1. What are molybdenum tungsten tubes?

Molybdenum tungsten tubes are hollow components made from a refractory alloy of molybdenum and tungsten. They are intended for specialized applications requiring a combination of high-temperature performance and properties tailored by alloy composition.

2. What Mo-W alloy compositions are available?

Commercial Mo-W alloy grades include approximately 70 wt.% molybdenum / 30 wt.% tungsten and 50 wt.% molybdenum / 50 wt.% tungsten. Availability in tubular form must be confirmed with the manufacturer.

3. What are molybdenum tungsten alloy tubes used for?

Potential applications include specialized molten-metal handling components, zinc-processing equipment, glass-industry assemblies, high-temperature protective components, and custom industrial systems. Suitability depends on the component design, environment, and alloy grade.

4. Can Mo-W tubes be manufactured to custom dimensions?

Custom tubular components may be possible depending on alloy composition, manufacturing method, wall thickness, diameter, and length. Provide a drawing specifying OD, ID, wall thickness, tolerances, and end geometry to determine feasibility.

5. What is the difference between molybdenum tubes and molybdenum tungsten tubes?

Pure molybdenum tubes are primarily molybdenum, while Mo-W alloy tubes contain added tungsten. Tungsten can improve selected high-temperature properties and resistance to molten-zinc attack, but the resulting performance depends on the composition and manufacturing condition.

6. Can REG Metals provide a COA and custom material documentation?

REG Metals can request a COA, SDS, chemical composition report, and dimensional inspection documentation from the selected supplier, subject to availability. For critical applications, specify the required traceability, composition limits, inspection method, and acceptance criteria before purchase.
