Tantalum is a very rare, pure earth metal that is extremely inert in comparison to other contemporary metals. This elusive, hypoallergenic metal is also very ductile, allowing it to be stretched unlike other forms of contemporary metals in the market. Tantalum is not an alloy.
*ALL Tantalum by Benchmark is guaranteed to be a conflict-free metal.
