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
Product description All high purity molded pressed graphite have individual properties that will help you to choose the perfect grade that best suits your needs. Molded pressed graphite provides an extremely wide range of properties in terms of mechanical strength, friction, density, hardness and conductivity, which is even further enhanced by impregnation with resin or metal. Due to their fine grain size and homogeneous structure, it can often replace isostatic graphite if dimensions is not taken into consideration. Features 1.Good machinability Compared with metallic materials, the bulk density of graphite is lower. It has excellent mechanical machining properties. 2.Strong thermal stability It is possible to be used even at 3000 in inert atmosphere or more. 3.Low expansion ratio Low thermal expansion ratio will ensure dimensional stable, even rapid change in temperature. 4.Excellent chemical resistance Graphite has good chemical stability at room temperature. Resistance to acid, alkali, and organic solvents. 5.Excellent electrical conductivity and thermal conductivity With strong thermal resistance, which means graphite is the ideal material for certain applications like heating element.
Product description Iso-molded graphite, also named isostatically pressed graphites or isostatic graphiteisotropic graphite. It is produced by the method of cold isostatic pressing (cip). Graphite is iso-statically pressed is because it allows for uniform properties in all grain directions. This differs from extruded which is pushed through a die and has varying properties in different grain directions. Iso-molded graphite is used for specific applications where uniform is required. Djx graphite obtain a high finished product yield rate due to our unique process and quality control, this enable us to produce high quality consistent isotropic graphite.

Djx specialized in carbon graphite materials and products for more than twenty years, we are confident to provide you high quality products with the most reasonable price, please join us to enjoy our quality and services. Djx supplies graphite plate for spd surge protection device with various sizes, customerized products are available depending on your pictures and drawings, we will recommend the most suitable graphite material for you, please contact us for more details. Based on the disadvantage of traditional gap surge protector (spd), and combined with the material characteristics of graphite and thompson gas discharge theory, a large scale of experiments on the new type of graphite gap spd were completed by open circuit voltage wave generator and icgs impact system. The results show that, after the high voltage trigger capacitance device was added to the new type of graphite gap spd, every gap was triggered step by step so that the voltage protection level was reduced. At the same time, the graphite gap spd is better than traditional gap spd on time delay characteristics, and is able to achieve the arc extinction requirements before the power frequency voltage dropped to zero. In addition, graphite belongs to non-metal materials; it won't produce plasma under high temperature, which can improve the stability of device and delay aging.

Product Introduction Copper-coated molybdenum disulfide, chemical formula CuMoS2, it is a kind of coated metal powder with the same appearance of pure copper. Copper-coated molybdenum disulfide is an important solid lubricant, it is especially suitable for high temperature and high pressure conditions. Due to low friction coefficient of molybdenum disulfide, the frictional resistance generated between the equipment is low, so it can save the power consumption. In addition, molybdenum disulfide has features of moisture and water proofing, alkaline resistance, acid proofing etc.. The plastic or powder with molybdenum disulfide can be made into all kinds of mechanical parts, this can save a lot of non-ferrous metals.The solid lubricant of copper-coated molybdenum disulfide is really a new type lubricant material accords with More-Fast-Better-Economizing. Copper-coated molybdenum disulfide has the feature of diamagnetism, it can be used as linear photo-conductor or semi-conductor to show P type or N type conductivity, it has the function of rectification and transduction. Molybdenum disulfide can also be used as catalyst for dehydrogenation of complex hydrocarbon. Copper-coated molybdenum disulfide is also be honored as The King of Advanced Solid Lubricant. Molybdenum disulfide is a kind of solid powder made from natural molybdenum concentrate powder after chemical purification and the change of molecular structure. The original color is black with a little bit silver gray, it has metallic luster and soapy feeling for touching, insoluble in water. It has the advantages of good dispersibility and non-caking, it can be added into the grease to form non-cohesive colloidal state, this increase the lubricity and extreme pressure property. It is also suitable for the mechanical working condition of high temperature, high pressure, high running speed and high load, so it can extend the service life of the equipment. After being coated by special techniques, copper-coated molybdenum disulfide also has the stability and lubricity of copper at the same time, it is absolutely a kind of good new material.
