Tantalum wire 0.4mmL

Definition Editor tantalum powder as raw material by rolling, drawing and other filamentous tantalum material made of plastic processing methods. 2 Edit powder metallurgy method for manufacturing process: raw material (tantalum powder) → mixing → forming → → swaging a sintered → intermediate annealing → drawing → annealing → quality inspection → finished product packaging and storage. Melting process: raw material (tantalum powder) → mixing → molding → sintering → electron beam melting pre-→ forging → intermediate annealing → swaging → intermediate annealing → drawing → annealing → quality inspection → finished product packaging and storage. 3 classification can edit their chemical purity j performance, usage and status classification. According to the chemical purity divided into three categories: (1) metallurgy tantalum wire, purity 99.0% Ta; (2) high purity tantalum wire, the purity of 99.0% ~ 99.9% Ta; (3) ultra high purity tantalum wire, purity of 99.9% to 99.99 % Ta. Press performance is divided into four categories: (1) chemical corrosion tantalum wire; (2) high temperature high strength tantalum wire; (3) oxygen embrittlement of tantalum wire; (4) Capacitor tantalum wire. By use of a capacitor tantalum wire is divided into three categories: (1) solid tantalum capacitors lead tantalum wire (TalS, Ta2s) (see Chinese National Standard GB / T3463-1995); (2) liquid tantalum electrolytic capacitors lead tantalum wire ( TalL, Ta2L) (see Chinese National Standard GB / T3463-1995); (3) there are reliability capacitors tantalum wire (DTals, DTalL) (see China's national military standard GJB2511-95). According to state capacitors tantalum wire is divided into three categories: (1) soft state (M), tensile strength σb = 300 ~ 600MPa; (2) semi-hard (Y2), tensile strength σb = 600 ~ 1000MPa; (3) Hard (Y), tensile strength σb> 1000MPa.
