Tungsten Alloy High Pressure Nozzle MIM Parts

Product Description

An important component of an aerospace engine is the tungsten alloy nozzle. There are various materials for making nozzles. Why choose tungsten alloy only? What are the advantages of tungsten alloy nozzles? Let's walk into the tungsten alloy nozzle together and see its strength.

Tungsten alloy nozzle is a kind of tungsten as the main raw material, which has high melting point, high hardness, high density, high temperature resistance, corrosion resistance, wear resistance, impact resistance, good chemical stability and plasticity, etc., especially made of tungsten-rhenium alloy nozzle parts.

In aerospace engines, nozzles need to work under harsh conditions such as high temperature, high pressure, high speed and strong vibration for a long time. The extreme working environment also requires that the raw materials for the preparation of nozzle inserts should have the characteristics of high melting point, low thermal expansion coefficient, strong heat dissipation capacity, good mechanical properties and ductility, otherwise the use effect and service life of the product will be poor, and then It is very likely to cause the device to fail to start.

Tungsten alloy nozzles can adapt to various working conditions, so they are widely used in aerospace, aviation, military, national defense, semiconductor, welding and other fields. For the production and processing of tungsten alloy nozzles, Qinhuangdao Zhongwei Precision has a strong strength, advanced and complete equipment, including presses, sintering furnaces, imported CNC lathes, grinding machines, milling machines, etc.

Tungsten alloys and cemented carbides with tungsten as the main raw material have unique performance advantages in many applications, and are indispensable materials in industries such as national defense, aerospace, metal processing, mining, and oil drilling. With the development of civilian industries such as modern national defense, aerospace and electronic processing, and transportation, tungsten alloys and cemented carbides are being used more and more widely, and the development of modern technology requires more and more complex shapes of alloy parts. The higher the manufacturing cost, the lower the manufacturing cost. For example, in recent years, cemented carbide has been widely used in wear-resistant parts such as watch cases, high-pressure nozzles, and sawtooth chains. , mobile phone vibrators, fish pendants, etc. are also being used more and more widely. These parts are often complex in shape, usually with holes, grooves, variable cross-sections, etc., which requires tungsten alloy and cemented carbide parts to 3D shape design freedom development.

The application advantages of PIM process in refractory tungsten alloy and cemented carbide are mainly reflected in the following aspects:

(1) Tungsten alloy and cemented carbide have high melting points and can only be prepared by powder metallurgy, which determines the uniqueness and inevitability of using powder mixing method to prepare parts.

(2) Refractory tungsten alloys and cemented carbides have high hardness, high brittleness, poor conductivity, and difficult cutting. The increase in the complexity of the shape will greatly increase the cutting cost of traditional P/M products.

(3) The shape of cemented carbide and tungsten alloy parts prepared by the traditional P/M method is limited and cannot meet the requirements of shape complexity.

(4) PIM technology has a large degree of freedom in three-dimensional shape design.

(5) The raw material utilization rate of PIM products is high, which is very important for tungsten alloy and hard alloy whose raw materials are more and more expensive.

(6) Tungsten is a strategic material, and tungsten resources are becoming more and more limited. In order to make full use of tungsten resources and raw materials, the deep processing technology of tungsten products has a broad development and application prospect.

It can be seen that the use of PIM technology to prepare tungsten alloy and cemented carbide products has unparalleled advantages over other materials, and it has a very broad development space in military, aerospace and civilian industries.
