What Is Tantalum?

Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant.

It has many uses, such as in the electronics industry for capacitors and high power resistors. It is also used to make alloys to increase strength, ductility and corrosion resistance. The metal is used in dental and surgical instruments and implants, as it causes no immune response.

A fun fact about this metal – it was previously known as Tantalium, and it is named after Tantalus, a villain from Greek mythology.

It’s mainly found in in Australia, Brazil, Mozambique, Thailand, Portugal, Nigeria, Zaire and Canada.

When mentioning that a certain metal causes no immune response, using it for jewelry is a great benefit to those who have concerns. Because it does not react to most chemicals, Tantalum is hypoallergenic. When a piece of jewelry is considered hypoallergenic this means that you can expect to wear and enjoy your jewelry with little to no reactions, even for many who experience reactions to most jewelry. Tantalum, like gold, is highly malleable and can be resized as needed. It can even be cut in an emergency.

The weight of Tantalum is similar to platinum and the color will not fade or change over time. Even though the metal will show wear over time, it can take daily wear without cracking and breaking.
