contactTungsten is a greyish-white lustrous metal, which is a solid at room temperature. Tungsten has the highest melting point and lowest vapor pressure of all metals, and at temperatures over 1650°C has the highest tensile strength. It has excellent corrosion resistance and is attacked only slightly by most mineral acids.
contact2. Tungsten nickel iron (WNiFe) has comparatively higher strength and ductility than tungsten nickel copper (WNiCu). However, W-Ni-Fe alloy belongs to magnetic alloy and might slightly interrupt or divert the surrounding magnetic field. Therefore, it is not always the preferable tungsten alloy material in applications such as aerospace and ...
