890-950 C Carbide Composite Rods and Tungsten Carbide Granules
The temperature window published on the rod: 890-950 C – braze inside it and the carbide never melts.
Design and Construction
Composite rods published with their working window: 890-950 C. Inside the window the CuZnNi matrix flows and the tungsten carbide granules stay solid – the discipline the window enforces protects the edge.
How It Works
The matrix melts at the window; the carbide melts far higher – staying inside the window is what keeps the fragments sharp in the finished skin.
Applications
Quality-controlled brazing, training environments, spec-driven shops.
Field Cases
- QC brazing: window discipline ended the melted-carbide rejects.
- Training: the window taught new brazers in one session.
- Spec shop: the published window went into the work instruction.
Performance Data
| Metric | Value / Observation |
|---|---|
| Working window | 890-950 C published |
| Carbide melt | Far above the window |
| Result inside window | Matrix flows, carbide stays sharp |
| Rod | Composite, carbide granules |
Suitable Materials
Steel parts for braze-on hardfacing.
Material Comparison: Inside the Window vs Overheating
What the extra 100 C costs – typical industry data:
| Factor | Inside 890-950 C | Overheated |
|---|---|---|
| Matrix behaviour | Flows, wets properly | Runs thin, drains |
| Carbide state | Solid – sharp fragments | Partial melt – rounds edges |
| Wear life claim | Full | Reduced |
| Reject rate | Low | Melted-carbide rejects |
| Fix | Stay in window | Skill-dependent |
Delivery Scope
Rod in tube; window card included.

Frequently Asked Questions
Why publish the window?
Inside it the carbide never melts – the discipline protects the edge.
What if overheated?
Matrix drains and carbide edges round – rejects.
Card?
The window card ships with the rod.
Melt test?
Batch verification of the window.
Training?
One session with the card.
