Silver Metcar Material

Silver Metcar Material

Metallized Carbon Corp.'s Silver Metcar is a silver impregnated, carbon-graphite material useful for electrical applications that require low resistance, low voltage drop and low electrical noise. The carbon-graphite in Silver Metcar provides self-lubricating properties and the pure silver provides high and constant electrical conductivity. The material is corrosion resistant, dimensionally stable and has a heavy overload capacity. Additives to the carbon-graphite base material improve its self-lubricating properties in the dry atmospheres that occur at high altitude and in space. Silver Metcar cannot melt or weld to another metal surface because the carbon-graphite base material will not melt. It can be silver plated so that it can be soldered to metal parts such as leaf springs or conventional brush holders.

To make the Silver Metcar materials, solid carbon-graphite base materials, in rings or blocks, are submerged in pure, molten silver and the silver is forced into the porosity of the carbon-graphite material using extremely high gas pressure. Most of the Silver Metcar grades contain approximately fifty percent silver by weight. X-ray inspection is used to ensure that each Silver Metcar part is uniformly impregnated with silver.

Ships, aircraft, rail systems and other applications that require low electronic interference use the Silver Metcar material for dc motor brushes, non-welding electrical contacts and rotary slip ring brushes or contacts. Applications include air traffic control radars, telecommunications systems and satellite communications systems.
