Slab solar aluminum alloy cladding layer containing rare earth element

The invention discloses a slab solar aluminum alloy cladding layer containing a rare earth element. A cladding layer material is prepared through raw materials, in the following mass proportion, including 0.5%-1.0% of Ni, 1.0%-2.0% of Fe, 0.1%-1.0% of Mn, 0.65%-0.75% of La, 0.1%-0.6% of Ce, 0.2%-0.3% of Zr and the balance aluminum. The cladding layer material is simple in preparing method, good inbonding with a base body and not prone to fall; and the prepared aluminum alloy cladding layer is attractive, good in corrosion resistance and abrasive resistance, high in strength and ductility andhigh in heat absorbing and transferring capacity. 本发明公开了种含稀土元素的平板太阳能铝合金镀层，镀层材料由以下质量比例的原料制得：0.5～1.0%Ni、1.0～2.0%Fe、0.1～1.0%Mn、0.65～0.75%La、0.1～0.6%Ce、0.2～0.3%Zr，余量为铝。本发明镀层材料制备方法简单，与基体结合好，不易脱落；制备的铝合金镀层美观，耐腐蚀性和耐磨性好，强度和延展性高，吸热传热能力强。
