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. Copper content:25-95 Fineness:200-800 mesh

Different specifications: 1.Superfine graphite rod; 2.Fine extruded graphite rod; 3.Medium extruded graphite rod; 4.Large graphite rod

A crucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot. Graphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock. Especially graphite crucible is ideal for the melting of aluminum, copper and other metals. Quartz crucible has the advantages of high purity ,high temperature resistance, with big size ,good thermal insulation, economization on energy ,quality stability etc. Fused quartz crucibles are used in the manufacture of silicon metal for semiconductor wafer applications and polysilicon. In order to produce high quality wafers, starting materials are added to a crucible heated to high temperatures and pulled from the melt as a single crystal. Fused Quartz is one of the few materials that can combine the high purity and high temperature properties required for this process. GW offers graphite crucibles & Ceramics (Quartz) crucibles in different sizes and types. Whenever you need crucibles, just feel free to contact us, and we will reply you in a shortest time.
