• Description

Tungsten Rhenium Sputtering Target

Uses: Tungsten-rhenium alloy has good electrical properties, ductility and processability, and can be used for thermocouple temperature measurement in high temperature furnaces.

Applicable conditions: due to the excellent high temperature strength and high temperature plasticity of W-Re alloy, various structural parts, heaters and special-shaped parts made of W-Re alloy are widely used in aerospace, atomic energy, ultra-high temperature alloy, semiconductor magnetron sputtering, high temperature heat field and other industrial fields.

For X-ray tube, tungsten rhenium molybdenum alloy layer composite anode target material and its preparation method are used. The target material includes tungsten rhenium alloy layer and molybdenum alloy layer. The tungsten rhenium pre alloy powder is prepared by mixing tungsten powder and ammonium rhenate solution and reducing after drying. In the tungsten rhenium pre alloy powder, the mass fraction of rhenium is 1-5%, and the surplus is tungsten. The target material is made of tungsten powder, ammonium rhenate and molybdenum alloy powder by prealloying, molding, medium frequency sintering, high temperature shaping and machining. The high activity tungsten rhenium pre alloy coating powder with special proportion prepared by the invention has more uniform composition and higher activity. The tungsten rhenium molybdenum alloy layer composite anode target with uniform composition and fine and uniform grain structure is prepared by the invention. The qualified rate of the finished product is high, the process is few, and the cost is low.

Although molybdenum target X-ray tube is clear for soft tissue radiography. However, the effect on the breasts of adolescent women and the dense breasts that have not yet been breastfed is poor, especially when the thickness of soft tissue is more than 6cm, it is difficult to take pictures. For this reason, JINXING MATECH uses tungsten rhenium alloy as the target of X-ray tube.
