Silver Metcar Material

Metallized CarbonCorp.'sSilver Metcar is a silver impregnated, carbon-graphite material useful for electricalapplications that require low resistance, low voltage drop and low electricalnoise. The carbon-graphite in Silver Metcar provides self-lubricatingproperties and the pure silver provides high and constant electricalconductivity. The material is corrosion resistant, dimensionally stable and hasa heavy overload capacity. Additives to the carbon-graphite base materialimprove its self-lubricating properties in the dry atmospheres that occur athigh altitude and in space. Silver Metcar cannot melt or weld to another metalsurface because the carbon-graphite base material will not melt. It can besilver plated so that it can be soldered to metal parts such as leaf springs orconventional brush holders.

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

Ships, aircraft, rail systems and otherapplications that require low electronic interference use the Silver Metcarmaterial for dc motor brushes, non-welding electrical contacts and rotary slipring brushes or contacts. Applications include air traffic control radars,telecommunications systems and satellite communications systems.
