C95800 Aluminum Bronze Bushings And Bearings 10-4-4

The core advantages of C95800 Aluminum Bronze Bushings And Bearings 10-4-4 lie in its seven core properties: high strength, high hardness, ultra-wear resistance, strong corrosion resistance, high-temperature stability, spark-free explosion-proof performance, and self-lubrication. Its comprehensive performance far surpasses that of ordinary copper alloys and approaches that of medium- and low-carbon steel, making it an economical and high-quality alternative to high-cost materials such as nickel-based alloys and stainless steel. In terms of strength and hardness, this product boasts a tensile strength of 690–900 MPa, a yield strength of 300–400 MPa, and a Brinell hardness (HBS) of 170–240. It can withstand extremely high load pressures without easily undergoing plastic deformation or crushing, completely solving the problem of deformation and fracture under heavy loads in ordinary bushings. 

Regarding wear resistance, its dry friction coefficient is as low as 0.25, reducing wear by 40% when paired with bearing steel. Its service life is more than three times that of ordinary tin bronze components, maintaining stable performance even under high-load sliding friction conditions, significantly extending equipment maintenance cycles. In terms of corrosion resistance, it can withstand a wide range of corrosive environments with pH values of 2–12. Its seawater corrosion resistance is 5–8 times that of ordinary brass, resisting atmospheric, freshwater, seawater, and various acidic and alkaline media, especially chloride ion corrosion, making it perfectly suited for highly corrosive environments such as marine engineering and chemical equipment.

Furthermore, C95800 Aluminum Bronze Bushings and Bearings 10-4-4 possess stable mechanical properties below 400℃ and high-temperature stability with a strength retention rate exceeding 65% at 500℃, making them suitable for medium- and high-temperature operating conditions. Their spark-free nature ensures they do not generate sparks upon impact, making them suitable for explosion-proof tools and flammable and explosive environments. Excellent anti-galling and self-lubricating properties ensure a stable coefficient of friction when mating with steel shafts, preventing adhesion and enabling oil-free lubrication in some applications, reducing lubrication costs and the risk of failure. 

As the original manufacturer, we strictly adhere to ISO9001 quality system certification, rigorously controlling quality throughout the entire process from raw material smelting, precision casting, heat treatment strengthening to precision machining. Each batch of products comes with a third-party material testing report, ensuring the stable and reliable performance of C95800 aluminum bronze bushings and bearings 10-4-4. This helps customers reduce costs, increase efficiency, and ensure safe operation of their equipment, making them the preferred choice for heavy-duty wear-resistant industrial components.

We understand that high-quality raw materials are merely the foundation; exquisite craftsmanship is the guarantee of quality. Our C95800 Aluminum Bronze Bushings and Bearings 10-4-4 undergo a rigorous heat treatment process (solution treatment + aging or quenching + tempering) to further enhance their strength and hardness (Brinell hardness HBS 170–240).

In the machining process, we utilize advanced hot forging and rolling technology (850–1000℃) to ensure a dense internal structure, free of porosity and sand holes. Our machining workshop is equipped with high-precision CNC machine tools, enabling us to provide finished bushings with extremely high tolerances according to customer drawings. Before each batch of products leaves the factory, it undergoes spectral analysis, tensile testing, and hardness testing to ensure compliance with ASTM B148 and customer-specific standards.
