Tantalum wire can be processed according to standard ASTM F560 and ASTM B365. Tantalum is a sensible choice whenever high corrosion resistance is required. Even though tantalum is not one of the noble metals, it is comparable to them in terms of chemical resistance.
Tantalum wire, Tantalum filament
Tantalum wire is made by tantalum powder as raw material after rolling and drawing. Tantalum wire is used in the largest amount of electronics industry, mainly for the anode lead of tantalum electrolytic capacitors.
Tantalum wire Tantalum- tungsten alloy wire
Material:RO5200 RO5400 RO5252(Ta-2.5W) RO5255(Ta-10W)
Available size:>=0.25mm in coil or in straight
Standard: As per ASTM B365-98
Capacitor grade tantalum anode lead wire is mainly used to produce a tantalum electrolytic capacitor. Beijing Oriental color in the current production of tantalum and niobium capacitor grade tantalum wire in different states, different specifications can be divided into more than 30 varieties. The smallest diameter tantalum wire was 0.10mm. Yarn may also be made of tantalum or tantalum mesh, the key material is tantalum wire tantalum capacitors, tantalum capacitors are the best, about 65% of the world tantalum is applied to the field.
To compensate for muscle tissue, and can be used to suture the nerves and tendons. Beijing Oriental color of tantalum and niobium may provide different states, different specifications of the tantalum wire. The smallest diameter tantalum wire was 0.1mm. Tantalum wire can produce high-temperature vacuum furnace heating member.
Tantalum wire in the largest amount of electronics industry, mainly for the anode lead of tantalum electrolytic capacitors.
High oxygen embrittlement of the tantalum wire may also be used to produce a tantalum foil capacitors, it can operate at a high temperature of 772 (100 deg.] C) and ultra-high sparking voltage (350V) and potassium dichromate in sulfuric acid conditions forming solution. Further, the vacuum can also be used tantalum wire cathode electron emission source, ion sputtering and coating materials.
Tantalum is a sensible choice whenever high corrosion resistance is required. Even though tantalum is not one of the noble metals, it is comparable to them in terms of chemical resistance. In addition, tantalum is very easy to work at well below room temperature despite its bodycentered cubic crystal structure.
