High hardness and high temperature resistance of silicon nitride positioning pin ceramics

Silicon Nitride Ceramic High Performance Ceramic Positioning Pin

Product Overview

The silicon nitride ceramic positioning pin is a high-performance ceramic positioning pin, which has extremely high hardness, high thermal shock resistance, electrical insulation, high temperature resistance, high tensile strength and compressive strength, and reduces cold welding spatter. In the field of welding positioning pin products, the precise matching and positioning of the welding plate and the welding nut in projection welding at a high temperature of 800 degrees Celsius is no different, and the effect is better than other materials.
