Pure graphite is a mineral form of the element carbon (atomic number 6) and its symbol is c. It forms in veins in metamorphic rocks as the result of the metamorphism of organic material included in limestone deposits. It is an extremely soft mineral at 1 to 2 on mohs' hardness scale. It is black and has a black streak. (streak is the color of a mineral when it is crushed to a powder). Its softness and streak make graphite useful in making f+leadf+ for pencils. Crystals are uncommon, but when they occur, they are found as rough, six-sided (hexagonal) flakes. It breaks into minute, flexible flakes that easily slide over one another. Mineralogists call this basal cleavage. This feature is the cause of graphite distinctive greasy feel. It is this greasy characteristic that makes graphite a good lubricant. Because it is a solid material, it is known as a dry lubricant. Graphite is the only non-metal element that is a good conductor of electricity. 25kg/bag;1 ton.Kraft bag.20ton/20fcl.

Natural graphite is used mostly in what are called refractory applications. Refractory applications are those that involve extremely high heat and therefore demand materials that will not melt or disintegrate under such extreme conditions. One example of this use is in the crucibles used in the steel industry. Such refractory applications account for the majority of the usage of graphite. It is also used to make brake linings, lubricants, and molds in foundries. A variety of other industrial uses account for the remaining graphite consumed each year. 25kg/bag;1 ton/ kraft bag;20 ton/20fcl or ad the customer request.

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. Wooden box
