Characteristics and advantages of graphite lubrication

       I. Lubrication

       Graphite is a natural lubricant with excellent self-lubricating properties. Its advantage over molybdenum disulfide in the lubrication industry is that it does not produce a pungent odor at high temperatures. Its lubricating performance varies with the size of its flakes; larger flakes result in a lower coefficient of friction and better lubrication.

       II. Thermal shock resistance

       1. The smaller the elastic modulus of graphite, the better its elastic properties, the stronger its ability to buffer thermal stress, and the better its thermal stability.

       2. The smaller the coefficient of thermal expansion of graphite, the higher its thermal stability under the same conditions.

       Thermal shock resistance (also known as thermal stability or resistance to rapid heating and cooling) refers to the property of being able to withstand drastic temperature changes during use without being damaged, making it very suitable for high-temperature forging environments.

       3. Good electrical and thermal conductivity

       Its electrical conductivity is 100 times higher than that of ordinary non-metallic minerals, and compared with other common materials, it is 5 times that of stainless steel and 3 times that of carbon steel. Its thermal conductivity decreases as the temperature increases, and at extremely high temperatures, it tends to be in an adiabatic state.

       IV. High plasticity

       Graphite has excellent toughness and can be formed into very thin sheets, which meets the requirements for use in mold release agents.

       V. High Temperature Resistance

       Graphite has strong high-temperature resistance, with a melting point of 3850±50℃ and a boiling point of 4250℃. While the strength of most materials gradually decreases at high temperatures, the strength of graphite actually doubles at high temperatures, making it a preferred lubricant for forging and pressing.

       VI. Good chemical stability

       Graphite has excellent chemical stability and can replace non-ferrous or ferrous metals. In addition to being used as a forging lubricant, it is also widely used as a corrosion-resistant structural material.
