Taigang Ni36 replaces imported wing mold manufacturing in bulk supply
A few days ago, China’s Baowu Taiyuan Iron and Steel Co., Ltd. reported that the company signed a bulk order for Ni36 nickel based alloy with a domestically-made large aircraft project supporting mold manufacturer, and became the designated supplier. The products will be used to make wing molds for my country’s CR929 models. . This marks the realization of a stable batch supply of nickel-based alloys for aviation molds of Taiyuan Iron and Steel, and the realization of the import substitution of this product.
It is understood that the Ni36 material for aerospace molds is also called Invar. It is a nickel-iron alloy containing 36% nickel. Because of its special performance that it does not expand within a certain temperature range, it is widely used in aerospace and other temperature-sensitive alloys. Fields with strict deformation requirements. However, due to the difficulty of its production, it has been dependent on imports for a long time, restricting the development of my country’s aviation industry.
Facing the urgent demand for high-end nickel-based alloy materials in the domestic military, aerospace, 5G communications, electronic circuits and other industries, Taiyuan Iron and Steel took active actions and carefully researched and developed Ni36 materials after 10 years. Some performance indicators are better than imported materials. The delivery is stable and fast, making an important contribution to the localization of key materials in my country’s aviation industry.
At present, the 800 series and 600 series nickel-based alloy products developed by Taiyuan Iron and Steel Co., Ltd. have formed a full range of shapes, wires, plates, tubes, and strips. In the future, TISCO will make unremitting efforts for the localization of basic materials in the fields of aero engines, landing gears, and supporting welding wires.
