Embodiment 1
[0041] According to the chemical composition requirements of the aluminum-clad substrate involved in the present invention, steel strips 1 and 0.2mm aluminum strips 2 of different specifications are selected for single-layer compounding, see figure 1 , Rolling at room temperature after surface cleaning and grinding. The chemical composition of the aluminum-clad substrate is shown in Table 1. The aluminum-clad strip is bell-type annealed, and the thickness of the finished product is 0.3-4mm. The properties of the finished product are shown in Table 2.
Embodiment 2
[0043] According to the chemical composition requirements of aluminum-clad substrates in Table 1, steel strips 1 and 0.2mm aluminum strips 2 of different specifications are selected for double-layer compounding, see figure 2 , Rolling at room temperature after surface cleaning and grinding. The thickness of the finished product is 0.3-4mm, and the performance of the finished product is shown in Table 3.
[0044] The yield strength of the aluminum-coated steel sheet in the embodiment obtained according to the design scope of the steel grade composition of the invention and the rolling process control technology is 200-320MPa, the tensile strength exceeds 340MPa, and the elongation is above 35%. The steel-aluminum interface bonding performance is excellent, and has good Excellent cold bending and stamping performance. It can be applied to the manufacture of heat dissipation requirements such as wheels, radiator parts and corrosion resistance requirements.
