Copper Bushings Essential Components for Versatile and Customizable Mechanical Applications

1) Description of Copper Bushing

Copper bushings are tubular components made of copper alloys formed through metallurgical processes.

They are produced via casting, forging, or machining, with common alloying elements including tin, aluminum,

and zinc. During the manufacturing process, strict control is exercised over the composition ratio and microstructure,

endowing the products with specific mechanical properties. They are indispensable basic components

in the field of mechanical manufacturing.

2) Feature and Advantage of Copper Bushing

a) Highly Adjustable Composition: The composition ratio of copper alloys can be flexibly adjusted according to

different application requirements. For example, increasing the tin content can enhance wear resistance,

while adding aluminum can improve corrosion resistance, meeting diverse industrial application scenarios.
b) Diverse Forming Processes: Various processes such as centrifugal casting and sand casting can be employed,

catering to different precision and production volume requirements. Centrifugal casting can produce copper bushings

with a dense microstructure and excellent performance, while sand casting is more suitable for small - batch production

of customized, complex - shaped components.
c) Controllable Cost: Compared with components made of some rare metals, copper alloys are sourced widely,

and the production processes are mature. This enables effective cost control while ensuring performance.

3) Working Principle of Copper Bushing

In metallurgical manufacturing, copper bushings function based on their internal microstructure.

The hard phases in the alloy provide wear resistance, while the soft phases offer lubrication. When paired with a shaft,

a microscopic lubricating layer forms on the surface of the copper bushing during friction, reducing the coefficient of friction.

Additionally, it can adapt to slight shaft eccentricity and vibrations through its plastic deformation.

4) Application of Copper Bushing

In the metallurgical industry itself, copper bushings are used in equipment such as blast furnace burden distributors

and continuous casting machine roller tables. In the field of mining machinery, they are applied in components

like the eccentric shaft bushings of crushers and the hollow shaft bushings of ball mills. In these scenarios,

equipment operates under heavy loads and harsh environments. Copper bushings ensure stable equipment operation

with their customizable performance.
