Introduction
Molybdenum-tungsten alloys, also known as molybdena-tungstén alloys are a combination of molybdenum (Mo) and tungsten (W) metals. They have been used for a variety of engineering applications due to their unique properties, including high strength, good thermal and electrical conductivity, good wear resistance and low cost. In addition, these alloys have excellent corrosion resistance and can be used in a variety of severe environments.
Physical Properties
Molybdenum-tungsten alloys are composed of two metals with very different physical properties. Molybdenum has a melting point of 2890C (5192F) and is relatively soft compared to tungsten. On the other hand, tungsten has an exceptionally high melting point of 3410C (6180F) and is much harder than molybdenum. This combination of physical properties gives molybdenum-tungsten alloys a unique set of properties that are suitable for use in many engineering applications.
Molybdenum-tungsten alloys can be produced in a variety of different grades and composites. Common grades of molybdenum-tungsten alloys include the following: Mo-10W, which contains two-thirds molybdenum and one-third tungsten; Mo-15W, which contains one-half molybdenum and one-half tungsten; Mo-20W, which contains one-third molybdenum and two-thirds tungsten; and Mo-25W, which contains one-quarter molybdenum and three-quarters tungsten. Other grades are available depending on the intended application.
Applications
Molybdenum-tungsten alloys are used in a variety of industries, including aerospace, automotive, electrical, and medical. The unique properties of these alloys make them ideal for a range of applications, including high-temperature components and structures, aerospace fasteners, ballistic protection, and electrical connectors. The excellent corrosion resistance of these alloys makes them suitable for use in many environments, and the good thermal and electrical conductivity makes them ideal for use in a variety of electrical applications.
Conclusion
Molybdenum-tungsten alloys are a popular choice for many engineering applications due to their unique properties and low cost. These alloys are composed of two distinct metals, molybdenum and tungsten, and can be produced in a variety of different grades. They offer excellent strength, good thermal and electrical conductivity, good wear resistance and excellent corrosion resistance. In addition, these alloys are suitable for use in a variety of severe environments due to their excellent properties.
