Rhenium Bar

Classification: According to the different requirements of use, Rhenium bar according to the physical properties are divided into "high density Rhenium bar" and "medium density Rhenium bar", according to the chemical composition is divided into "high purity 99.99%" and "super pure 99. 999%".

Appearance: Grey or silver metallic square bar or round bar.

Application: Medium density Rhenium bar can be used as additives for super alloys, and high density Rhenium bar can be used for the manufacture of rods, wires or high temperature structural parts.

Specification: 4N Grade Re>99 99%(calculated by subtraction method, except gas element).

5N Grade Re>99.999%(calculated by subtraction method, except gas element).Medium density Rhenium bar ,density is about 12g/cc.High density rhenium bar ,density is about 18 5g/cc.
