摘要

A corduro method make castings with aluminum alloys, which have a high physical strength, which method includes the operations of mixing and casting together from 4.2% to 6% by weight approximately of copper, from 0.05% to 3% about silver, and a grain refiner, the rest being mainly aluminum, fill a mold with the mixture of said metals, heat the castings for about 3 to 4 hours at a temperature between 526ºC to 540ºC approximately and temper the treated pieces thermally aging them for at least 8 hours at a temperature above about 137º C.
