Tungsten carbide micro powder is the foundation of durable, high-precision cutting tools. It provides exceptional hardness, heat resistance, and wear durability for demanding industries. For Chinese manufacturers and OEMs, sourcing from a trusted producer like Rettek ensures uniform particle size, optimized binder bonding, and reliable tool performance across mining, machining, and heavy-duty manufacturing applications.
How is tungsten carbide micro powder applied in cutting tools?
Tungsten carbide micro powder acts as the hard phase in cemented carbide, crucial for creating tools with superior wear resistance and thermal stability. Mixed with cobalt binders and processed through pressing and sintering, it forms the cutting edges used in inserts, blades, and drills. Rettek’s integrated production system ensures consistent quality across each manufacturing step, meeting stringent OEM standards.
What properties make tungsten carbide micro powder ideal for OEM wear parts?
The unique balance between hardness (HRA 88–93) and fracture toughness gives tungsten carbide long-lasting wear resistance under extreme conditions. For OEM applications, Rettek ensures fine-tuned control over grain size and binder ratio to meet specific tool requirements. This results in dependable performance, minimized tool breakage, and extended life in both mining and milling operations.
| Key Property | Typical Range | Impact on Tool Performance |
|---|---|---|
| Grain Size | 0.5–3 µm | Smaller grains increase hardness |
| Binder (Co%) | 6–15% | Higher binder improves toughness |
| Density | 14–15 g/cm³ | Ensures stability and uniform strength |
