Product Description

Tungsten (W) is derived from Wolframite (Fe,MnWO4) and is widely used in the filament industry for lamps & electronic contacts, for hardening metals and as a dry high-temperature lubricant. We sell Tungsten as gauze, foil and bars, and can source regular and plated wire to a range of certified purities. We actively trade across a network of sources so that we can offer you, the customer, the best price and the best service.ApplicationsPrimary applications that demand Tungsten include:Tungsten as a high density material (19.2 g/cm3) for use in dynamic balancing, counterweights and flywheels.Tungsten for radiation shields and x-ray targets.Tungsten wire which is drawn into a fine filament for use in lighting, electronic devices and thermocouples.Tungsten powders for chemical applications such as dyes, pigments, catalysts, cathode ray tubes and x-ray screens.Tungsten as an additive for high temperature resistant alloy
