Lifting Gas in a world with 1/3 of earth's gravity

As many of us probably know airships were one of the great forms of transportation in the 20th century but a great hindrance to their development was weight. In a world I am currently constructing the gravity is 1/3 as that on earth so metals and material are lighter but have the same strength as on our world. They are so light that steel weighs the same as aluminum here on earth and can be used in airship construction. Because of the reduced gravity airships can now carry bigger loads per same volume of gas here on earth but there is one detail that eludes me. Would lifting gas have 3 times the lift per 1,000 cubic feet in this lower gravity environment or would it stay the same as here on earth? Note that although the gravity is 1/3 the atmosphere is the same pressure, density and composition as here on earth. Also would metal retain the same strength in a lighter gravity world as I do not know the effects of lighter gravity on metal production.
