国泰海通｜电子：钛合金持续渗透，国内企业积极布局

Core Viewpoint - Titanium alloys are expected to continue penetrating various applications, driven by advancements in powder metallurgy and 3D printing technologies, which will further expand their usage [1][2][3]. Group 1: Titanium Alloy Applications - The first foldable screen product from Apple is anticipated to be released in 2026, which is expected to significantly increase the demand for titanium alloys due to their high strength, corrosion resistance, and favorable surface texture [3]. - Key applications of titanium alloys in foldable screens include: 1. Middle frame: Titanium alloy frames exhibit superior bending resistance compared to aluminum alloys while achieving lightweight, thus better protecting the screen and internal components [3]. 2. Screen backing: It supports the screen to ensure display quality and touch experience, guiding the screen to bend at specific angles during folding and unfolding, reducing creases. Using pure titanium backing can significantly lower the device's weight, balancing weight, performance, and processing costs [3]. 3. Other applications: Due to better toughness and corrosion resistance, titanium alloys are expected to be used in components like foldable screen axis covers [3]. - The development of 3D printed titanium alloys offers high design freedom, enabling the production of complex hollow or integrated structures that CNC cannot achieve, with gradual applications in aerospace, medical fields, and high-end consumer electronics [3]. Group 2: Domestic Enterprises and Market Demand - Domestic companies are deeply engaged in titanium alloy production and are expected to benefit from a surge in downstream demand [4]. - Powder metallurgy can also be utilized to prepare advanced fusion materials, with domestic enterprises actively overcoming critical bottlenecks. As global demand for sustainable energy grows, the commercialization of nuclear fusion continues to advance [4]. - The materials used in nuclear fusion reactors must withstand extreme conditions, including high-energy neutron irradiation, high temperatures, high heat flux, and strong magnetic fields, necessitating high-performance materials [4]. - Companies like Tiangong International are making significant progress in developing fusion materials through powder metallurgy, including advanced reduced activation ferritic-martensitic (RAFM) steel and high-boron steel for nuclear power, with core applications in shielding layers and vacuum chamber interlayers, which are expected to benefit from the upcoming demand for nuclear fusion [4].
