the sinking and floating at water doesn't depend on the material we use but on the shape we mould that particular material.all the objects placed in a liquid experience an upward force which allows the body to float if it displaces water with the weight equal to the weight of the body. This upward force is known as buoyant force and the law is known as the law of buoyancy. Mainly, floatation depends upon the density.
