Abstract
The invention relates to an alloy material for an automotive water tube, comprising the following constituents by weight percent: 0.3-0.5% of manganese, 2-2.5% of iron, 0.5-1% of magnesium, 10-15% of zinc, 5-8% of copper, 0.03-0.05% of zirconium, and the balance of aluminium. The alloy tube manufactured from the alloy material disclosed by the invention is high in strength, ductility and corrosion resistance; the cost of the alloy tube is far lower than that of a copper tube; and the performance of the alloy tube approximates to the that of the copper tube and is far superior to that of an iron tube.
Description
Technical field
The invention belongs to metal material field, refer to especially a kind of automobile-used water pipe alloy material.
Background technology
At present, automobile-used water pipe alloy material is mainly iron alloy or copper alloy, but because iron alloy pipe gentle not high, and use copper pipe cost also higher, and the ratio of copper is great, increases the overall weight of vehicle.
Aluminium proportion low, come instead of copper or iron to make automobile-used water pipe with aluminium alloy and have 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.
But consider automobile-used water pipe to the requirement of intensity and heat transfer efficiency, and consider that from the thinking that alleviates vehicle weight aluminium alloy is optimal selection simultaneously.But for the ductility, intensity and the high heat conduction validity that increase aluminium alloy are set out, the alloy that uses in the existing technology is for adding precious metal element and the rare earth element that improves intensity and toughness take aluminium element as the master and in alloy, such selection has not had difference or ratio only taller with the cost of copper product with the cost that uses copper product.
Summary of the invention
The purpose of this invention is to provide a kind of automobile-used water pipe alloy material, the ductility of described alloy is higher than existing aluminium alloy, and proportion is lower than copper, and can keep enough intensity, and Corrosion Protection is higher and do not use or reduce and use precious metal or rare earth element.
The present invention is achieved by the following technical solutions:
A kind of automobile-used water pipe alloy material, its composition includes by weight percentage, the copper of the magnesium of the manganese of 0.3-0.5%, the iron of 2-2.5%, 0.5-1%, the zinc of 10-15%, 5-8%, the zirconium of 0.03-0.05% and the aluminium of surplus.
Described manganese, zirconium, iron join in the aluminium alloy with mangal, zirconium alloy, ferro-aluminium mode respectively.
Described alloy material preparation method:
The composition of alloy includes by weight percentage, and the copper of the magnesium of the manganese of 0.3-0.5%, the iron of 2-2.5%, 0.5-1%, the zinc of 10-15%, 5-8%, the zirconium of 0.03-0.05% and the aluminium of surplus are prepared material;
Wherein aluminium, zinc, copper and magnesium are selected high purity aluminium ingot, zinc ingot metal copper ingot and magnesium ingot;
Be smelted into after aluminium after calculating, zinc, magnesium, copper, mangal and ferro-aluminium mixed to add behind the liquid and carry out casting and rolling after the refining behind the zirconium alloy.
Described smelting temperature is 850 ± 20 ℃; Refining temperature is 950-1050 ℃, and refining time is 1-2 hour; Then holding temperature is cast at 850-870 ℃, 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 2.5-3 ℃/minute.
The beneficial effect that the present invention compares with prior art is:
The 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.
