Tungsten

Tungsten is a refractory metal with the highest melting point and the lowest expansion coefficient, which is suitable for the use environment with extremely high temperature requirements. It is widely used in manufacturing electronics, electric light source industry, medical treatment, film technology and high temperature furnace components. Gemei has been focusing on the production and research of tungsten materials for many years. With stable production technology and rich experience, it has become a private tungsten and molybdenum production enterprise with large output, good quality and high international cost performance.

Total element analysis report


Since its establishment for more than 20 years, gemei has always applied strict quality control to every process of production, and guided the production site management with quality control to ensure the internal quality, composition and consistency of different batches of products.




In the processing engineering of tungsten and its alloys, in order to obtain more objective test data, we give up self inspection in the chemical composition, mechanical properties, Fisher particle size and other test items of materials, and carry out testing in a third-party organization with testing qualification.

Raw material
Starting from raw materials, it 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.
From powder to finished products, GeMei strictly controls every process in the production process
Blend
Ensure that the materials in the milling and mixing process can be fully stirred and evenly distributed to ensure the consistency of the internal organization of the product.

From powder to finished products, GeMei strictly controls every process in the production process
Extrusion
The pressing process is the process of powder blank forming. The pressing of powder is completed by isostatic pressing equipment to make its internal structure uniform and dense.

From powder to finished products, GeMei strictly controls every process in the production process
After the metal powder is pressed 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 product, which is called sintering.

Forging
Forging technology can make materials obtain higher density, better mechanical properties, and play a role in strengthening the surface.
From powder to finished products, GeMei strictly controls every process in the production process
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.

From powder to finished products, GeMei strictly controls every process in the production process
Heat treatment

It can completely eliminate the internal structural stress of the material, give full play to the best performance of the material, and make the material easier for subsequent machining.

From powder to finished products, GeMei strictly controls every process in the production process
Machining
Through turning, milling, cutting, grinding and other mechanical processing procedures, it can be processed into various customized sizes of customers, and ensure that the internal organization of tungsten and molybdenum materials is tight, stress free and free of holes

From powder to finished products, GeMei strictly controls every process in the production process
Quality testing
Starting from raw materials, quality inspection and control, as well as quality inspection and sampling inspection of each process, continue to ensure the process quality control of each process of the product.
From powder to finished products, GeMei strictly controls every process in the production process
Recycling
or the materials purchased by customers from gemei, the obsolete materials that reach the service life or update the equipment, gemei can help customers recycle and reuse, reducing the use cost of customers.
