(Summary description)More specifically, an appropriate amount of rhenium can be dissolved in tungsten to form a solid solution alloy powder.

Information

As a representative of refractory metals, tungsten (W) and rhenium (Re) can be combined into tungsten-rhenium alloy powder. More specifically, an appropriate amount of rhenium can be dissolved in tungsten to form a solid solution alloy powder. According to the different appearance and shape, W-Re powder can be divided into spherical tungsten-rhenium alloy powder and irregular tungsten-rhenium alloy powder.

Wholesale Spherical tungsten powder

The steps of preparing spherical W-Re alloy powder include: 1) ingredients: take a certain amount of ammonium paratungstate and ammonium rhenate; 2) mixing: prepare ammonium paratungstate and ammonium rhenate into a solution, and dry and crystallize; 3) reduction: in In a hydrogen atmosphere, the mixed crystals are reduced to tungsten-rhenium alloy powder; 4) Forming: the W-Re alloy powder is put into a mold, and cold isostatic pressing is formed; 5) Sintering: the product of step 4) is sintered in a hydrogen atmosphere Heating, heat preservation and sintering to obtain tungsten-rhenium alloy billet; 6) Processing: the billet needs to be processed by rotary forging, straightening and peeling; 7) Spherical tungsten-rhenium alloy powder can be obtained by plasma rotary atomization.
