What is the unique properties of tungsten rhenium alloy？

Tungsten-rhenium alloy has a series of excellent properties such as high melting point, high strength, high hardness, high plasticity, high recrystallization temperature, high electrical resistivity, low vapor pressure, low electron work function and low plastic brittle transition temperature.When the temperature reaches 1500℃,the tensile property of tungsten-rhenium alloy is much higher than those of pure tungsten.
