Abstract
An aluminium alloy is provided which consists of 2 to 12% by weight of chromium, 0.2 to 3.0% by weight of iron, the balance being aluminium apart from minor proportions of impurities and incidental elements wherein most of the chromium is present as a metastable solution in the aluminium lattice which contains a precipitate phase of iron rich zones the major proportion of which have dimensions of 200A or less, the presence of large intermetallic particles, particularly at grain boundaries, being at a minimum. This alloy may be produced by an evaporation deposition process.
