Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
Alumina abrasive polishing abrasive (also known as high alumina porcelain abrasive polishing abrasive) has a variety of shapes and specifications. This is manufactured to meet the needs of different workpieces. Since there are various shapes and specifications, it must have it. The reason, so, there must be a distinction in use to get the perfect surface treatment results. When selecting the size and shape of the alumina polishing abrasive, first of all, the shape and size of the workpiece to be processed, the presence of irregularities, the existence of holes, and many other conditions of the workpiece itself must be judged and analyzed. Then according to the characteristics of the workpiece, the corresponding abrasive polishing abrasive can be selected to better serve the surface treatment of the workpiece. The use of abrasive polishing abrasives, polishing abrasives, and polishing brighteners is closely related. Each abrasive material has Careful analysis and cooperation are required to obtain a good surface treatment effect, otherwise it will directly affect the surface grinding and polishing of the workpiece.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
