Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. The name tungsten comes from the former Swedish name for the tungstate mineral scheelite, tung sten or “heavy stone”, most important properties for tungsten is high melting point and high density. Meanwhile, the hardness is high and it’s quite fragile compare […]
Porous titanium, also named as sintered titanium and titanium foams, is sintered from titanium powder. It has pore structure exhibit high specific strength, high energy absorption, excellent corrosion resistance and biocompatibility. Generally, porous titanium processed from irregular titanium or titanium alloy irregular powder. It can be isostatically pressed, molded, and extruded. The main process for porous […]
Tantalum is the most corrosion resistant metal in common use today. Tantalum is not a noble metal, but it is comparable to them in terms of chemical resistance. When exposed to air, tantalum forms a very dense oxide layer (Ta2O5) which protects the base material from aggression. This oxide layer therefore makes tantalum corrosion-resistant. Tantalum‘s corrosion resistance in […]
With its unique properties, porous titanium can be widely used in the pharmaceutical industry, water treatment industry, food industry, bioengineering, chemical industry, petrochemical, metallurgical industry and gas purification. It is a new material with broad development prospects. Typical uses include: – In the infusion of the pharmaceutical industry, small injections, eye drops, decarbonization filtration in the concentration […]
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 […]
Titanium mesh, can be used as corrosion resistance anode, filtering for corrosive substance. Sacrificial anode is the unique usage for titanium mesh. Titanium expanded mesh is expanded from titanium sheets, the openings are normally diamond. Most common material is grade 2 C.P. Titanium. TERMINOLOGY Titanium mesh opening pic A: S.W.D.: Short Way Diamond B: L.W.D.: Long […]
