Durable Tungsten Carbide Sleeve and Bushing
Durable tungsten carbide sleeves and bushings from Sichuan Burray Cemented Carbide Co., Ltd. are manufactured from ultra-fine WC-Co cemented carbide, with cobalt binder content typically between 6% and 12%. The product is produced using vacuum sintering and pressure-assisted densification to achieve densities above 14.5 g/cm³, ensuring high hardness and minimal porosity. These components are precision-ground to tight tolerances for use in high-wear mechanical interfaces.
The material composition follows standard cemented carbide grades such as YG6, YG8, or YG15, though the listing does not specify the exact grade. The sintering process includes tilt ball milling and digital degreasing to ensure homogeneity. Unlike sintered steel or bronze alternatives, tungsten carbide maintains dimensional stability under extreme pressure and temperature, making it suitable for oilfield drilling tools and mining equipment where abrasion resistance is critical.
These sleeves and bushings are primarily used in valve stems, drill bits, hydraulic pistons, and wear plates in heavy machinery. Buyers include manufacturers of oil and gas equipment, mining machinery, and industrial tooling suppliers. Trade terms are offered per kilogram with flexible MOQs, and delivery is typically via sea freight from Chengdu or Chongqing ports. Lead time is approximately 30 to 45 days after order confirmation, subject to customization.
| Material | WC-Co cemented carbide (tungsten carbide with cobalt binder) |
| Typical cobalt content | 6% to 12% by weight, standard for wear-resistant carbide grades |
| Hardness | Typical HRA 88 to 92, corresponding to 1300 to 1500 HV30 |
| Density | 14.5 g/cm³ to 15.0 g/cm³, typical for fine-grain WC-Co |
| Grain size | Ultra-fine, typically 0.3μm to 0.8μm, per standard powder metallurgy practice |
| Compressive strength | Typical: 3500 MPa to 4500 MPa |
| Flexural strength | Typical: 1800 MPa to 2200 MPa |
| Tolerance range | ±0.005mm to ±0.02mm, standard for precision-ground carbide components |
| Surface finish | Ra 0.2μm to 0.4μm after grinding, typical for sealing and sliding interfaces |
| Standard grades | Typical equivalents: YG6, YG8, YG15, or ISO K10 to K40 |
Sichuan Burray Cemented Carbide Co., Ltd. operates from the High-Tech Industrial Park in Zigong, Sichuan Province, China. The supplier specializes in cemented carbide components using advanced powder metallurgy processes including tilt ball milling, vacuum sintering, and pressure sintering. The listing confirms production capability but provides no details on workforce, annual output, or client references.
The company is identified as a harbor-tier supplier with no verified certifications, quality system audits, or export history visible in the data. While the description mentions precision post-processing and specialized manufacturing, there is no mention of testing equipment, in-house metrology, or compliance with ISO 9001 or ASTM B289. All claims are based on process descriptions, not third-party validation.
This tungsten carbide sleeve and bushing is manufactured from high-purity ultra-fine WC-Co cemented carbide, offering superior wear resistance and compressive strength for demanding industrial applications. Widely used in oilfield drilling, mining equipment, and mechanical engineering, these sleeves and bushings provide extended service life in high-friction and high-pressure environments. Ideal for global import/export trade, priced competitively per kilogram with flexible MOQ terms.

Sourcing Durable Tungsten Carbide Sleeve and Bushing from Sichuan Burray Cemented Carbide Co., Ltd. - China Import Guide
Before ordering, confirm the exact WC-Co grade and cobalt percentage, as these determine performance in your application. Request a material certification with density, hardness, and grain size for each batch. Since no certifications are listed, insist on test reports from an independent lab. Verify that the supplier uses ISO 4492 or ASTM B289 for material specification compliance.
Confirm Incoterms - typically FOB Chongqing or CIF destination port - and clarify if export documentation is included. Lead time is 30 to 45 days due to sintering cycles and grinding processes. Payment terms are often 50% advance, 50% against shipping documents. Ask for packaging details: carbide components must be individually wrapped in foam and packed in rigid boxes to prevent chipping during transit.
Inspect each batch for surface cracks, chipping, or discoloration. Use a Rockwell hardness tester to verify HRA within ±1 point of the specification. Measure internal and external diameters with a micrometer or bore gauge to ensure tolerance compliance. Request a dimensional inspection report and retain a sample for future comparison. Confirm that the supplier provides traceability by batch number.
