Abrasion Resistant Copper Matrix Tungsten Carbide Rod
Copper-matrix route: the low-modulus matrix that cushions carbide under impact while brazing at low heat.
Design and Construction
An abrasion-resistant rod on a copper matrix: the lower-modulus copper cushions carbide fragments under impact, and the braze window sits lower than steel-matrix rods – gentler on the parent part.
How It Works
Under impact the copper matrix flexes microscopically and holds the grit; under abrasion the carbide surface does the work – two mechanisms, one matrix.
Applications
Impact-plus-abrasion duty, heat-sensitive parent parts, repair brazing.
Field Cases
- Mixed duty: the copper matrix held grit where rigid matrices shed it.
- Heat-sensitive part: the low window braze without distortion.
- Repair shop: distortion complaints ended on thin parts.
Performance Data
| Metric | Value / Observation |
|---|---|
| Matrix | Copper – low modulus |
| Impact behaviour | Cushions the grit |
| Braze window | Lower than steel-matrix rods |
| Grit | Tungsten carbide |
Suitable Materials
Heat-sensitive and impact-plus-abrasion parts.
Material Comparison: Copper Matrix vs Steel Matrix Rods
Matrix choice changes the deposit behaviour – typical industry data:
| Factor | Copper Matrix (this rod) | Steel Matrix |
|---|---|---|
| Modulus | Lower – cushions grit | Higher – rigid hold |
| Impact response | Grit flexes and holds | Grit chips if brittle |
| Braze window | Lower – gentle on parent | Higher |
| Thin-part distortion | Minimal | Distortion risk |
| Best duty | Impact + abrasion mix | Pure abrasion |
Delivery Scope
Rod in tube; matrix spec included.
