Bronze is a versatile copper alloy valued for its strength, corrosion resistance, and durability. It’s often used to manufacture special components designed to perform reliably under complex or demanding working conditions across various industries. Each bronze part is custom-engineered to match the specific requirements of the equipment, ensuring high precision and consistent performance.
A variety of bronze alloys are available to meet different application needs, including C93700, C94100, C93800, and C95800.
| Material No. | Category | Core Properties | Typical Applications |

|
|
Aluminum Bronze (Corrosion-Resistant Type) | • High strength and corrosion resistance • Excellent mechanical stability • Suitable for chemical and marine environments |
Applied in piping components, chemical equipment, and medium-load bearing shells. |
|
|
Tin Bronze (High Machinability Type) | • Strong wear resistance and durability • Stable performance and excellent machinability |
Suitable for heavy-load bearing shells, compression parts, and large water pump components. |
|
|
High-Strength Aluminum Bronze | • High strength and hardness (tensile strength 800–950 MPa) • Excellent heat and corrosion resistance • Stable at 300–350 °C |
Commonly used in marine and offshore engineering parts, such as propeller components, pump impellers, and heavy-duty sliding bearings. |
Bronze alloys are used across multiple industries for their strength, corrosion resistance, and ability to perform under demanding conditions:
- Propellers: C63000 aluminum bronze combines seawater corrosion resistance with high strength, helping slow down corrosion and handle hydrodynamic loads that affect propulsion systems.
- Propeller Parts: C95200 aluminum bronze, with a tensile strength of 450–690 MPa and an elongation rate of 13–29%, is also used to produce propellers and other parts exposed to complex stress and constant vibration.
- Marine Shafts and Connectors: C95400 aluminum bronze is used to manufacture ship shafts, nuts, rudders, and hull connectors, for its ability to resist seawater corrosion and retain mechanical stability under marine conditions.
- Engine Parts: C63000 aluminum bronze offers excellent heat and pressure resistance, making it ideal for engine connectors and sealing parts that must perform under extreme conditions.
- Heavy-Duty Parts: C95400 aluminum bronze is used to make gears, bearings, screws, nuts, sleeves, and sealing rings. This alloy performs well in high-stress and high-wear conditions, keeping the wear parts strong and stable for a long service life.
- Wear Parts: C95200 aluminum bronze, with a Brinell hardness of 110–230 HB, is usually chosen to manufacture bearings, bushings, and gears that face constant friction. It is also used in automotive engines and other moving parts that need good wear resistance and fatigue strength to ensure reliable performance.
- Bushings: C86300 manganese bronze bushings have good strength, durability, and wear resistance. These wear parts are made for mining machines that work under heavy loads or in rough environments. Since they are self-lubricating, they can run smoothly even when regular oiling or maintenance isn’t possible.
- Copper Slippers: Copper slippers are used in demanding mining equipment because they conduct electricity well, resist wear, and don’t create static, sparks, or magnetic fields. This helps keep the machines safe and reliable.
- Spherical Bearings: C95800 tin bronze is used for bearings that need both strength and corrosion resistance. Its mix of copper, tin, nickel, and aluminum keeps it stable at high temperatures and helps it resist wear and fatigue over time.
- R&D Capability
We handle every production stage independently, from the development and casting of bronze wear parts to machining and quality inspection. This allows us to have full control over product quality and ensures that each process is backed by our proprietary know-how and patented technologies.
- Industry Experience
Backed by more than 40 years of experience, we specialize in bronze wear parts for wind power, mining, hydropower, marine, and oil extraction equipment. Our product catalog includes bronze and steel bearings, bushings, and other wear components. We have long-term partnerships with several Fortune 500 companies within these industries.
- Production Strength
Our workshop is equipped with 20 advanced five-axis machining centers from MAZAK and MAKINO, along with 35 imported turning and milling machines. The 5,000 m² temperature-controlled facility is operated by experienced CNC technicians who make sure every part is machined with accuracy and consistency.
- Quality Control and Certifications
We manage every step of production in-house, following ISO9001 and CCS quality standards to ensure consistent results. Our CNAS-accredited laboratory (CNAS L5937) and skilled inspection team handle all testing and verification, including material composition, hardness, tensile strength, and microstructure, along with non-destructive tests such as UT, PT, and VT. All procedures comply with GB, ASTM, ISO, JIS, and YS standards.
Bronze eccentric bushings are made from high-lead bronze alloys such as ZCuPb10Sn10, ZCuPb15Sn8, and ZCuPb20Sn5. These alloys provide excellent self-lubricating, anti-seizing, and wear-resistant properties, allowing stable performance even under strong impact and heavy dust exposure. The wear resistance can also be enhanced through customized designs to meet the demands of abrasive working conditions.
Bronze nuts and slippers are produced from high-strength copper-based alloys that offer excellent resistance to seawater corrosion. These alloys retain their mechanical integrity and surface stability over time, making them well suited for continuous operation in marine, humid, or chemically active environments.
High-precision bushings are manufactured through centrifugal casting, five-axis CNC machining, and polishing. With strict quality control and CNAS-certified testing, tolerance accuracy reaches ±0.025 mm and surface roughness Ra ≤ 0.8 μm, meeting the standards required for CNC systems.
Yes. Bronze bearings are made following ISO and DIN standards for materials, precision, and surface finish. They can be used with equipment that is manufactured under international requirements, ensuring consistent performance across different applications.
Bronze nuts, sliding bearings and other wear parts can be manufactured according to customer drawings and specifications. Each wear part will be manufactured with micron-level precision to match specific design or size requirements in different industries.
