A corrosion-resistant clad material is made of aluminum alloys, and in a preferable mode, comprises: a core which is either formed of an Al-Mn alloy containing 0.5 - 1.5 % by weight of Mn; or alternatively formed of an Al-Mg-Si alloy containing 0.05 - 1.0 % by weight of Mg and 0.05 - 0.3 % by weight of Si. The Al-Mn alloy and Al-Mg-Si alloy further contain, as additional components, 0.05 - 0.3 % by weight of Ti and/or 0.05 - 0.4 % by weight of Zr. The clad material further comprises skin layers which are formed of an Al-Zn alloy clad onto at least one surface of the core. In another preferable mode, the clad material comprises: a core formed of an Al-Mn alloy containing 0.5 - 1.5 % by weight of Mn; and skin layers clad onto at least one surface of the core and formed of an aluminum alloy containing 1.3 - 5.0 % by weight of Zn, with or without 0.2 - 1.0 % by weight of Mg, and a balance of aluminum and unavoidable impurities. Cu content as one of the impurities is controlled to 0.05 % by weight or less, with the skin layers having a thickness of 30 µm or less.
