The role of copper in powder metallurgy is expanding

In recent years, powder metallurgy scholars pay more attention to materials with "nanometer" and "composite" characteristics, while ignoring the expanding role of basic materials and their processes in the field of powder metallurgy. The discovery of copper has played an important role in the field of powder metallurgy and will continue to promote its development. Copper was discovered and recognized as a unique metal 10,000 years ago. It was originally used for jewelry and other ornaments. Natural copper or copper-containing ore as raw materials, the processing is very simple, namely the original cold processing. Dating back to 8700 BC, pendants were made of copper.

Through research and analysis, the new material of guangdong dahong found that copper has excellent thermal and electrical conductivity, as well as good corrosion resistance and mechanical properties, and copper is easy to be processed into complex shapes and filaments. Architects often use its bright red color and its corroded bronze green to decorate buildings, ceilings and outdoor installations.

Through a lot of research, it is shown that copper is easy to form alloy with other elements. For example, copper and nickel alloys have excellent resistance to seawater corrosion. Tin can improve the strength and corrosion resistance of copper in solid solution. Zinc and copper alloys, known as brass powders, are used in pipes, locks, valves and fittings. Copper alloys containing nickel, tin, titanium, beryllium and cobalt are as strong as high-strength steel and have high conductivity and thermal conductivity; Copper and cu-zn-al alloy are often used to produce flake gold powder. By adjusting the tin-nickel composition, specific colors can be produced.

In the field of powder metallurgy, pure copper powder is used to produce electronic and heat-conducting parts. Copper alloys containing tin, zinc, nickel, or iron are widely used in MIM auto parts, lawn park equipment, MIM mobile phone accessories, MIM building materials accessories and MIM smart wear. Copper powder is mostly used in self-lubricating bearings, and is also used in pre-mixing of fe-cu, dialysis and friction material components in chemical industry.

To sum up, copper, as the basic material and its technology, has been expanding in the field of powder metallurgy. More about copper in the field of powder metallurgy, welcome to consult the professional team of guangdong dahong new materials for your answer!
