A process for improving the properties of low density aluminum alloys comprises a controlled heat and cooling treatment of a shaped alloy to obtain a product which in the non-aged condition has improved fracture toughness without sacrificing tensile properties. The product is particularly useful for treating forged Al-Li-Mg alloys.

Production of Al alloys with improved properties

Metal flake of improved reflectivity is produced by a method comprising wet ball milling a metal powder in the presence of a lubricant comprising an organometallic compound.

Production of highly reflective metal flake

Metal flake of improved conductivity is produced by a method comprising wet ball milling a powder of a conductive metal in the presence of a lubricant comprising an organometallic compound.

Production of electrically conductive metal flake

A pigment system for electronic and electromagnetic shielding coatings including in percent by weight about 30% to about 70% of a nickel powder produced by decomposition of nickel carbonyl under conditions to provide a powder having a chain-like structure of irregularly shaped particles with an average particle size in the range of about 2 to 4 micrometers (um) and a specific surface area of at least about 0.5 m.sup.2 /g, about 20% to about 60% zinc dust and up to about 40% of an iron-nickel powder produced by codeposition from nickel and iron carbonyl with the proviso that the percentage of nickel powder plus the percentage of nickel-iron powder must be in excess of about 45%.
