Bronze bushing

Shanghai Tecmetal Import And Export Co., Ltd offers bronze bushings produced by vertical and horizontal centrifugal casting, a method that yields dense, uniform grain structures with reduced porosity compared to sand casting. The bushings are supplied in multiple configurations including plain cylindrical types, flange bushings, and washer formats to suit different mounting requirements. The source material is described as industrial-grade bronze with claimed high tensile strength, excellent wear resistance, and corrosion protection properties, though exact alloy grade and mechanical property values are not stated in the listing. The supplier notes availability in different sizes, but no dimensional tables or standard bore ranges are provided.

Centrifugal casting of bronze bushings typically employs alloys such as CuSn6 (C51900), CuSn8 (C52100), or CuSn10-C (C90700), depending on the required balance of strength, wear resistance, and machinability. The vertical process suits shorter, thicker-walled components, while horizontal centrifugal casting accommodates longer bushings with more consistent wall thickness. Flange bushings incorporate an integral radial flange for axial location, eliminating the need for separate thrust washers in many assemblies. Standard bronze alloys for industrial bushings typically achieve tensile strengths of 200-350 MPa and Brinell hardness values in the 60-120 HB range, though buyers should request certified test reports for the specific alloy supplied.

These components find use in construction equipment pivot joints, automotive suspension and steering linkages, general machinery guide bearings, and heavy equipment hydraulic cylinders where sliding contact occurs under moderate load. Importers typically specify bore diameter, outer diameter, length, flange dimensions if required, and alloy grade against standards such as ASTM B438, DIN 1494, or ISO 3547. The listing mentions FOB and CIF as available Incoterms, but exact MOQ, lead time, and pricing are not disclosed. Buyers should confirm alloy composition certificates, dimensional tolerance classes, and surface finish requirements before placing orders.

Shanghai Tecmetal Import And Export Co., Ltd maintains its registered address at R801, No.839, Zhongjiang Road, Putuo District, Shanghai, 200062, China. The supplier is classified under the 'imported' tier within the marketplace system and holds a 'harbor' trust designation. Notably, the response rate is recorded at 0.00 percent with zero average response hours, indicating that direct communication data is either absent or the supplier has not responded to enquiries through the platform. The company operates as a trading or manufacturing entity based in one of China's primary industrial and shipping hubs, which offers logistical advantages for export-oriented business.

The listing provides no information about factory ownership, production floor area, employee count, annual revenue, year of establishment, or specific clientele. No third-party audit certifications, ISO certificates, or quality management accreditations are displayed. The source description references generic ISO certification without specifying the standard, scope, or certifying body. Buyers should independently verify the supplier's business licence, export licence, and any claimed quality certifications before committing to orders. The absence of response data suggests that enquiry turnaround and English-language communication capabilities should be tested early in the sourcing process.
