Tantalum Wire and Ribbon is corrosion resistant and has good thermal conductivity. Some of its uses is in the manufacture of heating elements, vacuum tubes and other high temperature parts

Copper wire has an extremely high electrical conductivity making it highly suitable for electrical connections and thermal conductivity applications.

Stainless Steel wire does not stain, corrode or rust easily as ordinary steel wire.

Nickel wire provides good corrosion resistance. It is most suitable for use in electronic components, temperature sensors, electrical resistance thermometers and other electrical applications.

Inconel wire is a nickel-chromium alloy wire for applications requiring good resistance to oxidation and corrosion at high temperatures.
