The physical properties of tungsten-molybdenum alloy include the following aspects:
High melting point
The melting point of tungsten-molybdenum alloy is very high, generally about 3410 degrees Celsius, which makes it have excellent stability and heat resistance in high temperature environment. The specific melting point will also vary according to the ratio of tungsten and molybdenum in the alloy. For example, the melting point of tungsten-molybdenum alloy composed of 96.5% tungsten and 3.5% molybdenum is about 3300°C; and when the ratio of tungsten and molybdenum is 90% and 10% respectively, the melting point is about 3000°C.
High density
The density of tungsten-molybdenum alloy is usually between 16 and 18 grams per cubic centimeter, which has a high density, making it a lightweight and small material.
High strength and hardness
Tungsten-molybdenum alloy has high strength and hardness, can resist external impact and deformation, and has good wear resistance and corrosion resistance. Its hardness characteristics mainly depend on the tungsten content in the alloy. The higher the tungsten content, the higher the hardness. In addition, the hardness and strength of tungsten-molybdenum alloy basically increase with the increase of tungsten content.
Good thermal conductivity and electrical conductivity
Tungsten-molybdenum alloy has good thermal conductivity and electrical conductivity, and can quickly conduct heat and current, which makes it have good heat dissipation effect in high temperature environment and suitable for thermal management and electronic devices in spacecraft.
Excellent electronic properties
Tungsten-molybdenum alloy has good electronic properties, low resistivity and high electrical conductivity, and is suitable for high-frequency electronic devices and electronic packaging materials.
Good machinability
Tungsten-molybdenum alloy has good plasticity and machinability, and can be formed and processed by methods such as hot working and cold working.
In summary, tungsten-molybdenum alloy has excellent performance in high temperature, high strength, high corrosion resistance, etc. due to its unique physical properties, and is widely used in aerospace, electronics industry, chemical industry and other fields. For more information, it is recommended to consult relevant research literature in the field of materials science or consult experts in this field.
