Manufacturer supplying high quality copper grain with 99.9995% purity made in china

Product Description
  • Ultra high-pure copper particles is a form of copper that has a purity of 99.9999%. In order to remove impurities from copper ore, it undergoes two processes, smlting and electrorefining. As an excellent conductor of electricity and heat, copper  particlesis is often used to make copper wire. The pliable nature of copper makes it an excellent choice for electrical and audio wires, which must be thin and flexible. 

Product advantages

The sample description of copper grain application:

  • Cu granules are an ideal metal evaporation material for PVD. Meanwhile, they can also be used for high purity metal alloy smelting, high purity metal compound preparation, crystal preparation and other fields. Copper rod is most widely used and has the largest consumption amount in electrical and electronics industry, taking more than half of the total consumption.

How to produce


  • First, our workers cut,cleanout the 99.95% pure copper material ,and then put them into the equipment  which can purify 99.99995% pure copper from 99.995% pure copper material. In the purification process,our professional workers can control the electricity,the rate of circulation and temperature.And they also can put additive into the electrolyte.
  • In short ,We mainly adopt electrolytic refining method which is used to obtain high purity copper.The pocess is highly purified of electrolyte with a higher purity of copper electrolysis again.
  • Depending on the type of electrolyte, the system can be divided into three kinds. First, the copper sulfate solution;Second,copper nitrate solution;Third,copper sulfate solution and copper nitrate solution.
