Wire - Tungsten (25μm)

Tungsten Wire

Tungsten (74 W183.85)

The metallic element tungsten is not found free in nature, but in several ores. Tungsten is steel-grey to tin-white in colour and, when very pure, can be forged, spun, drawn, and extruded. Impure tungsten is very brittle and difficult to work. Tungsten is very resistant to corrosion and stable in dry air at room temperature. Tungsten’s melting point exceeds that of all other metals and it has the lowest vapour pressure. At temperatures over 1650°C, tungsten has the highest tensile strength. It has excellent corrosion resistance and is affected only slightly by most mineral acids.

The following is a list of Tungsten Wire we can offer in 99.95% pure.

In some cases we can offer as little is 1m in length. Please contact us with you requirement.
