从China供应商批发进口Alloy Metal Sleeve Bushing For Pump — FOB条款

This sleeve bushing is a cemented carbide component engineered for pump applications that demand extreme wear resistance and compressive strength. The bushing is produced from a tungsten carbide cobalt alloy, specifically Grade YG8, which contains approximately 92% tungsten carbide and 8% cobalt. The material composition is achieved through a powder metallurgy process that includes tilt ball milling and vacuum stirring drying, ensuring uniform composition and a dense, pore-free structure suitable for high-load industrial environments.

The alloy sleeve is manufactured using primary saturated tungsten carbide and high-purity ultra-fine cobalt powder, with precise carbon blending to optimize hardness and toughness. Grade YG8 is a standard choice for applications like oil field, mining, and chemical processing equipment, where plain bearings must withstand abrasive media and cyclic loading. Typical hardness for this grade ranges from 89 to 91 HRA, with a transverse rupture strength of around 1500 MPa, values that align with industry standards for WC-Co alloys in this cobalt content range.

Industrial buyers source these bushings for use in centrifugal pumps, valves, and rotating machinery where conventional steel or bronze bearings fail under harsh conditions. The component is supplied as a finished sleeve, ready for press-fitting into housings, and is commonly used in equipment exposed to slurry, corrosive fluids, or high-temperature operation. Buyers should confirm dimensional tolerances, surface finish, and the specific pump model compatibility before ordering, as these bushings are often custom-machined to meet exact bore and outer diameter requirements.

Sichuan Burray Cemented Carbide Co., Ltd. is based in the High-Tech Industrial Park in Zigong, Sichuan, China, a region known for its concentration of hard alloy and carbide manufacturing expertise. The company specializes in cemented carbide components, leveraging advanced powder metallurgy techniques to produce parts like sleeve bushings, valves, and wear-resistant tools for industrial applications. Its listed trust tier is harbor, indicating a baseline level of verification for its operational presence.

The supplier’s profile does not specify additional certifications, production capacity, or client references, nor does it provide details on response rates or average lead times. The focus of their listed offerings is on the technical quality of their carbide products, particularly in demanding sectors such as oil and gas, mining, and chemical processing. Buyers should directly confirm the company’s ability to meet specific dimensional, volume, or quality assurance requirements for their projects.
