Titanium Wire / Silk
We could provide tantalum wire of vacuum electron beam melting and powder metallurgy technology, General purpose of tantalum wire was produced by vacuum electron beam melting technology，it has a relatively high purity. Capacitor grade tantalum wire usually was produced by powder metallurgy technology, it contains more special metal elements. Tantalum wire was produced on the basis of tantalum bar. first of all, rolling out the appropriate size of tantalum bar, cleaning the tantalum bar, to remove surface magazine and oil pollution, trimming the tantalum bar and clean again, then through stretching and annealing for many times, eventually get the specifications of customer requirements, through cleaning, straightening, winding, we can get the straight wire or coil. Giant Metal unique method of rolling, stretching process, compression ratio control, annealing temperature and annealing time control could guarantee tantalum wire have excellent mechanical properties, make the surface smooth, clean, no oil, there is no cracks and burrs, no mess around, and observed under 25 times magnification, it have not continuous dents and scratches, have good metallurgical structure, so as to ensure the quality of tantalum wire are better than other companies in the same industry.
In addition to provide pure tantalum wire, our company also provide tantalum alloy wire.

Application
Capacitor grade tantalum wire is mainly used for making tantalum electrolytic capacitor anode lead. tantalum wire is the key material to tantalum capacitor, tantalum capacitor is the best capacitor, about 65% of the world’s tantalum used in this field.
Be used to produce tantalum mesh.
Be used to suture to compensate muscle tissue, stitch nerves and tendons, production blood vessels stent, etc.
Be used to produce vacuum high temperature furnace heating components.
Used for vacuum electron emitting cathode source, ion sputtering and coating materials, etc.
