Silver Nickel

Scope

This information refers to silver nickel wires, profiles and contact tips manufactured by blending of silver and nickel powder, compacting,sintering, extruding and drawing or rolling to final dimension.

DESIGNATION OF STANDARD COMPOSITIONS

the Ni content of the material is designated in weight percentage.
Standard gradations are 10, 15, 20%.

Applications

switches for domestic applications, main switches
switches for domestic application, auxiliary switches
contactors of switching currents upto 100A
miniature circuit breakers, circuit breakers (asymmetrical combination with AgC)
power line relays, automotive relays

CHARACTERISTICS

reliable anti-welding properties for switching currents upto 100A
low contact resistance (nearly constant throughout the life time)
low arc erosion for switching current upto 100A
good arc migration and arc extinguishing properties
good formability, can be welded directly

MICROSTRUCTURE

The Ni particles are deformed along the direction of extrusioii into fibres

AgNi10
Longitudinal Sectional (parallel to the diretion of extrusion)
