Overview
AgNi has better resistance to welding and arc erosion than that of Ag or FAg. Due to the increase of nickel content with high melting point phase. All AgNi materials have good processability and are easy to weld. Less material transfer under DC current making and breaking, AgNi is an environmentally friendly material.
Range of applications
AgNi products are widely used in low-voltage switchgear. Such as relays, miniature contactors, light switches, temperature controllerss, protection switches (with AgC, AgZnO etc. to form asymmetrical matching contacts).
