Unlike simple trading companies, Fengquan is a physical factory integrating non-ferrous metal casting and precision machining. We understand the pain points of engineers – to resolve the conflict between "high tensile strength" and "economic cost," we focus on providing aluminum bronze bushings and bearings with tensile strengths up to 900 MPa. Relying on domestically leading large-scale centrifugal casting equipment (maximum single piece 20 tons) and German-imported electric furnaces, we ensure that every casting possesses a superior metallographic structure with no porosity and a dense microstructure.
Our aluminum bronze bushings and bearings offer excellent performance and are fully adaptable to complex working conditions.
Our aluminum bronze bushings and bearings (grades: QAL9-4, QAL10-4-4, corresponding to US standard C95500/C95800) exhibit astonishing data under laboratory spectral testing: tensile strengths reaching 600-900 MPa. This means that in heavy-duty bushing applications in mining machinery, it can withstand more than three times the pressure of traditional brass without plastic deformation.
Have you ever encountered the "cold welding" phenomenon between stainless steel shafts and copper bushings in hydraulic systems and explosion-proof scenarios? Our material possesses excellent anti-seizure and self-lubricating properties. Especially in stretching die applications, it will not scratch the workpiece surface like ordinary steel. Simultaneously, it does not generate sparks upon impact, making it the safest supplier of aluminum bronze bushings and bearings for the petrochemical industry.
We strictly control the iron and nickel content during the production process, which gives our products excellent stability in seawater and acidic/alkaline environments. Our engineering team provides a one-stop service from casting to finishing based on your drawings. Utilizing fully automated four-robot systems and large vertical lathes in our factory, we control machining tolerances to the micron level, ensuring that your aluminum bronze bushings and bearings maintain stable mechanical properties even at temperatures up to 400°C.
There are many aluminum bronze bushings and bearings on the market, but very few service providers can handle orders for "2-meter diameter, 20-ton single pieces" and offer a complete heat treatment strengthening solution. Our authority stems from 23 years of practical experience.
We don't just sell inventory; we solve problems. Any standard or non-standard drawings you provide can be addressed at Fengquan. Our team of senior engineers (currently 39 senior technicians) will be deeply involved in your product design phase. For propeller shafts in marine engineering or hydraulic system components in construction machinery, we recommend heat treatment strengthening processes (solution + aging) to further improve hardness and wear resistance.
