Wolfram Sheet

Wolfram sheets are flat rolled products made from wolfram multi-grade rods.

Specifications

The sheet from wolfram possesses unique constructional characteristics. It is one of the most refractory metals in the world, with a low coefficient of thermal expansion. High anti-corrosion properties, chemical inertness in the gaseous medium, hardness and elasticity emit wolfram from the general list of rare metals.

To produce a sheet, the raw material is pressed, then heated and forged, the final raw material is subjected to shell rolling.

To connect several sheets together they usually use rivets, not welding.

All these products are characterized by high gamma-ray absorption. They have electrical resistance at 5.5 * 10-8 Ohm * m and a small coefficient of thermal expansion. Can be operated at high temperatures (up to 2500 ° C)

The sheets are made of tungsten powder PV1, PV2

Sheets are made from 0.5 to 45 mm thick, with cut edges or machined according to customer requirements. Width – up to 200 mm, length – up to 500 mm

Sheets of various tungsten alloys are also available: W-Al, WC20, WCe20, WCu-10-WCu50,

WL10, 15, 20 , WLa10, 15, 20, W-Ni-Cu, W-Ni-Fe, W–Re, WT20

Application

Wolfram sheet is widely used in electronics, chemical experiments, metallurgy,  energy. Thinner sheets are used in devices of electric lamps and electric furnaces. The use of wolfram sheet in the manufacture of heat-resistant screens and forms is widespread.
