Abstract

The invention discloses corrosion-resistant aluminum alloy. The corrosion-resistant aluminum alloy is composed of, by weight, 2-5 parts of Si, 2-3 parts of Fe, 10-14 parts of Cu, 1-2 parts of Mn, 10-12 parts of Mg, 58-80 parts of Zn, 0.5-2 parts of Ti, 2-6 parts of rare earth, 1-5 parts of Cr, 1-5 parts of Ni, and the balance Al and irremovable impurities. The corrosion-resistant aluminum alloy is prepared through hot extrusion and quenching treatment and has the beneficial effects that the corrosion-resistant aluminum alloy is high in strength, hardness and corrosion resistance, capable of meeting the requirement of corrosion conditions in the modern environment, low in cost and easy to popularize, and material manufacturing is convenient.

Description

A kind of anticorrosion aluminium

Technical field

The present invention relates to a kind of anticorrosion aluminium.

Background technology

Aluminum and aluminium alloy processing industry enter a brand-new high-speed developing period, and the application of aluminium is more and more extensive, and transportation has become the first large user of aluminium. Aluminium is light-weighted preferred material, and inevitable part substitutes iron and steel becomes the important foundation material of each department of national economy and people's lives each side; Aluminum industry is rising industry, one of mainstay industry that certainly will become materials industry. Domestic and international aluminum and aluminum fabrication industry scale and production technology develop quickly, reach an at a relatively high level, build up the modernization Aluminum group company of large quantities of advanced person, have developed large quantities of Novel aluminum alloy material with various performance and function, different cultivars and purposes; The casting of aluminium oxide, electrolytic aluminium, aluminium alloy, founding, rolling, extruding, tube rolling, draw dial, forging and stamping, powder process, deep processing and detection technique constantly push away newly, to energy-saving and cost-reducing, Environmental Safety, simplify direction continuous, efficient, high-quality, high-grade and develop, have developed large quantities of large-scale, accurate, compact, efficient, energy-conserving and environment-protective, aluminum multi-functional, full automatic and aluminum processing technology equipment, aluminum is greatly facilitated and aluminum processing industry develops to modernization direction. Currently, China's aluminum industry is also faced with the change that a field depth is carved, and enters the period of a unprecedented violent differentiation, adjustment, restructuring and great development, and enterprise's polarization, the process selected the superior and eliminated the inferior will greatly accelerate. Maximization, grouping of the world economy, scale, modernization and internationalization become one of important symbol of modern aluminum and aluminum processing enterprise. Industry and product will adjust energetically, and the system of enterprise and mechanism will be constantly brought forth new ideas, and technological progress is accelerated, and management develops to modernization, automatization, informationization, scientific, efficient and integrated direction, the world.

Our times environment worse becoming, in air, corrosive gas gets more and more, the extent of corrosion of material is become increasingly stronger, and common aluminum alloy materials can not meet modern industry and become the requirement produced, and is therefore badly in need of the technology of a kind of improvement to solve above-mentioned technological deficiency.

Summary of the invention

The invention provides a kind of anticorrosion aluminium.

The technical scheme that the present invention is directed to above-mentioned technological deficiency proposed is:

A kind of anticorrosion aluminium, adds each element in parts by weight, and its composition is: Si:2-5 part, Fe:2-3 part, Cu:10-14 part, Mn:1-2 part, Mg:10-12 part, Zn:58-80 part, Ti:0.5-2 part, rare earth: 2-6 part, Cr:1-5 part, Ni:1-5 part, surplus is Al and not removable impurity, makes through hot extrusion and Quenching Treatment.

Co:1-5 part can also be added.

B:1-3 part can also be added.

The invention has the beneficial effects as follows: intensity is high, hardness is high, and corrosion resistance is strong, can meet the corrosion condition in modern environment, and material is easy to make, and cost is less, it is easy to promote.
