As an important metal material, molybdenum products are widely used in many fields. Compared with other metal materials, it has many excellent properties, including:
- High melting point:
Molybdenum has a very high melting point of about 2610℃ to 2623℃, making it suitable for high temperature environments.
- High thermal conductivity:
Molybdenum has high thermal conductivity and can transfer heat quickly. This property allows molybdenum products to maintain stable performance in high temperature environments and are not easily damaged by heat accumulation.
- Good mechanical properties:
Molybdenum products have high strength and hardness, as well as good creep resistance and toughness. These properties can be significantly enhanced by adding other metals to form molybdenum alloys. These mechanical properties allow molybdenum products to maintain stable performance when subjected to large mechanical and thermal stresses. In particular, they can still maintain their structural integrity at high temperatures.
- Low thermal expansion coefficient:
Molybdenum has a low thermal expansion coefficient, which means that the material has good dimensional stability under temperature changes, which is particularly important for the manufacture of precision instruments and equipment.
- Corrosion resistance:
Molybdenum products have good corrosion resistance and show good corrosion resistance in a variety of chemical environments. Especially in oxidizing environments, they perform well. This allows molybdenum products to maintain a long service life in harsh working environments.
Generally, in an atmosphere without oxygen, molybdenum has fairly good corrosion resistance to a variety of acids, metal liquids and molten glass. Within 1100°C, molybdenum is relatively stable in hydrogen, ammonia and nitrogen.
- Good electrical and thermal conductivity:
Molybdenum has good electrical and thermal conductivity, which makes it important in the electronics industry and is often used to manufacture thermal conductive materials and electrode materials in electronic devices. For example, components such as electron tubes and transistors, electrodes and filaments.
However, molybdenum products also have some disadvantages:
- Difficult processing:
Molybdenum has high hardness and brittleness, making its processing relatively complex and difficult. Professional equipment and processes are required during the processing to ensure the quality and performance of the product.
- Easy to oxidize:
Molybdenum is easily oxidized in the air to form a dense oxide film. Although this oxide film can protect the internal molybdenum from further oxidation, the presence of the oxide film will affect the performance and use of the product in some applications that require the molybdenum surface to be exposed.
- High cost:
Molybdenum is a rare metal with high mining and processing costs. Therefore, the price of molybdenum products is relatively high, which limits its application in some fields.
In summary, these properties and characteristics of molybdenum products make it widely used in many fields. However, it is necessary to pay attention to its limitations during use and take corresponding measures to overcome its shortcomings in order to give full play to its advantages.
