What are the excellent properties of tantalum foil?

Specification and purity thickness range: Conventional 0.01-0.5mm, commonly divided into ultra-thin foil, thin foil, and thick foil; Both roll and sheet packaging can be customized; Purity grade: commonly 99.9% (3N), 99.95% (3N5), 99.99% (4N) and above, with grades such as Ta1; Appearance requirements: The surface should be bright, without cracks, peeling, folding, obvious oxidation or impurities pressed in.
The core characteristic is extremely strong chemical stability: only a few media such as hydrofluoric acid can corrode at room temperature; -High melting point (2996 ℃), low vapor pressure, high temperature resistance, radiation resistance, non-magnetic; -Good ductility and conductivity, capable of bending and stamping into complex shapes; -Excellent biocompatibility, non-toxic and non discriminatory to human tissues. Typical electronic applications: tantalum capacitor electrodes (miniaturization, high capacity), semiconductor sputtering targets, vacuum electron tube components; Medical: implantable electrodes, surgical repair materials, high-end medical instrument electrode pads; Chemical/Aviation: High temperature anti-corrosion sealing gaskets, vacuum coating, thermal protection components for aviation engines; Electric light source: High temperature resistant structural components for halogen lamps and quartz glass lamps. Production and standard production adopt multi pass cold rolling and intermediate vacuum annealing, strictly controlling the quality of pinholes and surfaces; Customizable size and condition according to customer requirements
