Product Description

Kefeng's tungsten alloy's unique physical features of higher density than lead, the material tungsten alloy can be processed as a lead replacement for shielding against X-rays and gamma radiation.  It allows a reduction in the physical size of shielding components, without compromising their rigidity or the effectiveness of the shielding characteristics and protect sensitive electronic equipment or delicate human tissue, the energy-absorbing properties of Kefeng tungsten alloys make them exceptional choices for radiation shielding applications, in both medical and industrial settings.
Compared to traditional radiation shielding materials, tungsten alloys provide excellent value. A high-density alloy can provide the same energy absorption as lead using 1/3 less material! Unlike lead, you'll also reduce administration costs by eliminating the need to obtain special licensing-it's not required.  Our products are available as finished machining parts or as short rod, round bar, rectangular blocks and other shapes per your requirements and drawings.
 

Tungsten high temperature resistance and melting point make it the most common choice for use in applications like high-temperature furnaces, whose heating elements, heat shields and boats must resist working temperatures up to 1300 °C.

In addition, in metallurgical industry, some components of electric-resistance furnaces are made of tungsten flat products (tungsten sheets and foils). These furnaces are used to sinter refractory metals into billets and semi-finished products. The refractory metals include tungsten, molybdenum, tantalum and niobium.

Tungsten heating elements are the core of high-temperature furnaces, where working temperatures can rise to 2800°C and remain in the 2300-2350°C range for long periods of time. Such heating elements are usually in shape ofcylindrical shells or pieces of closed-end tungsten sheets riveted by tungsten bolts. Tungsten heat shields are the insulating components of high temperature furnaces, and riveted tungsten sheet is popular for use as the internal layers of these shields.

Tungsten High temperature Evaporation Source
Tungsten plates and sheets are a popular material for use as evaporation boats due to their very high melting point, low vapor pressure, and stable chemical properties under high temperature. During the evaporating process, tungsten ensures that no impure particles enter the vapor and penetrate the layer adhering to the base.
