Revolutionize Your Next Project with Tantalum Sheet Technology.
Tantalum is a member of the refractory metals group and is almost immune to chemical attacks. It has a high melting point and is resistant to hydrofluoric acid, acids that contain the fluoride ion, and free sulphur trioxide.
Easily fabricated by heat and pressure, it can be formed into a wide range of shapes. Its flexible nature makes it ideal for bending, stamping, and pressing.
It has a shallow carbon content (about 3%) and is not toxic or flammable. It is also one of the few refractory metals that can be melted into thin sheets.
Aluminium, copper, and other conductive materials are often coated with tantalum nitride in order to create a barrier layer that protects the metal from moisture. It is also used in electrical engineering to make thin film resistors and integrated circuit processes.
Welding & Cutting
Various tools are available for welding tantalum, including acetylene torch welders and resistance welding equipment. Unlike other metals, tantalum has a relatively high melting point and therefore requires a higher power input to achieve a good weld.
During the welding process, the electrode should be constantly kept cool to minimize the heating of the metal. Using an arc-free class 2 electrode with internal water cooling will ensure the best results.
The cutting of annealed and sintered tantalum can be done with the same techniques as soft copper, but it is recommended that a minimum of 100 surface ft./minute be used for most turning operations. Cemented carbide tools with positive rake and angle are best.
