By alloying molybdenum with rhenium the form stability and furthermore the ductility (reduction in the brittle-ductile transition temperature) can be improved. The PLANSEE standard alloys Mo5Re and Mo41Re include 5 resp. 41 weight% of rhenium.

Advantages compared to pure Mo:

• higher ductility at room temperature
• higher recrystallization temperature
• better weldability
• higher strength

Typical areas of application:

• rocket propulsion components for the aerospace industry
• welded constructions, e.g. heat exchangers for liquid metals and inert gases
• high temperature thermoelements
