Embodiment 1
[0014] Take Ti: 0.2wt% by weight percentage; Zr: 0.15wt%; B: 0.4wt%; Mn: 0.01wt%; Cr: 0.35wt%; Sr: 0.1wt%; After batching, each component is smelted in a melting furnace according to the ratio to obtain an alloy, and then cast into an aluminum ingot by deep well casting. The ingot casting temperature is 725°C, the homogenization temperature is 495°C, and the homogenization time is 8 hours. The aluminum ingot is extruded by the hot extrusion process at an extrusion temperature of 460°C, and extruded into a flat material of 60mm×6mm.
Embodiment 2
[0016] Take Ti: 0.05wt%; Zr: 0.01wt%; B: 0.1wt%; Mn: 0.3wt%; Cr: 0.01wt%; Sr: 0.015wt%; Ce: 0.02wt%; ; After batching, each component is smelted in a melting furnace according to the ratio to obtain an alloy, and then cast into an aluminum ingot by deep well casting. The ingot casting temperature is 700 ° C, the homogenization temperature is 495 ° C, and the homogenization time is 48 hours. The aluminum ingot is extruded by the hot extrusion process at an extrusion temperature of 400°C, and extruded into a flat material of 60mm×6mm.
Embodiment 3
