Applications of W tungsten sheet:For producing electric light source parts,components of electric vacuum;producing W-boats,heat shield and heat bodies in high temperature furnace.
Product Introduction
99% Tungsten sheet refers to thin flat piece of material made from tungsten metal that is at least 99% pure. Tungsten is a dense, hard, and durable metal that has the highest melting point of all metals and is known for its excellent mechanical and thermal properties.
Tungsten(W) Plate are used in various industrial applications such as aerospace, electronics, and medical industries due to their high density, high melting point, and resistance to corrosion and wear. 99% tungsten sheet metal are also used in the production of filaments for incandescent light bulbs, heating elements for high-temperature furnaces, and radiation shields in nuclear reactors.
Tungsten sheets can be manufactured using a variety of processes such as hot rolling, cold rolling, and extrusion. The tungsten sheet thickness tolerance can range from a few micrometers to several millimeters, depending on the specific application.

Application Case
One common application for 99% tungsten plates is in the manufacturing of heating elements for high-temperature furnaces. Tungsten sheets are used as a base material for these heating elements because they can withstand extremely high temperatures without melting or deforming.Tungsten sheetsthickness tolerance depends on customer requirements.
Another application is in the production of X-ray targets. The high density of tungsten makes it an ideal material for X-ray targets because it can absorb and dissipate the heat generated by the X-ray beam.
Tungsten sheet metal are also used in the aerospace industry for their high strength and resistance to corrosion. They are used as shielding material for spacecraft and satellites to protect them from the harsh radiation environment in space.
Other applications for 99% tungsten plates include the production of electrodes for welding and cutting, as well as for the manufacture of electrical contacts and heat sinks.
