Rhenium for Scientific Instrument Filaments

Rhenium also has one of the highest modulus of elasticity among all metals, second to only iridium and osmium. As the temperature increases from room temperature to 725 C, rhenium's modulus only decreases about 20%. This property allows for filaments made with pure rhenium to have excellent mechanical stability and rigidity.
