Molded graphite
Molded graphite materials we supplied are divided into two series: fs series /fb series . They have high anisotropy. The materials provide extremely wide characteristics such as mechanical strength, friction and conductivity, which can be further enhanced by impregnation with resins or metals. Special materials can be processed by pressing components directly close to final sizes. The press-to-size-technology reduces the cost of machining in large quantities.
Graphite material is an especially fine grain, dense, isotropic graphite. Isostatic press graphite has many good characteristics such as high strength, excellent thermal shock resistance to high temperature and oxidation, low specific resistance, good anticorrosion, ease of precise machining, high purity, and also have the merits of large size and good isotropy.
Product description:
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 8.8ã103kg/m3, graphite 2.2ã103kg/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 1100â 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.
