5. Hardware

We also could produce other Ta/Nb hardware as per customer’s special requirement.
1) Tantalum&Niobium heating hardware is mainly used for heating element in high temperature vacuum furnaces.
2) Tantalum&Niobium shielding screens is mainly used for shielding screens in high temperature vacuum furnaces.
3) Tantalum&Niobium crucibles are mainly used for rare-earth metallurgy, load plates for anodes of tantalum and niobium electrolyzing capacitors and corrosion resistant containers in chemical industries.
