silicon nitride guide pin , si3n4 location pin , ceramic guide pin
Usage: electrical industry, ceramic industry, oil industry, food industry, medical industry, chemical industry etc.
Characteristic: Resistance to strong acid, strong alkali, salt and gas of deleterious, long life, high hardness, resistance to wear, especially resistance to hydrofluoric acid.
Silicon nitride weld location pins are used in the metal forming industry. The location pins allow sheet metal parts to have nuts welded to them in precise locations. These pins make use of silicon nitride’s strength, wear resistance, resistance to molten metal slag, or a low affinity for various metals, and its electrical resistivity. Since the pins are electrical insulators, the welds are of a consistent high quality because there is no leakage of electrical current during the resistance welding. These parts are proven in a major automotive manufacturing plant. The performance to price ratio of Si3N4 weld location pins is 70 times of hat of steel pins.
