Typically made of 99.9% pure tantalum, Tantalum Shims from Marsh Nickel Alloys contain trace elements like oxygen, nitrogen, and hydrogen. This high-purity metal showcases excellent ductility and outstanding corrosion resistance, particularly in acidic environments. Tantalum boasts a high melting point of around 3,017°C and a density of 16.6 g/cm³. Its tensile strength falls between 200–250 MPa (in an annealed state), with elongation reaching up to 30%. These impressive mechanical properties, along with a low coefficient of thermal expansion, make Tantalum Shims perfect for delivering precise and stable performance even under high-stress conditions.
