Tungsten-rhenium Alloy Gold-plated Heat Sink Metal Injection Molding MIM Parts

Rhenium is a chemical element with the symbol Re and atomic number 75. Rhenium is a silvery-white heavy metal and belongs to the 6th period transition metal in the periodic table. It is one of the rarest elements in the earth's crust, with an average content estimated at one billionth, and is also one of the elements with the highest melting and boiling points.

Rhenium is expensive, and rhenium-containing alloys are mostly used in applications, among which tungsten-rhenium and molybdenum-rhenium alloys are the most widely used. Tungsten-rhenium alloys contain 10% to 26% rhenium, and molybdenum-rhenium alloys contain 11% to 50% rhenium. In addition, there are W-33.3Mo-33.3Re, Mo-Re-Hf-Zr, and Mo-Re-Hf-V alloys, the latter two alloys have higher strength. Tungsten-rhenium and molybdenum-rhenium alloys have good high-temperature strength and plasticity, and can be processed into plates, sheets, wires, filaments, and rods for high-temperature structural parts, elastic components, electronic components, etc. in aerospace. They can also be used to manufacture heating elements, workpieces, light bulbs, X-ray equipment, and medical equipment. W-Re-ThO2 alloy can be used as a high-temperature heating workpiece. Tungsten-rhenium and molybdenum-rhenium alloy contacts have high resistance to thermal corrosion and high-temperature electrical conductivity, which can improve the service life and working reliability of power supply equipment.

Qinhuangdao Zhongwei Precision Machinery Co., Ltd. was established in 1997.
