In automotive vehicle assemblies, control pins and weld locations are used in resistance welding. Silicon nitride has excellent mechanical, thermal, and wear resistant properties, which means it is not affected by the thermal shock and thermal cycling stresses produced during the welding process. These properties provide an improved life expectancy for silicon nitride weld pins.
