At Special Metals UK, we are able to provide tantalum bars to a range of specifications to suit your needs. In its pure form, tantalum is a hard, dark-coloured metal, and is famous for its very high melting point and its extreme resistance to corrosion. Able to resist attack by acids like aqua regia, which even corrode gold and platinum, tantalum is also particularly dense and is used across industry, medicine and science.
Tantalum is always found alongside Niobium, and the difficulty of separating the two elements resulted in considerable confusion when they were first discovered. In fact, it was widely believed by the scientific community that the discoverer of Tantalum, Anders Ekeberg, had been wrong about his discovery. Luckily for modern engineering and materials science, he was ultimately proven right.
Tantalum bars are a vital component material across a range of industries, with applications in medicine, industry and high-performance alloy production thanks to its remarkable traits – both chemical and physical. One of these traits is an extreme resistance to corrosion, which makes tantalum perfect for use in highly caustic environments in chemical industry and marine applications, and for use in alloys and coatings.
The other primary attribute of tantalum is its extremely high melting point, which lends tantalum superalloys the temperature resistance needed to fulfil the most intense applications in any field of engineering – nuclear reactor components, jet turbine components, spacecraft and high-pressure chemical manufacturing, among other uses.
In the production of these superalloys, tantalum bar from Special Metals UK is the best blank to begin with – easy to store, easy to measure to the exact level required and made of pure tantalum. The pure metal is also completely bioinert, making it perfect for use in orthopaedic implants and surgical equipment.
