High-density tungsten alloy, also known as tungsten-based heavy alloy, is a type of alloy made of tungsten as the matrix element (85% ~ 99% mass fraction) with the addition of Ni, Cu, Fe and other alloy elements by liquid phase sintering. The density is up to 16.5 ~ 19.0g / cc. The most commonly used are […]

Rare earth metals have typical metal properties. They have strong chemical activity and can form a variety of compounds, including hydrides, chlorides, silicides, carbides, organic / inorganic salts and complexes. This is the basis for the rare earth metal in the metallurgical industry as a purification, impurity removal and refinement modifier. Rare earth metals are unstable […]

The finished products of niobium and niobium alloy materials and their processing and preparation processes need to be annealed and heat treated. The heat treatment methods include homogenization heat treatment, stress relief heat treatment, recrystallization heat treatment and mechanical heat treatment. -Homogenization heat treatment. The homogenization heat treatment is to eliminate defects such as metastable phases and […]

Molybdenum-rare earth oxide alloy (Mo-REO), also called rare earth molybdenum, is an alloy of molybdenum and rare earth element oxides, which is an oxide dispersion-strengthened alloy, similar to rare earth tungsten. Commonly used rare earth element oxides are Y2O3, La2O3, CeO2, and Nd2O3, Sm2O3, Gd2O3, and Sc2O3. They are usually added in the alloy in an […]

There are several types of tantalum pipe, such as extruded pipe, rolled pipe, drawn pipe, spinning pipe and welded pipe. The production methods of tantalum tube blanks mainly include extrusion, sheet spinning and strip welding. The finished tantalum tube production methods mainly include rolling, stretching and spinning. Rolled pipe Tantalum tubes are usually cold rolled, including two-roller & […]

Silicon is a chemical element with the symbol Si and atomic number 14. It is from the same group with carbon, germanium and tin. They all have similar properties, and are all tetravalent metalloid and semiconductor. Silicon powder is made from silicon lump by breaking & milling. Depending on the purity & particle size of […]

Scandium (Sc, atomic number 21) is a rare earth element with atomic weight 44.955908. Its melting point is 2,806°F (1,541°C). The appearance of its metal form is silvery-white while slightly yellowish or pinkish cast when oxidized in air. It can be dissolved slowly in most dilute acids. Similar to the early founded lanthan and yttrium, in the fullerene […]

Processing performance Tantalum has good plasticity, low deformation resistance, and low process hardening. It can be processed into plates, strips, foils, pipes, rods and wires at room temperature. Tantalum can be formed into various devices & parts using traditional processes, equipment and tools such as metal spinning, deep drawing, bulging, bending, punching & cutting, stamping […]

Molybdenum is a refractory metal with the symbol Mo and atomic number 42. It is most commonly used as a high temperature, corrosion resistant metal alloy in steel, cast iron and super alloys for the military and defense industry, semiconductor industry and specialty machine shops. Molybdenum metal products are available in plate, sheet, strip & foil, bar, […]

The most common definition of refractory metals includes five elements: niobium, molybdenum, tantalum, tungsten, and rhenium. They share some properties, including a melting point above 2000 °C and high hardness at room temperature. Their machineabilities are quite different, we will introduce the processed & applications for these metal in solid bar form here. Most common processing […]
