The processing technology and process innovation of Tungsten Alloys are of great significance for improving the quality of tungsten alloy products, reducing production costs, and expanding application fields. The following will introduce the processing technology and process innovation of tungsten alloy materials from several aspects, including material selection, processing technology, new tools and equipment.Tungsten Alloy Blank

Material selection

The material selection of tungsten based high density alloys is the foundation of processing technology. The commonly used tungsten alloy materials currently include two types: WC Co series and WC Co Ni series. WC Co series alloys have good hardness and wear resistance, but their toughness is poor; The WC Co Ni alloy achieves a good balance between hardness and toughness. With the increasing demand for the performance of tungsten alloy products, the types of tungsten alloy materials are also expanding, such as tungsten rhenium alloys, tungsten iron alloys, etc. Reasonable selection of alloy materials can improve the performance indicators of tungsten alloys by adjusting the ratio and adding appropriate alloy elements.

Processing technology

The processing technology of tungsten alloy mainly includes steps such as powder metallurgy, compression molding, sintering, and precision machining. How to improve the uniformity and flowability of tungsten alloy powder in powder metallurgy process is crucial. Common methods include improving the flowability of powders through measures such as particle size grading and surface treatment. Compression molding is the process of forming tungsten alloy powder, mainly using methods such as unidirectional pressure molding and isostatic pressure molding. How to improve the density, toughness, and wear resistance of the finished product is a key issue in these forming methods. The sintering process involves high-temperature treatment of formed tungsten alloy billets to form a dense block structure. The application of high-temperature sintering and the addition of sintering aids can improve the sintering density and mechanical properties. Precision machining is the mechanical processing of sintered tungsten alloy billets to meet design requirements. Traditional mechanical processing methods include turning, drilling, milling, etc. However, due to the high hardness and difficulty of tungsten alloys, traditional mechanical processing often has poor results and severe wear on tools and equipment. Therefore, in recent years, advanced non-traditional machining technologies have been introduced, such as electric discharge machining, laser machining, ultrasonic machining, etc., to improve machining efficiency and product quality.Tungsten Heavy Alloy Rod

New tools and equipment

In order to meet the processing needs of tungsten alloy materials, it is also important to continuously introduce new tools, cutting tools, and equipment. Firstly, it is necessary to develop tungsten alloy cutting tools. Tungsten alloy cutting tools are widely used in steel processing and other fields, but due to the high hardness and brittleness of tungsten alloy cutting tools, they are often prone to fracture, edge falling, and other situations. Therefore, it is necessary to develop new tool materials and tool structures to improve cutting performance and service life. Secondly, it is necessary to develop suitable grinding tools and fluids for the high hardness and low thermal conductivity of tungsten alloy materials. By optimizing the shape and material characteristics of grinding tools, as well as selecting the type of grinding fluid and additives reasonably, grinding efficiency and finished product quality can be improved. In addition, in order to improve processing efficiency and product quality, it is necessary to develop special composite processing equipment suitable for tungsten alloy materials, such as ultrasonic composite processing equipment, laser composite processing equipment, etc., to meet various complex shapes and high-precision processing needs.

By selecting alloy materials reasonably, optimizing processing techniques, introducing advanced non-traditional processing technologies, and developing new tools, cutting tools, and equipment, the quality and efficiency of tungsten alloy products can be continuously improved. In the future development, it is necessary to continue to increase research and development efforts on tungsten alloy materials, continuously promote processing technology and process innovation, to meet the growing market demand.
