Tantalum

Tantalum is generally made from sintering the powdered ore to produce a metal with an extremely high melting point of approximately 2990°C. It has an excellent resistance to corrosion against molten metals and liquids, is biocompatible and has very high conductivity.

Applications Include;

Tungsten

Tungsten has the highest melting point of these refractory metals at 3422°C. It is very robust and has an extremely high tensile strength; it has the ability to be drawn into very thin wires. Tungsten’s corrosion resistance is also very good.

Applications Include;

• Lighting Elements,
• X-ray targets,
• Heating Elements,
• Missile Components
• and due to its high density is used as counter weights.

Zirconium

Zirconium is a lustrous, greyish-white, soft, ductile, and malleable, it is highly resistant to corrosion by alkalis, acids, salt water, and other agents. The melting point of zirconium is approx 1855°C.

Applications Include;

Niobium

Niobium has a similar structure to Tantalum and is produced in a similar method. It too has a very high melting point of around 2470°C. It has excellent corrosive resistance and has good cold ductility. It is however half as dense as Tantalum.

Applications Include;

Titanium

Titanium (pronounced /ti'tane'ium/) is a chemical element with the symbol Ti and atomic number 22. It is a light, strong, lustrous, corrosion-resistant (including to sea water and chlorine) transition metal with a silver colour.
