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 […]

TANTALUM Atomic symbol: Ta Atomic weight: 80.9479 Atomic number: 73 Electron configuration: 2-8-18-32-11-2 Oxidation states: +5 State of matter: solid          Heavy metal, ductile Discovered in 1802 by Anders Gustaf Ekeberg Boils at 5425°C, melts at 2996°C Notes: Tantalum is a silver-gray, very hard, malleable, ductile metal. Its properties are similar to that of the […]

PRASEODYMIUM Atomic symbol: Pr Atomic weight: 140.90765 Atomic number: 59 Electron configuration: 2-8-18-21-8-2 Oxidation states: +3 State of matter: solid Heavy metal, brittle Discovered in 1885 by Carl Auer von Welsbach Boils at 3212°C, melts at 931°C Notes: Praseodymium is a silver, moderately soft, ductile, and malleable metal. Small amounts of praseodymium are used in […]
