Use
Capacitor-grade niobium wire and niobium alloy wire are mainly used as anode leads of niobium electrolytic capacitors
Mechanical properties:
The mechanical properties of common capacitor-grade niobium wire and niobium alloy wire (annealed) are as follows:
Niobium wire grade Nb, tensile strength is ≥245MPa, elongation is 15.0%
Niobium zirconium wire grade is Nb1Zr tensile strength is ≤650MPa, elongation is ≥10%
Electrical performance:
The electrical performance requirements of a foreign company for niobium zirconium wire are as follows:
Niobium zirconium wire supplied in a soft state, tensile strength ≤650MPa, elongation ≥10%, leakage current ≤10UA, capacitance 0.04-0.08UF, dielectric loss tangent value at 120Hz ≤3%. The characteristics after annealing at 1450° are: tensile strength≤650MPa, elongation>5%, grain size≤125um
Process performance:
Common capacitor-grade niobium wire and niobium alloy wire are bent more than 25 times before sintering, and more than 15 times after sintering at 1450° for 30 minutes. The surface quality is smooth, shiny, and free of burrs, grease, scars, and other defects.
Selection suggestion:
Since niobium electrolytic capacitors are still in the research and development stage, the capacitor-grade niobium and niobium alloy wires that are matched with them are also in the sample development stage. There are many qualities and specifications, and the requirements of capacitor manufacturers are different. The manufacturing process and production level of niobium capacitors, as well as the chemical purity of capacitor-grade niobium powder used with them, should appropriately select the varieties and specifications of capacitor-grade you or niobium-zirconium wire.
