Product Description

Xi'an Kefeng Powder Metallurgy Co., has involved in manufacturing the high tech materials like High Density and Strength Tungsten Alloy Refractory Metal products, technologies and development expertise for the high performance demands of the oil and gas drilling industry since in1999.

As one of the chinese leading producers of refractory metals such as tungsten, tungsten alloy WNiFe/WNiCu, Copper Tungsten alloy, we also can supply pure molybdenum, TZM and pure tungsten, W-La.

Kefengs' tungsten alloys has become an essential material for a wide variety of applications including balance weights, radiation protection, vibration absorbers, heat transfer and drilling bars. It has the highest melting point of any metal and its high density is equaled only by gold, platinum, and a few other rare and expensive metals.
 

 

Application

Tungsten alloy radiation shields are made to only allow radiation to go where it is actually needed. Our tungsten radiation shields guarantee that environmental radiation exposure is kept to an absolute minimum during the generation of X-ray radiation.  A particularly dense material with excellent shielding properties is needed to ensure that the surrounding tissue is protected and the radiation guided only to the intended locations where those are widely used in Medical and Industrial Radiation Shielding.

There is no licensing required for tungsten alloy materials. Tungsten alloys are stable at high temperatures. You can use one-third less material than lead for the same energy-absorbing effectiveness and also it is non-toxic.  You can use our high density tungsten alloys for shielding wherever radioactivity has to be controlled and directed.   Xi'an Kefeng Powder Metallurgy Co., Ltd. specializes in producing tungsten radiation shields according to customer's drawing.
