The role of copper in powder metallurgy is expanding

In recent years, powder metallurgy scholars pay more attention to materials with "nano" and "composite" characteristics, while ignoring the expanding role of basic materials and their processes in the field of powder metallurgy. Zhongwei, Qinhuangdao, found that copper has played a huge role in the field of powder metallurgy and will continue to promote its development. As early as 10000 years ago, copper was discovered and recognized as a unique metal. At first it was used for jewelry and other decorations. Natural copper blocks or copper bearing ores are used as raw materials, and the processing is very simple, that is, original cold processing. Back to 8700 BC, copper was used to make necklace pendants.

Through research and analysis, Zhongwei precisely 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 eroded verdigris as decorations for buildings, ceilings and outdoor installations.

Through a large number of studies, Zhongwei Precision has shown that copper is easy to form alloys with other elements, and is widely used to manufacture special-shaped forgings, castings and powder metallurgy products. For example, copper and nickel alloys have excellent seawater corrosion resistance; Tin can improve the strength and corrosion resistance of copper in solid solution; Zinc and copper alloys, namely brass powder, are used for water pipes, locks, valves and pipe fittings; Copper alloys containing nickel, tin, titanium, beryllium and cobalt are equivalent to high-strength steel in strength, and have high conductivity and thermal conductivity; Copper and copper zinc aluminum alloys are often used to produce flake gold powder; By adjusting the tin nickel composition, a specific color can be generated.

In the field of powder metallurgy, pure copper powder is used to produce electronic and thermal conductive 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. In addition, it is Fe Cu premix, dialysis and friction material components in the chemical industry.

To sum up, copper, as a basic material and its process, has been expanding in the field of powder metallurgy. For more information about copper in the field of powder metallurgy, please consult the zhongwei precision professional team!
