Frequently Asked Questions (FAQ)
We use 100% virgin sub-micron and ultra-fine tungsten carbide powder blended with premium cobalt binder. Recycled or low-grade materials are never used, ensuring optimal hardness, wear resistance, and transverse rupture strength.
We provide precision ground solid carbide rods with standard ISO h5 and h6 outer diameter tolerances. Custom tolerances down to -0.005mm and mirror surface polishing with Ra ≤ 0.05μm can also be manufactured upon request.
Our solid carbide rods are engineered for manufacturing rotary tools used on cast iron, general carbon steels, hardened alloys, stainless steel, heat-resistant superalloys, nickel-base alloys, and titanium alloys.
Yes. In addition to standard 310mm and 330mm long rods, we supply unground and precision-ground cut-to-length rods according to customer-specified lengths, along with single or double-end chamfer processing.
Every batch of carbide rods is secured in impact-absorbing plastic tubes or partitioned foam boxes before being packed into reinforced export cartons to eliminate vibration impact during sea, air, or international express shipping.
