Abstract
The invention relates to an alloy material for a mower and a preparation method thereof. The alloy material comprises the following components in percentage by weight: 0.3-0.5% of manganese, 1-1.2% of iron, 0.5-0.8% of magnesium, 6.5-7.0% of zinc, 0.1-0.15% of copper, 0.2-0.5% of nickel, 0.01-0.03% of titanium, 0.03-0.05% of zirconium, 0.001-0.003% of yttrium and the balance of aluminum. The aluminum alloy pipe material has the advantages of high strength, high ductility and higher corrosion resistance; and the cost is much lower than that of the copper pipe, but the properties are similar to those of the copper pipe and much superior to those of the iron pipe.
Description
Technical field
The invention belongs to metal material field, refer to especially aluminum alloy materials and preparation method for a kind of mower.
Background technology
Present stage, aluminium alloy extrusions is lightweight with it, high ductibility, has high-intensity performance even simultaneously, is widely used.But in the application of this class section bar, particularly in casting or extrusion processing process, a series of reasons such as aluminium alloy interior tissue can be because stress changes greatly, and temperature rise is large can cause occurring in the quenching process after moulding crystal grain recrystallize phenomenon.Excessive grain growth in organizer, forms coarse grain.This class crystal grain all has a great impact the processing in the mechanical property of aluminum alloy materials, anti-fatigue performance, corrosion resistance and later stage.
Summary of the invention
The object of this invention is to provide a kind of aluminium alloy mower material, the ductility of described aluminium alloy is higher than existing aluminium alloy, and can keep enough intensity, and Corrosion Protection improves.
The present invention is achieved by the following technical solutions:
A kind of mower alloy material, its composition is by weight percentage, the manganese of 0.3-0.5%, the iron of 1-1.2%, the magnesium of 0.5-0.8%, the copper of the zinc of 6.5-7.0%, 0.1-0.15%, the titanium of the nickel of 0.2-0.5%, 0.01-0.03%, the yttrium of the zirconium of 0.03-0.05%, 0.001-0.003% and the aluminium of surplus.
Described manganese, titanium, zirconium, iron and yttrium join in aluminium alloy with manganese aluminium, titanium aluminium, zirconium aluminium, iron aluminium and yttrium aluminium alloy mode respectively.
Described preparation method:
The composition of aluminium alloy includes by weight percentage, the manganese of 0.3-0.5%, the iron of 1-1.2%, the magnesium of 0.5-0.8%, the copper of the zinc of 6.5-7.0%, 0.1-0.15%, the titanium of the nickel of 0.2-0.5%, 0.01-0.03%, the yttrium of the zirconium of 0.03-0.05%, 0.001-0.003% and the aluminium of surplus, prepare material;
Wherein aluminium, zinc and magnesium are selected high purity aluminium ingot, zinc ingot metal and magnesium ingot;
After being smelted into liquid after aluminium, zinc, magnesium, nickel, mangal and ferro-aluminium after calculating are mixed, add successively titanium aluminum alloy, zirconium alloy and yttrium aluminium alloy then to carry out casting and rolling after refining.
Described smelting temperature is 750 ± 20 ℃; Refining temperature is 700-730 ℃, and refining time is 2 hours; Then holding temperature is cast at 700-720 ℃, and constant temperature is cooled to 500 ± 20 ℃ to be rolled, and keeps constant temperature cooling in the operation of rolling, final roll forming.
The cooling cooling rate of described constant temperature remains on 15-20 ℃/min.
The present invention's beneficial effect is compared with the existing technology:
The aluminium alloy pipe of manufacture of the present invention also has height when having same intensity and lifts ductility, and corrosion resistance nature is higher; Cost is far below copper pipe, and the gap of performance and copper pipe is not much better than iron pipe very much.
