Abstract

The invention relates to manufacturing of an aluminum alloy, and provides a corrosion resistant aluminum alloy with good corrosion resistance, good comprehensive performance and high strength performance, and the aluminum alloy comprises the following components in percentage by weight: 1.5-1.7% of magnesium, 0.4-0.55% of manganese, 0.05-0.08% of zirconium, 0.1-0.2% of nickel, 1.5-1.7% of copper, 0.4-0.55% of vanadium, 0.05-0.07% of boron, 0.036-0.056% of titanium, 0.35-0.45% of chromium and the balance of aluminum and inevitable impurities.

Description

A kind of anticorrosion aluminium
Technical field
The present invention relates to aluminium alloy manufacture, particularly a kind of anticorrosion aluminium.
Background technology
Because of it, aluminum alloy materials has that density is little, intensity is high and the feature such as reserves are large and in industrial aspect widespread uses such as Aeronautics and Astronautics, naval vessel, building materials, household electrical appliances, telecommunications and power cables, have consequence and effect.The quantity that current aldural uses at industrial circle and increasing extent many, but there is many problems in alloy aluminum of the prior art, corrosion resistance nature is inadequate, cannot meet the aspects such as machine-shaping, surface quality and thermal treatment, this makes to be restricted the use of high-strength aluminum alloy material in industrial circle.
Summary of the invention
Therefore, for above-mentioned problem, the present invention proposes a kind of corrosion resistance and good, good combination property, anticorrosion aluminium that strength property is high.
For solving this technical problem, the present invention takes following scheme: a kind of anticorrosion aluminium, and its composition is by weight percentage: magnesium 1.5-1.7%, manganese 0.4-0.55%, zirconium 0.05-0.08%, nickel 0.1-0.2%, copper 1.5-1.7%, vanadium 0.4-0.55%, boron 0.05-0.07%, titanium 0.036-0.056%, chromium 0.35-0.45%, surplus are aluminium and inevitable impurity.
Further, the rare earth that weight percent is 0.02-0.04% can also be added.
Further, in described inevitable impurity, the weight percent content of iron is less than 0.015%.
By adopting preceding solution, the invention has the beneficial effects as follows: formed and proportioning by optimized alloy, control the content of the especially iron of impurity element in alloy simultaneously, make the excellent anti-corrosion performance of this aluminium alloy, mechanical behavior under high temperature is good, and over-all properties meets the demands.
Embodiment
Aluminum alloy materials is in the inventive solutions produced mainly through hot-work, particularly hot extrusion processing.The techniques such as process for processing in the present invention with existing aluminum alloy production process and device all identical, change be only change to aluminum alloy materials composition, therefore all illustrate no longer one by one in the present invention and following each embodiment.
Embodiment one, anticorrosion aluminium, its composition is by weight percentage: magnesium 1.5%, manganese 0.4%, zirconium 0.05%, nickel 0.1%, copper 1.5%, vanadium 0.4%, boron 0.05%, titanium 0.036%, chromium 0.35%, rare earth 0.02%, surplus are aluminium and inevitable impurity, and in described inevitable impurity, the weight percent content of iron is less than 0.015%.
Embodiment two, anticorrosion aluminium, its composition is by weight percentage: magnesium 1.7%, manganese 0.55%, zirconium 0.08%, nickel 0.2%, copper 1.7%, vanadium 0.55%, boron 0.07%, titanium 0.056%, chromium 0.45%, rare earth 0.04% surplus are aluminium and inevitable impurity, and in described inevitable impurity, the weight percent content of iron is less than 0.015%.
Embodiment three, magnesium 1.6%, manganese 0.5%, zirconium 0.065%, nickel 0.15%, copper 1.6%, vanadium 0.5%, boron 0.06%, titanium 0.046%, chromium 0.4%, rare earth 0.03% surplus are aluminium and inevitable impurity, and in described inevitable impurity, the weight percent content of iron is less than 0.015%.
Embodiment four, magnesium 1.6%, manganese 0.48%, zirconium 0.07%, nickel 0.17%, copper 1.67%, vanadium 0.48%, boron 0.065%, titanium 0.045%, chromium 0.38%, rare earth 0.028% surplus are aluminium and inevitable impurity, and in described inevitable impurity, the weight percent content of iron is less than 0.015%.
Embodiment five, magnesium 1.55%, manganese 0.45%, zirconium 0.058%, nickel 0.13%, copper 1.67%, vanadium 0.45%, boron 0.05-0.07%, titanium 0.042%, chromium 0.42%, rare earth 0.035% surplus are aluminium and inevitable impurity, and in described inevitable impurity, the weight percent content of iron is less than 0.015%.
The present invention consists of and proportioning optimized alloy, and control the content of the especially iron of impurity element in alloy, make the excellent anti-corrosion performance of this aluminium alloy, mechanical behavior under high temperature is good, and over-all properties meets the demands simultaneously.
Although specifically show in conjunction with preferred embodiment and describe the present invention; but those skilled in the art should be understood that; not departing from the spirit and scope of the present invention that appended claims limits; can make a variety of changes the present invention in the form and details, be protection scope of the present invention.
