MoW & MoRe

[MoW 50/50, 70/30 | MoRe 5, 41]

MoW and MoRe are molybdenum alloys for high-temperature applications. The addition of tungsten (MoW) significantly increases the recrystallization temperature, high-temperature strength and corrosion resistance – preferred fields of application include the zinc industry and stirring tools for glass production. With MoRe, rhenium additives increase the recrystallization temperature and above all the ductility, machinability and weldability; MoRe (similar to WRe) is often used as thermocouple wire. Below you will find the standard grades with compositions and availability; detailed information can be found in the respective data sheets.

Grades & data sheets

Variety	Composition	Available as	data sheet
MoW 50/50	Mo 50% / W 50%	Wires, rods, pins, finished parts according to drawing	On request
MoW 70/30	Mo 70% / W 30%	Wires, rods, pins, finished parts according to drawing	On request
MoRe 5	Mo 95% / Re 5%	Wires, rods, pins, finished parts according to drawing	On request
MoRe 41	Mo 59% / Re 41%	Wires, rods, pins, finished parts according to drawing	On request

The key features are as follows: MoW: high heat resistance/corrosion; MoRe: ductile & weldable; thermocouples

Supply programme
