Metali is a high-tech enterprise driven by nanotechnology for large-scale manufacturing and production of aluminum alloys. The world's first nano metallurgical technology has successfully achieved a historic breakthrough in the castability, weldability, and printability of deformed aluminum alloys (7 series, 6 series, 5 series, 3 series, and 2 series). Solved the century old problem of solidification forming and low efficiency and high cost of high-strength aluminum alloys represented by 7075, 6063, etc. Widely used in aerospace aluminum alloy die-casting, nano aluminum alloy castings, alumina die-casting, aluminum alloy casting, involving fields such as aerospace, automotive, transportation, vehicles, aircraft, optical communication, mobile electronics, e-bikes, and high-strength sports equipment that require high strength, high thermal conductivity, high electrical conductivity, color anodizing, and other structural requirements. Nano aluminum alloy welding materials include high-strength aluminum alloy arc additive and nano aluminum alloy 3D printing powder. Maite Li will continue to use nanotechnology as the core driving force to break the limits of traditional metal production, processing, and manufacturing, leading the new era of large-scale production and manufacturing of nano metals.
