Graphite blank

Graphite blank

Product Description:

Graphite blanks have good chemical stability. Graphite is specially processed and has the characteristics of corrosion resistance, good thermal conductivity and low permeability. Widely used in the production of heat exchangers, sound-absorbing tanks, condensing devices, combustion towers, absorption towers, coolers, heaters, filters, and pump configurations. It is widely used in kerosene chemical industry, hydrometallurgy, acid and alkali production, synthetic fiber, papermaking and other industrial sectors, and can save a lot of metal materials. Suitable for castings, aluminum castings, molding and high-temperature metallurgical materials: Due to the small thermal expansion coefficient of graphite, it has the ability to change thermal shock and can be used as glass molds. When using graphite black metal castings, the dimensions are accurate, the appearance is smooth, the yield is high, and no handling or light processing is required, thus saving a lot of metal. Powder metallurgy processes such as cemented carbide are often used to make molds and sinter porcelain boats from graphite materials. Monocrystalline silicon crystal growth crucibles, regional refining vessels, support fixtures, touch heaters, etc. are all made of high-purity graphite. Other graphite can also be vacuum melted graphite insulation plates and base materials, high temperature resistance furnace tubes, rods, plates, grids and other components.
Conductive materials industry: used in the electrical industry to manufacture electrodes, brushes, carbon rods, carbon tubes, mercury locator anodes, graphite gaskets, telephone parts, TV picture tube coatings, etc.
Wear-resistant lubricants: Graphite is often used as a lubricant in rigid industries. Lubricating oil often cannot be used under high-speed, high-temperature, and high-pressure conditions, but graphite wear-resistant materials can slide at high speeds at temperatures of 200 to 2000°C without lubricating oil. Piston cups, seals and bearings made of graphite material are generally accepted in many configurations for conveying damping media that do not require lubricating oil. Graphite is also a good lubricant for many metal processing (wire drawing, tube drawing).
