MHC alloy

From powder to finished products, we independently control the process of each production process. We can ensure better quality of finished products and perfect the internal structure, density and uniformity of grains of materials.


MHC alloy (molybdenum hafnium carbon alloy) is an upgraded product of TZM molybdenum alloy. Its performance and strength are better than TZM alloy under high temperature conditions. The new MHC alloy developed by Gemi metal has an oxygen content of less than 50ppm, which can be used instead of TZM alloy. Under the high temperature conditions required by special requirements, it can deliver its excellent use effect.

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.

Sinter
From powder to finished products, GeMei strictly controls every process in the production process
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.
