In the field of lightweight material research and development, the industrial application of the aluminum-titanium intermediate alloy additive AlTi5 has attracted industry attention. As an important member of the aluminum-based intermediate alloy family, this additive successfully solved the problem of grain coarsening in traditional aluminum alloy casting by precisely controlling the distribution of titanium elements, providing a new material solution for the manufacturing of aerospace and new energy vehicle components.
Industry experts have pointed out that the combined use of aluminum alloy fluxes and intermediate alloys is becoming a key factor in process upgrading. AlTi5 innovatively integrates the dual functions of grain refinement and melt purification - its unique core-shell structure can not only serve as a particle refining agent to directionally correct the solidification structure, but also simultaneously replace part of the purification fluxes, significantly reducing gas inclusions during the smelting process. Currently, this technology has been applied in the casting of new energy battery trays, demonstrating excellent fatigue resistance characteristics.
With the increasing demands for material properties in the manufacturing industry, the functionalization of aluminum-based intermediate alloys has been accelerating continuously. Compared to single-type additives, composite functional materials such as AlTi5 can not only be used in conjunction with conventional aluminum alloy fluxes, but also be embedded as independent particles as a refining agent in digital casting systems. Several leading enterprises have reported that their introduction has achieved breakthrough improvements in the yield and surface finish of high-strength aluminum materials. In the future, aluminum-titanium alloy additives with both melt modification and structural strengthening properties may become an important driving force for the iterative development of lightweight technology.
