ABSTRACT:
An aluminum alloy with excellent decorativeness, having a composition represented by the general formula AlaMgbMncCrd, wherein b, c, and d are, in mass percentage, 3.0≦b≦5.6, 0.05≦c≦1.0, 0.05≦d≦0.7, c+d>0.2, and a is the balance with unavoidable impurity elements possibly being contained, wherein a matrix of the aluminum alloy is a structure substantially composed of an aluminum solid solution, in which no β-phase is present. This alloy has excellent decorativeness and decorativeness as well as superior strength, hardness and other such mechanical properties and is useful as materials for slide fastener constituent members, such as their elements, stops, and sliders, and/or in snap buttons, ordinary buttons, and clasps.
