My invention relates to an improved aluminium alloy which while retaining the properties of aluminium so far as regards weight, color, ductibility, and resistance to oxidation, has such increased resistance as will permit of its use in many cases as a substitute for iron or steel.
The metal can be rolled, formed, stamped, and drawn as easily as mild steel.
The alloy consists of the following metals in the proportions given :copper, 0.375; tin, 0.105; antimony, 1.442; Wolfram, 0.038; aluminium, 98.040; total, 100.000.
The metals are mixed in the order in which they are given, a small quantity of aluminium being added with each successive metal to act as a flux and facilitate its admixture. When i REINHARD ISIDORE ROMAN.
