We are a professional enterprise integrating non-ferrous metal casting and machining. With strong technical capabilities and comprehensive testing methods, it holds multiple certifications. Its products rank among the top in China in terms of production and sales, and are exported globally and applied in various major projects. The factory specializes in high-quality Tin Bronze Bushings and Bearings, using carefully selected national and American standard materials manufactured with advanced processes. These products offer advantages such as wear resistance, non-deformation, and self-lubrication. Specifications can be customized, and the product utilization rate exceeds 95%, precisely meeting the needs of multiple fields.
These Tin Bronze Bushings and Bearings also possess corrosion resistance, high strength, and easy processing characteristics. They are non-magnetic, impact-resistant, and do not generate sparks, solving various problems in equipment operation and suitable for industries such as shipbuilding, mining, and water conservancy. The company supports customization, offering short lead times, high cost-effectiveness, and comprehensive services.
We use high-purity tin bronze alloys (such as QSn10-1 and C93700) to ensure that the products possess excellent wear resistance, self-lubrication, corrosion resistance, and high strength. In sliding friction, the lead-containing material exhibits a low coefficient of friction and excellent self-lubricating properties, ensuring stable operation even in oil-free or low-oil environments. Simultaneously, the product boasts a tensile strength of 350–1035 MPa, is impact-resistant, and not easily deformed. It is non-magnetic and spark-free in explosion-proof environments, and its electrical and thermal conductivity surpasses that of most alloys, making it widely used in electrical connectors, heat dissipation components, and more.
In terms of production, We have introduced advanced large-scale centrifugal casting machines and industrial frequency induction furnaces, enabling the centrifugal casting of various specifications, ranging from a minimum of 50mm to a maximum diameter of 2m, length of 1.5m, and single-piece weight of up to 20 tons. After high-precision processing, the products have minimal pre-machining allowance on one side, achieving a utilization rate exceeding 95%, high dimensional accuracy, hardness, and a good luster. Furthermore, the company's engineering team can independently design molds to meet customized customer needs.
We have participated in major national projects, customizing a 15-ton ship propeller shaft for a Middle Eastern client, achieving short lead times and superior quality. The company has advanced laboratories and spectral testing equipment, is ISO9001 certified, provides full-chain services, and has a monthly production and sales volume of over 2,000 tons, ranking among the top in the country in terms of both production capacity and sales.
Our brass series products are renowned for their excellent strength and hardness. When subjected to heavy loads and impacts, its hardness effectively prevents deformation, ensuring the stability of mechanical connections. Although its electrical and thermal conductivity is slightly lower than pure copper, it still performs excellently in heat sink and electrical component applications. More importantly, our brass possesses superior low-temperature strength and resistance to frost heave, maintaining stable mechanical properties even in extremely cold outdoor environments, making it ideal for all-weather equipment. Furthermore, brass's good machinability and ductility make it easy to process into complex shapes and weld, significantly reducing your assembly and maintenance costs. In terms of corrosion resistance, it exhibits excellent rust resistance in air, fresh water, and seawater, with a beautiful golden color, combining practicality and decorative value.
For applications requiring even higher wear and corrosion resistance, our bronze series (including tin bronze, aluminum bronze, and tin-phosphorus bronze) are the "tough guys" of the industrial world. For example, national standard tin bronze (ZQSN555, SAE660) and American standard tin bronze (C55500, C93700) are the preferred materials for heavy-duty machinery sliding bearings due to their excellent friction reduction and wear resistance; while aluminum bronze (QAL9-4, C95500), with its high strength and impact resistance, demonstrates unparalleled durability in mining and marine engineering.
With its superior product quality, Our products have covered China and various countries worldwide, successfully serving numerous major national projects. Our brass bronze bushings and bearings are widely used in:
Hydropower and Marine Engineering: Utilizing the excellent seawater corrosion resistance of aluminum bronze and brass, they are used in turbines, gates, and marine equipment.
Heavy Machinery and Mining Equipment: Utilizing their high hardness and wear resistance, they withstand enormous impact loads, extending equipment maintenance cycles.
Automotive and Precision Manufacturing: Utilizing their good machinability and dimensional stability, they are used in critical components such as gearboxes and chassis.
