Copper 663 is a type of tin bronze, with its main components including tin (Sn) 5–7%, zinc (Zn) 5–7%, lead (Pb) 2–4%, and the remainder being copper (Cu). This alloy exists in various forms such as powder, sheet, and rod, and is commonly used in situations involving medium speed and medium loads.

Copper 663 exhibits good wear resistance and corrosion resistance, along with ease of processing, making it excel in casting performance and airtightness. Therefore, it is often used to manufacture wear-resistant and corrosion-resistant parts that operate under higher loads and medium sliding speeds, such as bearing shells, liners, cylinder sleeves, piston clutches, pump part pressure covers, and worm wheels.

Overall, Copper 663 is a copper alloy with excellent physical and chemical properties, widely applied in various applications that require high strength, high wear resistance, and high corrosion resistance.

Self-lubricating sintered copper sleeve 663 material is a type of material with excellent self-lubricating and wear-resistant properties, widely used in various mechanical equipment. Here is a detailed introduction to the self-lubricating sintered copper sleeve 663 material:

Material Composition and Characteristics: The self-lubricating sintered copper sleeve 663 mainly consists of a copper matrix and other alloy elements, manufactured through a special sintering process. This material has good self-lubricating properties, capable of forming a lubricating film during friction, reducing the friction coefficient and wear, enhancing the efficiency and lifespan of the equipment. It also boasts excellent high-temperature resistance, corrosion resistance, and impact resistance, able to adapt to various harsh working environments. Application Areas: The self-lubricating sintered copper sleeve 663 material is extensively used in various mechanical equipment, such as metallurgical machinery, mining machinery, hydraulic machinery, automobiles, construction machinery, agricultural machinery, etc. In these devices, the copper sleeves are typically used in critical parts like bearings, sliders, and guide rails, playing a role in bearing loads, transferring motion, and reducing friction. Advantages and Benefits: Self-lubricating performance: Eliminates the need for an additional lubrication system, lowering maintenance costs and enhancing equipment reliability. Wear resistance: Capable of enduring high loads and prolonged friction, extending the service life of the equipment. High-temperature and corrosion resistance: Can work stably in harsh environments like high temperature and high humidity, resistant to deformation or damage.

Sintering Bronze Bushing: An Insight into Materials and Processes
Sintering is an innovative technique widely utilized in materials science, particularly in the manufacturing of bronze bushings—a critical component in various mechanical systems. This article delves into the essence of sintering, its operational mechanics, the specific application to bronze bushing types, and the materials involved, with a focus on the benefits of this sophisticated process.
What is Sintering? A Definition
Sintering is a process that involves the consolidation of powdered materials, typically metals or ceramics, through heat and sometimes pressure. The particles in the powder blend fuse at temperatures below their melting points, creating a solid, coherent mass. This method is crucial in manufacturing complex shapes and sizes, offering a level of precision and efficiency unattainable through traditional means.
How Sintering Works
The sintering process unfolds in stages, starting with the powder being compacted into the desired shape, often under high pressure. The compacted ‘green’ part is then heated in a controlled atmosphere to a temperature where the material’s particles bond without melting entirely—this is known as the sintering temperature. During this phase, the particles diffuse across the boundaries, fusing together to form a solid piece.
Sintered Bronze Bushing Types and Process
In the context of bronze bushings, sintering is particularly advantageous. Sintered bronze bushings are manufactured from bronze powders, which are sintered into a cohesive body and then impregnated with lubricants to enhance their operational characteristics. These bushings are essential in numerous applications, providing a self-lubricating, maintenance-free component that is crucial for reducing friction and wear in machinery.

The types of sintered bronze bushings vary, including flanged, cylindrical, and custom-made bushings, each tailored to specific operational requirements. The process ensures uniformity in material properties, precise dimensions, and a structure that can withstand demanding conditions.
Brass and Bronze in Sintering
While bronze is the primary focus, it’s essential to distinguish it from brass, another commonly sintered material. Bronze is an alloy primarily of copper and tin, whereas brass is a blend of copper and zinc. Both materials are conducive to sintering, but bronze, especially in bushings, offers superior wear resistance and load-bearing capacity, making it more suitable for high-stress applications.
Bronze Materials Used in Sintering
The bronze used in sintering typically consists of a blend of copper, tin, and often additional elements like lead or phosphorus, enhancing certain properties. For example, leaded bronze is favored for its excellent machinability and compatibility with lubricants, whereas phosphor bronze is renowned for its superior strength and corrosion resistance.
Benefits of the Sintering Bronze Bearing Process
The sintering process offers numerous benefits for bronze bearing production:

Complex Shapes and Sizes: Sintering allows for the creation of complex and precise shapes that are difficult or impossible to achieve with other manufacturing methods.
Material Efficiency: There is minimal material wastage, as the powder can be precisely controlled and any excess can be recycled.
Enhanced Properties: Sintered bushings exhibit uniform material characteristics, high strength, and reduced porosity, enhancing their performance and longevity.
Cost-Effectiveness: The efficiency of the process and the reduction in material waste contribute to cost savings, particularly for high-volume production.
Customization: The versatility of sintering enables the customization of bushings to meet specific requirements, offering tailored solutions for various applications.

In conclusion, sintering is a cornerstone technique in the production of bronze bushings, providing an array of benefits from material efficiency to enhanced mechanical properties. This advanced manufacturing process underscores the continual evolution of materials science, offering innovative solutions in a myriad of industrial and mechanical applications.
