In this paper, the feasibility of using aluminum alloy 5083 as a replacement for currently used stainless steel SUS 304L on hydraulic gate is evaluated. Relevant properties of these two materials are compared for use in hydraulic gates. Forty common types of hydraulic gates were analyzed through the finite element program PLAXIS 3D Foundation. It shows the weight for most types of hydraulic gates with aluminum alloy 5083 is in the range of 37.6-45.9% of that of stainless steel SUS 304L. At the same time, the cost of gate manufacturing is reduced 39.6-50.5% and cost of maintanence/operation can be reduced at least 18%. These advantages could make aluminum alloy 5083 a better material than the commonly used stainless steel SUS 304L for hydraulic gates.
