Molybdenum Tungsten MoW Alloy Bar

Molybdenum Tungsten MoW Alloy bar has an excellent performance in preventing corrosion of molten zinc and can be used at higher temperatures than molybdenum or molybdenum alloys. Molybdenum has a high melting point and high density, so tungsten molybdenum alloy also has these characteristics. Molybdenum and tungsten alloy can have a different proportion of tungsten, such as 30% tungsten or 50% of tungsten, 70% tungsten, or 90% tungsten.

The melting point of tungsten molybdenum alloy increases with the increase of tungsten content. When the tungsten content increases to 25%, the melting point of the alloy is about 200 ℃ higher than that of pure molybdenum. Therefore, the corresponding alloy composition can be selected within the range of 2620~3410 ℃ according to the usage temperature and required alloy melting point.

Molybdenum Tungsten MoW Alloy bar type, including disc, granules, ingot, pellets, pieces, powder, rod, wire, sputtering target, and in numerous other forms and custom shapes. Other shapes are available by request.

Raw material selection: The preparation of molybdenum-tungsten alloy rods usually uses high-purity molybdenum powder and tungsten powder as raw materials. Ensuring the high purity of raw materials is the basis for producing high-quality alloy rods.
Processing technology:
Powder metallurgy: After mixing molybdenum powder and tungsten powder in proportion, they are prepared into alloy rods through pressing, sintering, and other processes. This method can accurately control the composition ratio and ensure the uniformity of the alloy.
Vacuum melting method: Melting in a vacuum environment reduces the mixing of impurities and improves the purity and performance of the alloy.
Hot isostatic pressing (HIP): Through high temperature and high pressure treatment, the density and mechanical properties of the alloy are further improved.

Excellent High-Temperature Performance:
Molybdenum has a high melting point, low vapor pressure, and good strength at high temperatures. Adding tungsten further improves the alloy's heat resistance, allowing it to stay stable at even higher temperatures. For example, Mo-30W alloy has a high recrystallization temperature and better creep resistance in extreme heat.

Strong Corrosion Resistance:
The alloy resists corrosion well, especially against molten zinc and other liquid metals. This makes it ideal for zinc smelting and other high-temperature, corrosive environments. It also performs well against corrosion in glass manufacturing.

Well-Balanced Properties:
It combines the advantages of molybdenum and tungsten. It keeps molybdenum's high thermal conductivity and low thermal expansion, while also offering tungsten's strength and density. This makes it a highly versatile material.

Zinc Smelting Industry:
MoW alloy bars are widely used to make zinc temperature measurement tubes, pump rotors, and stirring tools in zinc smelting furnaces. This is because they resist corrosion from molten zinc very well.

Glass Manufacturing:
In glass production, this alloy is used to make stirring tools. It can withstand the high temperatures and corrosive effects of molten glass.

Aerospace Industry:
Thanks to its high melting point and resistance to heat and erosion, MoW alloy is used in parts like solid rocket engine vanes and protective shields. It performs well against high-speed particle flames.

Electronics Industry:
MoW alloy is also used to make sputtering targets for flat-panel displays. It shows good etching behavior in thin-film transistor production.

Composition control: strictly control the ratio of molybdenum and tungsten to ensure the composition accuracy of the alloy. For example, the ratio of molybdenum and tungsten in MoW50 alloy is 50:50.
Impurity control: strictly control the content of impurities such as oxygen and carbon to ensure the purity and performance of the alloy.
Performance testing: mechanical, thermal, and electrical properties of the finished product are tested to ensure that it meets the standards.
