Coated with Copper Copper Coated Graphite Powder
is a kind of new material produced by our factory, its specific gravity is higher than graphite and lower than copper, it overcomes the disadvantages of the mechanical mixing powder in the old technology, such as difficult to mix evenly and easy to form segregation due to big density difference ( copper 8.8×103kg/m3, graphite 2.2×103kg/m3) and bad dispersibility of graphite powder. At the same time, carbon and copper interface can only be connected by mechanical interlock, the bonding strength between the interfaces is low, which causes unstable product quality. For graphite and copper of high temperature infiltration, even when the temperature is up to 1100℃ the wetting angle is 140°, it is very difficult for graphite to form evenly suspending distribution state in copper solution, and easy to have segregation.
The copper coated graphite powder produced by our company is to make the graphite surface to be coated with one layer of continuous copper first, so the graphite distribute evenly between the copper. It is easy for copper to form three-dimensional grid structure, the interface bonding strength is high, which improves the product quality, it can be widely used as adding material in the production of motor brush, self-lubricating bearing, spray, liquid metallurgy material and so on.
Fineness and copper content of DJX copper coated graphite powder: Fineness: 200-800 mesh Cu content: 25%-95% Note: fineness and copper content can be adjusted according to customer’s requirement. Applications of copper coated graphite powder : DJX copper coated graphite powder is popular for Powder Metallurgy
and machinery, it also can be used for : ♦spraying materials ♦ liquid metallurgy materials ♦ self-lubricating bearing ♦Carbon Brush
♦pantograph slide plate ♦ electrical contact ♦lead frame of integrated circuit ♦collecting ring of the generator ♦ other electrical parts
Compared with traditional graphite powder, DJX copper coated graphite powder has the advantages stated blow:
