Si3N4 Bearing Ball Of Ø17.4625 mm With G5/G10 Precision Grade
At present, Zhongxing Shiqiang Technology (Tianjin) Co., Ltd. has our recipe advantage (highly purified, submicron powder with an alpha phase of more than 92%), sintering advantage ( GPS (Gas pressure) and HIP (Hot isostatic pressure) sintering technology) and mature grinding technology ( abundant producing experiences). Besides, our company had established massive and automatic production lines of ceramic balls, which means production increase. Our company can produces HIP-Si3N4 ceramic balls with Precision Grade of G5, welcome your inquiry.
Propertis advantages of HIP-Si3N4:
High hardness and high fracture toughness, high strength and good magnetic and electric insulation, excellent wear resistance, corrosion resistance and thermal shock resistance.
