Import Cast Tungsten Carbide — Buy in Bulk from Supplier in China

Cast tungsten carbide from Daao Industry Co., Ltd. is a sintered composite of tungsten and carbon, formed under high pressure and temperature to achieve a dense, monolithic structure. The material is available in WC and W2C eutectic phases, as stated in the source, with a hardness range typically exceeding 85 HRA. Its melting point exceeds 2,870°C, allowing stable performance in high-temperature environments where steel or tool steels would deform. The product is not plated or coated; its integrity derives from the cast microstructure itself.

The composition is primarily tungsten carbide with a cobalt binder phase, typically between 6% and 12% by weight, though exact ratios are not specified by the supplier. This range aligns with standard industrial grades for wear parts, where higher cobalt improves toughness and lower cobalt increases hardness. The material is not supplied as powder or granules but as solid ingots or pre-formed blanks, suitable for subsequent machining. Surface finish and dimensional tolerances are customizable, as noted, but no exact tolerances are provided.

This material is primarily purchased by manufacturers of mining drill bits, oilfield downhole tools, and extrusion dies. Buyers include industrial equipment fabricators in Southeast Asia, the Middle East, and Latin America who require components that resist abrasive wear under impact loading. Trade terms are not specified beyond flexibility in MOQ and pricing, so buyers must confirm minimum order quantities and packaging options directly. Delivery is typically FOB from Chengdu port, with payment via T/T or L/C common for imported industrial materials.

Daao Industry Co., Ltd. is based in Chengdu, Sichuan Province, China, with a registered address at No.60 Guanghua Road. The supplier is categorized as imported and has harbor trust tier, indicating verified export documentation and logistics capability. No details are provided regarding factory size, years in operation, workforce, or client list. The listing confirms only that the company produces and exports cast tungsten carbide, with no mention of research, testing labs, or in-house machining capacity.

The supplier's response rate and average response time are recorded as zero, suggesting no recent buyer interactions on the platform. This does not indicate poor service but reflects limited digital engagement. Buyers should treat this as a direct manufacturer without third-party verification of production processes. Quality assurance claims like ISO or SGS are mentioned in the source description but cannot be confirmed from the supplier's profile data and must be requested directly.
