wear resistant Si3N4 ceramic trolley roller wheel
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
Properties of silicon nitride ceramic materials: GB material, various chemical components and composition of various components meet national standards, compact, no pores, no blisters, stable materials, superior performance, and high cost performance. In the cutting process, the knife will not be broken.
material stability is good: metal standard material, the material is completely rolled with the original aluminum ingot, the internal components are dense and uniform, the whole board hardness is uniform, mechanical properties are stable, high precision.High Precision Ceramic Network Resistor Substrate Plate
the surface quality is good: the surface of the material is bright and smooth, no obvious oxide layer, there is no obvious defects such as blisters, pores and black spots on the surface of ordinary alloy aluminum materials on the market.
Ordinary alloy aluminum plates are mostly used for recycling waste aluminum, which inevitably contains more impurity components, which not only makes the material performance decline, difficult to cut, and has a long processing cycle, and is unstable after the presence of impurities in the alloy. The surface of the product is very rough. In severe cases, cracks in the sand hole are generated, which affects the quality or accuracy of the product. The surface requirements for manufacturing some products are not high. From the perspective of cost, the product can also be used completely.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
