Tantalum has excellent corrosion resistance and can withstand strong corrosive media such as acid and alkali. It performs well in corrosive environments such as chemical and electroplating. The melting point of tantalum is as high as 2996 ℃, and tantalum wire can be used for heating elements in high-temperature environments, such as high-temperature furnaces. It has good biocompatibility, no irritation or toxicity to human tissues, and can be used in the medical field. Tantalum wire has high tensile strength and ductility, and can be used to make various shapes of wires and springs.
Tantalum wire comes in various diameter specifications, with coil wire diameter generally ranging from 0.6 to 5mm, straight wire diameter ranging from 1 to 3mm, and a maximum length of 2m. It can be divided into metallurgical tantalum wire with a purity of 99.0% Ta, high-purity tantalum wire with a purity of 99.0% -99.9% Ta, and ultra-high purity tantalum wire with a purity of 99.9% -99.99% Ta. It can also be divided into chemical corrosion-resistant tantalum wire, high temperature resistant high-strength tantalum wire, oxygen resistant brittle tantalum wire, and capacitor tantalum wire.
Tantalum wire for capacitors can be divided into tantalum wire for solid tantalum electrolytic capacitors, tantalum wire for liquid tantalum electrolytic capacitor leads, and tantalum wire for capacitors with reliability indicators. It can be divided into soft state (M), with a tensile strength of 300-600MPa; Semi hard state (Y2), with a tensile strength of 600-1000MPa; Hard state (Y), tensile strength greater than 1000MPa. Mainly using powder metallurgy and melting methods.
Tantalum wire is the most commonly used in the electronics industry, mainly for the anode lead of tantalum electrolytic capacitors, with about 65% of tantalum wire used in this field. Due to its biocompatibility, tantalum wire can be used to compensate for muscle tissue, suture nerves and tendons, and can also be used to make medical devices such as artificial joints. Tantalum wire can be used to make heating components for vacuum high-temperature furnaces, which can work stably in high-temperature environments. Tantalum wire has good toughness and corrosion resistance, and can be used to make high-end eyeglass frames.
