What are the categories of molybdenum bars?
Molybdenum bars are a metal material used to be processed into various shapes. According to different uses and materials, molybdenum bars can be divided into several different categories.

1. Classification by use: Molybdenum bars are mainly used in the electronics industry, vacuum equipment, electric heating elements for high-temperature furnaces, petroleum and chemical industries, medical devices and other uses. According to different uses, molybdenum bars can be divided into several different categories such as electronic molybdenum bars, industrial molybdenum bars, and medical molybdenum bars.

2. Classification by material: Molybdenum bars are mainly made of pure molybdenum and molybdenum alloys. Pure molybdenum bars are mainly used in high-temperature heating equipment, vacuum equipment and other fields. Their operating temperature can reach more than 1800℃ and have good high temperature resistance. Molybdenum alloy bars are made of alloys of molybdenum and other metal elements, such as molybdenum-niobium alloys, molybdenum-titanium alloys, etc., with better strength and heat resistance, suitable for more demanding working environments.

3. Classification by shape: Molybdenum bars have different shapes, such as molybdenum rods, molybdenum plates, molybdenum wires, etc. These shapes have different advantages for different processing needs and uses, so molybdenum bars can also be classified according to different shapes.

4. Classification by processing technology: According to the processing technology and surface treatment of molybdenum bars, they can be divided into cold-processed molybdenum bars and hot-processed molybdenum bars. Cold-processed molybdenum bars have higher surface finish and are suitable for some occasions with high surface requirements. Hot-processed molybdenum bars have better toughness and strength, and are suitable for some occasions with high mechanical properties requirements.

In general, the classification of molybdenum bars mainly depends on factors such as their use, material, shape and processing technology. Different classification methods are suitable for different fields and application needs, and can be selected and applied according to specific circumstances.
