The quality parameters of tungsten powder are powder size and purity. Although the essence of the growth of tungsten particles is the volatile deposition during the reduction process, there are many influencing factors, including raw materials, hydrogen flow rate and technological conditions. Raw material In the preparation of ultrafine tungsten powder, the selection of powder […]
People in wire cutting industry know that molybdenum wire breakage is often occurring in the wire cutting process. So why do molybdenum wires always break in the wire cutting? Molybdenum wire of wire cutting In normal conditions, the diameter loss of molybdenum wire per cutting l0000mm2 is approximately 0.001~0.02mm. Therefore, molybdenum wire should be replaced in time […]
Tungsten is the most widely used refractory metal. It’s melting point is 3410℃, so it still has good conductivity and thermal conductivity under the conditions of low thermal expansion, low vapor pressure, and high temperature. As a form of wire, its high-temperature performance is crucial for the production of lighting products and other products. In […]
Rhenium is a rare refractory metal that not only has good plastic, mechanical and creeps properties, but also has good wear and corrosion resistance. Rhenium can be processed into rhenium plates, rhenium rods, sheets, as well as wires, and are widely used in aerospace, electronic industry, petrochemical industry, and other fields. According to data released […]
When it comes to the world’s highest melting point or the most refractory material, many people jump the gun and say “Tungsten.” But I want to tell you that this answer is only half true. As we all know, tungsten is a pure metal with the highest melting point in the world, but the most […]
