tantalum and tantalum alloy sheet, strip and foil is a kind of high temperature resistant, corrosion resistant material. It is similar to glass chemical stability. The strength and stiffness is similar with low carbon steel. high temperature heat intensity after tungsten and tungsten alloy. Tantalum metal is chemical corrosion and high temperature furnace with excellent material. Tantalum strongly from 300 ° start with oxygen, hydrogen, nitrogen and other gases in the air, generate brittle compounds, metal hardness and brittleness decreased, the tantalum plastic - had a greater influence on the brittle transition temperature.
