Key Features of Brass Bushings

Material Properties
- Typically made from C360 (free-machining brass), C932 (bearing bronze), or other brass alloys.
- Offers good corrosion resistance, low friction, and excellent machinability.
- Softer than steel, making it a sacrificial component that protects more expensive parts.
Self-Lubricating Options
- Some brass bushings are oil-impregnated (sintered brass) for reduced maintenance.
- Others may have graphite plugs or PTFE coatings for dry lubrication.
Common Types
- Plain cylindrical bushings – Simple sleeves for general use.
- Flanged bushings – Have a flange to prevent axial movement.
- Thrust washers – Handle axial loads in rotating assemblies.
- Oilite bushings – Porous, oil-retaining brass bearings.

Key Characteristics of High-Quality Copper Sliding Sleeves:

Excellent Wear Resistance: Bronze itself has good wear resistance, and with the addition of solid lubricants, the wear resistance of the oilless bronze guide bushing is further enhanced, which can significantly extend the service life of the parts in high-wear applications. Self-lubrication: It can work without the need for additional lubricants, eliminating the trouble of regular lubrication and maintenance, reducing maintenance costs and improving equipment operation efficiency. High Load Capacity: It can withstand relatively high loads and is suitable for applications in heavy machinery and equipment. Good Corrosion Resistance: Bronze has good corrosion resistance in many environments, so the oilless bronze guide bushing can maintain stable performance in corrosive media such as the atmosphere and fresh water. High Precision: It can be processed to high precision to meet the requirements of high-precision equipment for the fit and movement accuracy of parts.

ZCuSn5Zn5Pb5

Casting: ZCuSn5Zn5Pb5 has good casting properties and can be formed by various casting methods such as sand casting, permanent mold casting, and pressure casting, enabling the manufacture of various complex-shaped parts. Machining: Due to its moderate hardness, it has good machinability. It can be processed by mechanical processing methods such as turning, milling, drilling and grinding to produce part surfaces and dimensions that meet different precision requirements. Heat Treatment: In order to improve the structure and properties of the alloy, appropriate heat treatment such as annealing and solution treatment can be carried out. Annealing can eliminate casting stress and improve the toughness and workability of the alloy; solution treatment can improve the strength and hardness of the alloy.

C86300

Processing Characteristics Casting: C86300 has good casting performance and can be easily formed by various casting methods, such as sand casting, die casting and investment casting. It can produce complex-shaped components with high dimensional accuracy and surface quality, meeting the needs of different application scenarios. Machining: The alloy has good machinability and can be processed by turning, milling, drilling, grinding and other machining methods. It can obtain high-precision components with good surface finish, which is convenient for subsequent assembly and use. Welding: C86300 has certain weldability and can be welded by appropriate welding methods. However, in the welding process, it is necessary to pay attention to controlling the welding parameters to avoid problems such as cracks and porosity and ensure the welding quality.

ZCuSn10Pb1.

Physical Properties Density: The density is about 8.8g/cm³. With a relatively large density, the weight factor needs to be considered in the design and use process, especially in some occasions where the weight is strictly required. Melting Point: The melting point is generally about 900℃ - 950℃. Compared with pure copper, its melting point is reduced, which is beneficial to the melting and forming in the casting process. Electrical and Thermal Conductivity: Due to the high copper content, ZCuSn5Zn5Pb5 still has good electrical and thermal conductivity and has certain application potential in some occasions where good electrical or thermal conductivity is required.

ZCuSn10Pb5.

Main Elements: The main alloying elements in ZCuSn10Pb5 are tin (Sn) and lead (Pb). It typically contains about 10% tin and 5% lead. The high tin content provides good corrosion resistance and wear resistance, while lead helps to improve the alloy's machinability and lubricity.

ZCuPb10Sn10.

Mechanical Manufacturing：It is suitable for manufacturing heavy-duty and high-speed wear-resistant parts, such as bearings, gears, and worm wheels. For example, in industrial machinery, the bearings and gears that need to work under high load and high speed can use ZCuPb10Sn10 to improve service life and reliability.

ZCuPb15Sn8.

ZCuPb15Sn8 has good casting performance and can be easily formed by various casting methods, including sand casting, die casting and investment casting. This allows for the production of complex-shaped components with high dimensional accuracy. Machining: Although it has a certain hardness, the alloy has good machinability. It can be processed by turning, milling, drilling and other machining methods to obtain components with high precision and good surface quality. Heat Treatment: Appropriate heat treatment processes, such as annealing and quenching, can be carried out on ZCuPb15Sn8 to further improve its mechanical properties and microstructure, meeting the specific requirements of different applications.
