and inspection record.
