The role of controlled expansion alloys

The role of controlled expansion alloys

A precision alloy with abnormal thermal expansion characteristics, also known as controlled expansion alloy, is widely used in the fields of electronics industry, precision measuring tools, precision instruments and low temperature engineering. In addition to a specific thermal expansion coefficient, the expansion alloy also requires good sealing, weldability, corrosion resistance, machinability and ease of machinability according to different uses, and it is not allowed to cause expansion within the operating temperature range. A distinct phase transition. The chemical composition of the expanded alloy must be accurately controlled during the manufacturing process, and its products are generally rods, plates, strips, wires and pipes.

Tianjin Zuoyuan New Material Technology Co., Ltd. is a high-tech company specializing in the research of advanced metal material preparation technology and the development, production and sales of high-performance metal materials. With the valuable experience accumulated over the years in the field of non-ferrous metal development and the integration of advanced automation control technology, Zhongyuan has achieved remarkable results in the field of high-performance metal materials and has become an innovative enterprise with strong competitiveness in this field. The superhard aluminum alloys and high wear-resistant aluminum alloys developed by the company have been successfully applied in high-end fields such as aerospace, satellite communications, and auto parts industries.

We have a rapid solidification process, which is further optimized on the basis of the spray molding process (also known as spray deposition), which is similar to the atomization pulverization process, which sprays molten, atomized metal onto a rotating substrate , the metal forming process of forming metal ingots or billets. . This process has a high solidification rate and a relative density of over 99.2%. After hot working (forging, rolling, extrusion or HIP), the material is processed into a dense product.

Yes. All AlSi alloys can be machined easily, such as CNC, EDM, wire cutting etc.
