miningrhenium tantalum m


Tantalum and niobium are biocompatible and non-allergenic, with high melting points, high corrosion resistance, and ductility at high temperatures. They also have a small coefficient of thermal expansion, and excellent thermal and electrical conductivity, for application to medical care, aerospace, chemical reaction processes and many other uses in metal additive manufacturing.

What are conflict minerals?

What are conflict minerals? "Conflict minerals," as defined by the US legislation, currently include the metals tantalum, tin, tungsten and gold, which are the extracts of the minerals cassiterite, columbite-tantalite and wolframite, respectively. Downstream companies often refer to the extracts of these minerals as 3TG.
