Product Description:

Tungsten heavy alloy (WNiFe and WNiCu) contains 80%-98% tungsten along with small amounts of nickel, iron and copper elements. After going through the compacting and sintering process, tungsten is alloyed with other metals, all beginning as a form of powder.

W-Ni-Fe alloy has comparatively higher strength and ductility than W-Ni-Cu alloy. However, W-Ni-Fe alloy belongs to magnetic alloy and might slightly interrupt or divert the surrounding magnetic field. Therefore, it isn’t always the preferable tungsten alloy material in applications such as aerospace and electronic devices. W-Ni–Cu alloy is non-magnetic and has a better electronic and thermal conductivity so it is more suitable for components that are required to work under a magnetic environment, such as the contact of high voltage devices and electrodes.

Tungsten heavy alloy is excellent in applications requiring high performance in corrosion resistance, density, machinability and radiation shielding.

Application:

This kind of alloy is non-ferromagnetic and has relatively good conductivity and thermal conductivity. It is often used in some special occasions, such as gyroscope rotor and other devices and instruments required to work under the action of magnetic field.High voltage electric switch contacts and some electrodes for electrical processing.
