What is the process of tungsten alloy powder metallurgy?


  tungsten alloy powder metallurgyIt is made of powder or metal powder (or a mixture of powder and non-metallic powder) as raw materials, through and, making metal materials, composite materials and various types of industries. Powder metallurgy is widely used in transportation, electronics, aerospace, weapons, biology, new energy, information, nuclear industry and other fields, and has become one of the dynamic fields in new material science. Tungsten alloy powder metallurgy has considerable energy saving, saving, characteristics, accuracy, stability and other advantages, suitable for large-scale production. In addition, materials and complex parts that cannot be made by conventional casting and preparation can also be made by powder metallurgy, thus attracting attention from the industry.


The generalized tungsten alloy powder metallurgy industry includes iron and stone tools, cemented carbide, magnetic materials, powder metallurgy, etc. The narrow tungsten alloy powder metallurgy industry refers to powder metallurgy, powder metallurgy parts (most), oil bearings, metal injection, etc.

The process of tungsten alloy powder metallurgy is basically as follows:


1. Production of tungsten alloy powder metallurgy raw material powder. Traditional crushing can be roughly divided into two categories: physical and chemical. Can be divided into crushing and atomization. Physical chemistry is divided into electrochemical corrosion, reduction, chemical, reduction-chemical, vapor deposition, liquid deposition, electrolysis, etc. Among them, reduction, atomization and electrolysis are widely used.


2. Use the required blank powder. The purpose is to make the size, so that it has and strength. It is basically divided into pressurized and non-pressurized. Pressurization is commonly used in. Embryos can also be made using 3D printing.


3, billet. It is the core of tungsten alloy powder metallurgy. Judgments are divided into unit system awards and system awards. For solid phases in the system of units and systems, the temperature is lower than that of the metals and alloys used. For the liquid phase of the system, the temperature is generally lower than that of the insoluble component and higher than that of the easily soluble component. In addition to general, there are special processes such as invoices, melting and dipping, and hot pressing.


  4、tungsten alloy powder metallurgyPost-processing. Post-treatment can take a variety of forms according to requirements. Such as finishing, soaking, heat treatment, electroplating. In addition, in recent years, rolling, forging and other new processes are also suitable for powder metallurgy materials, and have achieved ideal results.

What is the difference between injection and injection in metal injection molding?

Metal injection molding, also known as injection molding, is a molding method that has both injection and molding. The invention has the advantages of fast production speed, high efficiency, automatic operation, diverse colors, simple to complex shapes, and large to small sizes. Moreover, the product size is accurate, the product is easy to update, and it can be made into parts with complex shapes. Metal injection molding is suitable for mass production, complex shape products and other molding processing fields.

What are the characteristics of tungsten alloy powder metallurgy?

Tungsten alloy powder metallurgy is the production of powder or powder (or powder and non-powder mixture) as raw materials, after molding and sintering, production, composite and various types of objects process. The powder metallurgy method is similar to that of powder sintering, so a series of powder metallurgy can also be used for the production. Due to the advantages of powder metallurgy, it has become the key to solve the problem and plays an important role in the development of our powder metallurgy industry.
