A powdered alloy with a chemical composition of AlSi, where X is an amount of Si from 10 to 30 weight percent. More specifically, a powdered alloy with a chemical composition of AlSiSnIn, where X is an amount of Si from 10 to 30 weight percent, Y is an amount of Sn from 0.01 to 0.50 weight percent, and Z is an amount of In from 0.005 to 0.05 weight percent.

Embrittled aluminum alloys for powder manufacturing

A method of creating aluminum powder, the method comprising of blending and melting aluminum of a purity from about 99% to about 99.999% with an embrittling element or combination of embrittling elements selected from the group consisting of silicon in the amount of 1 to 30% by weight and germanium; mixing together the melted aluminum and embrittling elements such that an alloy is created; cooling the mixed alloy; cutting the cooled alloy into smaller pieces; crushing the cut pieces; and, pulverizing and milling the crushed pieces into particles with a size of less than 200 micrometers.

The invention comprises synergistic compositions of at least one metal polycarboxylate and lithium phosphate. The synergistic compositions are designed to be added to film-forming or other compositions to reduce the corrosion of various metal surfaces or substrates on which the synergistic compositions are applied.

Synergistic corrosion inhibitor compositions

The invention comprises synergistic compositions of at least two metal carboxylates as corrosion inhibitors based on polycarboxylate anions and a variety of different cations. The inhibitors are designed to be added to film forming or other compositions to reduce the corrosion of the metal substrate on which the synergistic compositions are applied.
