Huawei Titanium Alloy Mobile Phone Material Innovation Process

In daily life, from furniture to transportation, to wearable devices, the selection and design of materials are ubiquitous, reflecting the wisdom of designers. In the field of smartphones, the selection and innovation of titanium alloy materials have become the focus of competition for many technology companies. Among them, Huawei's exploration in this field is particularly noteworthy. In 2017, a metal materials expert at Huawei was attracted by the excellent performance of titanium aluminum composite materials in extreme environments while watching a video about aerospace. So he boldly envisioned introducing this high-end technology from the aerospace field into mobile phone manufacturing. Despite their avant-garde ideas, this expert and their team did not back down. They are well aware that in the smartphone industry, material selection is crucial for product competitiveness. Therefore, the team consulted a large amount of information, conducted countless experiments and tests, and finally successfully demonstrated the application scheme of titanium aluminum composite materials in mobile phones, and obtained national patents. In order to further enhance the reliability of the product, another team at Huawei has introduced the "hot isostatic pressing" technology, successfully combining different types of metals to achieve maximum material utilization. This is a cross-border innovation that successfully applies aerospace grade titanium aluminum composite technology to mobile phone manufacturing, filling the gap in this field in China. However, the path of innovation is not smooth sailing. In the practical application of titanium aluminum composite materials, the team encountered the problem of exceeding the initial blank antenna seam size, which seriously affected the reliability of the entire machine. In the face of difficulties, the team did not give up, but conducted a comprehensive investigation and trial, and finally successfully solved the problem by increasing the initial gap, further improving the reliability of the material. On this basis, the team was not satisfied and decided to challenge a higher goal - to create a titanium alloy with a bright appearance. By drawing inspiration from jewelry grade polishing techniques and undergoing multiple meticulous polishing processes, they have successfully created a unique glossy titanium alloy. This material not only makes the phone more sturdy and durable, but also effectively solves the problems of wear, scratches, and dirt that may occur in daily use. After a series of rigorous tests, this new material has demonstrated excellent reliability: its wear resistance has increased by five times, and its drop resistance has also doubled compared to its predecessor. At this point, Huawei's high brightness titanium alloy architecture has finally been developed, bringing consumers an unprecedented ultimate product experience. This achievement not only demonstrates Huawei's profound foundation in the field of materials science, but also embodies its spirit of daring to challenge and innovate.
