ALUMINIUM ALLOY Russian patent published in 2018 - IPC C22C21/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, particularly to aluminum alloys, and can be used for manufacturing high-loaded brazed structures. Aluminum alloy contains, % by weight: 0.5–0.8 of silicon, 0.5–0.9 of magnesium, 0.05–0.3 of copper, 0.05–0.2 of chromium, 0.15–0.25 of iron, 0.005–0.02 of titanium, 0.1–0.2 of zirconium, 0.05–0.35 of molybdenum, aluminum is the remainder, while copper is completely bound to secondary precipitates of Al₅Cu₂Mg₈Si₆ phase, the material solidus temperature is not less than 600 °C.

EFFECT: invention is aimed at increasing the strength of brazed structures and blanks, which leads to increased service life of products.
