Abstract
The invention relates to a high-strength low-piece-weight aluminum alloy bicycle pipe which is cast from aluminum alloy. The bicycle pipe is characterized in that the aluminum alloy consists of the following elements in percentage by weight: 0.7-0.9% of Si, less than or equal to 0.5% of Fe, 0.8-1% of Cu, less than or equal to 0.1% of Mn, 1.3-1.5% of Mg, less than or equal to 0.05% of Zn, less than or equal to 0.1% of Ti, 0.13-0.3% of V and the balance being Al and inevitable impurities. By introducing the Zn and the V to the aluminum alloy which serves as a casting material, a primary battery can be formed by the bicycle pipe with the addition of the active Zn element on one aspect, so as to avoid the corrosion of Fe element in the aluminum alloy and to improve the service life and the strength of the bicycle pipe, and a refractory V-Ti alloy body can be formed with the Ti with the addition of the V element on the other aspect and the alloy body can be uniformly dispersed in the aluminum alloy, so that the strength and the corrosion resistance are effectively improved.
Description
Technical field
The invention belongs to metal material field, relate to a kind of bicycle tube, be specifically related to a kind of high strength low substance Al-alloy bicycle tubing.
Background technology
Aluminium alloy is the extension product of fine aluminium, the little (ρ=2.7g/m of density of fine aluminium
3), be approximately 1/3 of iron, and fusing point is low, is about about 660 DEG C, aluminium is face-centred cubic structure, therefore has very high plasticity (δ: 32 ~ 40%, ψ: 70 ~ 90%), and therefore it is easy to processing, can be made into various section bar, sheet material, and corrosion resistance is good.But the intensity of fine aluminium is very low, therefore should not make structured material, by long-term production practice and scientific experiment, people are gradually to add alloying element and to use the methods such as thermal treatment to carry out reinforced aluminum, and this just obtains a series of aluminium alloy.
But easily there is cold shut in existing aluminum alloy surface, the modal product bad phenomenon such as crackle, this product is bad, although the molding parameter by adjusting pressure die-casting machine, the means such as adjustment die temperature control, and effect is also not obvious; And its intensity is lower relative to steel alloy, therefore while the advantages such as maintenance fine aluminium light weight, making it have higher intensity is the target that slip-stick artist pursues, so just manufacturing structure material be can use it for, machinofacture, Transport Machinery, power machine and the aspect such as aircraft industry, bicycle tube are widely used in.
Summary of the invention
The present invention seeks to provide a kind of high strength low substance Al-alloy bicycle tubing to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the present invention is: a kind of high strength low substance Al-alloy bicycle tubing, and it is cast by aluminium alloy and forms, and it is characterized in that: the element weight percent of described aluminium alloy is as follows, Si:0.7 ~ 0.9%, Fe :≤0.5%; Cu:0.8 ~ 1%; Mn :≤0.1%; Mg:1.3 ~ 1.5%; Zn :≤0.05%; Ti :≤0.1%; V:0.13 ~ 0.3%; Surplus is Al and inevitable impurity.
Optimally, the element weight percent of described aluminium alloy is as follows, Si:0.75 ~ 0.85%, Fe:0.2 ~ 0.5%; Cu:0.8 ~ 0.9%; Mn:0.05 ~ 0.08%; Mg:1.3 ~ 1.4%; Zn:0.02 ~ 0.05%; Ti :≤0.1%; V:0.13 ~ 0.2%; Surplus is Al and inevitable impurity.
Further, described aluminium alloy also comprises the Cr that weight percent is 0.1 ~ 0.15%.
Because technique scheme is used, the present invention compared with prior art has following advantages: high strength of the present invention low substance Al-alloy bicycle tubing, by introducing Zn and V in its cast material aluminium alloy, the active Zn element of one side adds can make bicycle tube form galvanic cell, thus avoid the corrosion of Fe element in aluminium alloy, improve work-ing life and the intensity of bicycle tube; On the other hand can form the V-Ti alloy body of infusibility with Ti adding of V element, thus be dispersed in aluminium alloy, effectively can improve its intensity and corrosion resistant ability.
Embodiment
