Molybdenum Tungsten Alloy

Molybdenum Tungsten Alloy is composed of molybdenum and tungsten and is obtained through powder metallurgy. HM provides high-precision molybdenum tungsten alloy products in various forms, including rods, plates, sheets, bars, tubes, blocks, pellets, wires, and discs, all crafted to ensure exceptional quality and customer satisfaction. We manufacture large, complex parts using isostatic pressure molding technology, while smaller parts are produced through extrusion, molding, and injection molding techniques. Additionally, rods and sheets are fabricated using forging and rolling processes.

Molybdenum Tungsten Alloy Applications

Zinc Smelting: Molybdenum-tungsten alloy has good resistance to zinc leaching, and is commonly used in zinc temperature measuring tubes, zinc pump rotors, and other parts used in the zinc processing industry.
Glass Manufacturing: molybdenum-tungsten alloy can be used to manufacture stirrers.
Electronics and Optics: Molybdenum-tungsten alloys are used as electrodes or structural parts in electron tubes and thyristors.
High-temperature Components: Molybdenum-tungsten alloys are also commonly used to manufacture electrodes for high-temperature furnaces, flow ports, and thimble components.

Molybdenum Tungsten Alloy Packaging

The Molybdenum Tungsten Alloy is carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
