Pure copper plate is a higher copper content, generally pure copper is the mass concentration of copper is not less than 99.7%, very little miscellaneous quality oxygen copper, dark purple appearance, so it is also called copper. Oxygen free copper alkali brittle state, high conductivity, production and processing properties, welding properties, corrosion resistance and ultra-low temperature properties are good.
Pure copper: The key as conductive, heat transfer, corrosion resistant electronic devices, such as power lines, cables, conductive screws, housing and a variety of hoses, etc. Can also be used as a structural material application, such as making electrical switches, sealing rings, bolts, nozzle and a variety of hoses; Also used for less critical electrical conductivity components.
Processing properties of red copper:
Copper smelting and forging process performance: choose casting furnace melting or DC core induction heating furnace melting; The selection of copper mold or iron mold casting, melting process should be as far as possible to reduce the source of steam, and the application of forged burned wood carbon as a solution, can also use phosphorus as a deoxidizing agent. The whole casting process is carried out under N2 protection or covering ash. The proposed forging temperature is 1150-1230℃, and the linear shrinkage rate is 2.1%
Copper molding processing performance: has good cold, heat treatment performance, can be used in a variety of traditional production process, such as Lashen, injection molding, deep drawing, bending, fine pressing and stamping. During heat treatment, the heating material atmosphere should be manipulated to make it slightly reductive. The heat treatment temperature is 800-950℃.
Performance of welding method of red copper: easy to solder, tin welding, can also carry out gas shielded welding, shine welding, electron beam welding and gas cutting, but can not carry out point contact butt welding and arc welding.
Turning production and machinability of copper processing technology performance: copper drilling technology for 20%.
