Molybdenum tube

Material Properties

Molybdenum has a melting point of 2610ºC, a boiling point of 5560°C, a density of 10.2g/cm³,and it is insoluble in water and belongs to the fifth period element, with an atomic radius of 139pm and an electronegativity of 2.16. It is a silvery white shiny metal in appearance. It has good electrical and thermal conductivity, low expansion coefficient and high strength at high temperature (1100 ~ 1650 ℃). Compared with tungsten, it is easy to process. Therefore, it has been applied in high-temperature furnaces, electronic tubes, electric light sources, metal processing tool manufacturing departments and aerospace industry. Molybdenum is resistant to corrosion by molten glass, and its oxides do not pollute the glass. Molybdenum has been used in the glass industry as heating electrodes and as sputtering target for solar cell and flat panel display coatings.

Craftsmanship

Raw Material

Starting from raw materials, we select high-quality raw materials, which is very prominent in the stability and consistency of products. Identify different brands of raw materials and mark the batch number. And each batch of raw materials shall be sampled, inspected and archived. Ensure the traceability of each finished product and continuously improve the product quality.

Milling

The control of the milling process of Mengchang Metal products is very accurate, with several large mixers and vibration platforms to ensure that the materials in the pulverizing and mixing process can be fully stirred and evenly distributed, so as to ensure the internal organization consistency of the products.

Suppress

In the process of powder compacting, the powder is pressed by isostatic pressing equipment to make its internal structure uniform and dense. Mengchang has very perfect batch mold, and also has isostatic pressing equipment to meet the production of ultra-large batches of products.

Sinter

In powder metallurgy, after the metal powder is formed by isostatic pressing, it is heated at a temperature lower than the melting point of the main components to make the particles connect, so as to improve the performance of the products, which is called sintering. After the powder is formed, the dense body obtained by sintering is a kind of polycrystalline material. The sintering process directly affects the grain size, pore size and grain boundary shape and distribution in the microstructure, which is the core process of powder metallurgy.

Forging

The forging process can make the material obtain higher density, better mechanical properties, and play a role in strengthening the surface. Accurate control of the processing rate and forging temperature of tungsten and molybdenum materials is an important factor for the superior performance of Mengchang tungsten and molybdenum materials. A processing method of using a forging machine to apply pressure to a metal blank to plastically deform it to obtain a forging with certain mechanical properties, certain shape and size.

Rolling

The rolling process makes the metal material produce continuous plastic deformation under the pressure of the rotating roll, and obtain the required section shape and properties. With advanced tungsten and molybdenum cold and hot rolling technology and equipment, from tungsten and molybdenum metal blank to the production of tungsten and molybdenum foil, mengchang guarantees you more advanced production technology and superior metal properties.

Heat-Treat

After the forging and rolling process, the material is subjected to the heat treatment process to completely eliminate the internal structural stress of the material, give play to the material performance, and make the material easier for subsequent machining. Mengchang has dozens of vacuum furnaces and heat treatment hydrogen furnaces to meet the rapid delivery of mass production orders.

Machining

The material of Mengchanghas undergone complete heat treatment, and then processed into various customized sizes by machining equipment such as turning, milling, cutting, grinding, etc., and ensures that the internal organization of tungsten and molybdenum materials is tight, stress-free and hole-free, which can meet the needs of customers.

Quality Assurance

Quality inspection and control will be carried out from raw materialsand for each steps of the production , so as to continuously ensure the quality every product. At the same time, when finished products are delivered from the warehouse, the appearance, size and internal organization of materials are tested one by one. Therefore, the stability and consistency of products are especially prominent.
