Coiled horizontal helix tungsten wire filaments

Coiled Filaments

Single or 3-strand coiled tungsten filaments, 0.5mm diameter wires.

Tungsten has the highest melting point and lowest vapour pressure of all metals, and at the temperatures over 1650°C has the highest tensile strength. It has excellent corrosion resistance and is attacked only slightly by most mineral acids.

Tungsten is the most useful material used in vacuum evaporation technique, due to its special properties and cost factor.
