Abstract: Aluminum alloy intended more particularly for the manufacture of enamelled articles having good characteristics in the annealed state and excellent behavior of the enamel, the aluminum alloy having the following composition:Si: 1 to 1.5%at least one of the elements of the group Fe-Ni-Co in a total quantity between 0.3 and 2%at least one of the elements of the group Mo-Nb-Ta in a total quantity between 0.05 and 1%Cr: 0.05 to 0.2%Cu: <0.02%Mg: <0.01%the remainder being aluminum with the standard impurities.

Abstract: A steel part, and more particularly a stainless steel part, is coated with a varnish containing particles of an additional metal such as tin or aluminium, and it is heated at a temperature situated above the melting point of the said additional metal, but outside a zone comprised between 700.degree. C and 970.degree. C. The treated part may be annealed at about 500.degree. C. The varnish may besides contain particles of a substance having a melting point situated above the melting point of the additional metal, but which may dissolve in the liquid phase of the latter. This substance may be chromium, molybdenum, cobalt, titanium, vanadium, nickel or copper.
