The aluminum alloy material comprises the following components by weight percent: 0.3-0.5% of manganese, 1-1.2% of iron, 0.5-1% of magnesium, 0.5-1% 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, 0.001-0.0015% of dysprosium and the balance of aluminum.
Description
Technical field
The invention belongs to metal material field, relate to a kind of aluminum alloy materials, refer to especially a kind of aluminum alloy for air conditioner tube material and preparation method.
Background technology
At present, the material of idle call heat exchanger tube is mainly iron alloy or copper alloy, but because the thermal conductivity of iron alloy pipe is not high, and use the thermal conductivity of copper pipe high, but the cost of copper is also higher, and the ratio of copper is great, increases the overall weight of air-conditioning.
Although the thermal conductivity of aluminium is lower than copper, than high a lot of of the thermal conductivity of iron, and the proportion of aluminium is low, comes instead of copper or iron to make the air conditioner heat exchanging tube with aluminium alloy and has lot of advantages.But existing aluminium alloy is when finally being processed into the tubing of thin-walled, because the ductility of aluminium alloy is lower and occur easily breaking or leakage phenomenon than copper, and the Corrosion Protection of existing aluminum alloy materials is crossed less than requiring.
Summary of the invention
The purpose of this invention is to provide a kind of aluminium alloy air-conditioner tube 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 aluminum alloy for air conditioner tube material, its composition includes by weight percentage, same, the nickel of 0.2-0.5% of the magnesium of the manganese of 0.3-0.5%, the iron of 1-1.2%, 0.5-1%, the zinc of 0.5-1%, 0.1-0.15%, the titanium of 0.01-0.03%, the zirconium of 0.03-0.05%, the yttrium of 0.001-0.003%, the dysprosium of 0.001-0.0015% and the aluminium of surplus.
Described manganese, titanium, zirconium, iron, dysprosium and yttrium join in the aluminium alloy with manganese aluminium, titanium aluminium, zirconium aluminium, iron aluminium, dysprosium aluminium and yttrium aluminium alloy mode respectively.
A kind of Air conditioner pipe of aluminum alloy material preparation method:
The composition of aluminium alloy includes by weight percentage, the titanium of the copper of the magnesium of the manganese of 0.3-0.5%, the iron of 1-1.2%, 0.5-1%, the zinc of 0.5-1%, 0.1-0.15%, the nickel of 0.2-0.5%, 0.01-0.03%, the zirconium of 0.03-0.05%, the yttrium of 0.001-0.003%, the dysprosium of 0.001-0.0015% and the aluminium of surplus are prepared material;
Wherein aluminium, zinc and magnesium are selected high purity aluminium ingot, zinc ingot metal and magnesium ingot;
Be smelted into after aluminium after calculating, zinc, magnesium, nickel, mangal and ferro-aluminium mixed and add successively titanium aluminum alloy, zirconium alloy, dysprosium aluminium alloy and yttrium aluminium alloy behind the liquid and then carry out casting and rolling after the refining.
Described smelting temperature is 750 ± 20 ℃; Refining temperature is 700-730 ℃, and refining time is 1-2 hour; Then holding temperature is cast at 700-720 ℃, and constant temperature is cooled to 500 ± 20 ℃ and is rolled, and keeps the constant temperature cooling in the operation of rolling, final roll forming.
The cooling rate of described constant temperature cooling remains on 1.5-2 ℃/minute.
The beneficial effect that the present invention compares with prior art is:
The aluminium alloy pipe of manufacturing 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.
