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.
Why would the biggest connector company in the world design and build the first fully functional 3D-printed motorcycle? To show TE Connectivity's engineers what the technology can really do in making working load-bearing production parts, and free up their thinking when approaching design problems.
The enhanced ST8 includes new functionality designed to help users accelerate design speed and improve the user’s ability to leverage synchronous technology. The update offers greater flexibility in choice of platform and purchasing options, according to the company.
“How can European standards affect me, especially since I only use machines built in the US?” This is a common question, and one way to answer this is to look at how machine safety is enforced, where the information comes from, and how well you can prove you followed the regulations.
