product description
Shed Shape Solid Contact Rivet
Product Material
Ag /Fag
General Description
Silver and fine grain silver(FAg)possess very high electrical and thermal conductivity,low and stable contact resistance,and good workability.For silver resistance to arc erosion and contact welding are limited,mechanica strengthis low,Due To the small quantity of nickel in the fine grain silver,resistance to arc erosion and mechanical strength are higher than that of silver.
Application Scope
Widely used in low current devices,such as relays,timers,auxiliaryt switches for household appliances(FAg),control switches(FAg).

Blind Hollow Shank Tungsten Points
PRODUCT MATERIAL
Wu/FE
General Description
The Tungsten points are arc resistance, redectory,and less current consumption when the metal contact on surface,strong on-off current capability, good wear properties and dynamic performance hit.And its cheaper than any other metal or alloy material.
Application Scope
Mainly used in the electric products such as automobiles, motorcycles, electric horn, magneto etc.
