The communication that the present invention relates to is fabulous with the workability of aluminium alloy, adds the chip volume can not take place man-hour stick up or damage problem such as machining tool, can shorten the process-cycle.Simultaneously, can significantly reduce the fraction defective of converted products, improve the converted products quality, and reduce the residual amount of burr (burr), be convenient to the removing and the cleaning of burr (burr).Therefore, the communication that the present invention relates to can significantly promote production efficiency with aluminium alloy adding man-hour, has remarkable cost-effective effect.
Description of drawings
In order to understand essence of the present invention and feature better, be elaborated below with reference to the accompanying drawings, wherein:
Fig. 1 is that the aluminium alloy test piece of producing in embodiment 1 and the reference examples 1～3 is in the situation that adds the chip in man-hour
[(a) reference examples 1, and (b) reference examples 2, and (c) reference examples 3, and (d) embodiment 1].
Embodiment
The present invention relates to 1.2～1.4 weight % of Si in the aluminium alloy gross weight, Mg 0.6～0.75 weight %, Sn0.8～1.0 weight % and all the other is that Al and impurity are the Al-Si-Mg line aluminium alloy and the production technique thereof of characteristics.
The aluminium alloy that the present invention relates to has added low melting point metal Sn to be the processing characteristics of communication aluminium in order to improve 6000, and for material property after preventing to add above-mentioned Sn reduces and the raising rerum natura, optimization Si and Mg content are characteristics.
" impurity " that the present invention relates to is meant the unexpected composition that takes place in the alloy production process.
In the aluminium alloy gross weight that the present invention relates to, the desired contents of Si is 1.2～1.4 weight %.When containing quantity not sufficient 1.2 weight %, can cause alloy rigidity to reduce, surpassing 1.4 weight % then can reduce because of high alloy causes casting speed at the making continuously cast bloom period of the day from 11 p.m. to 1 a.m, thereby reduction production efficiency, and, reduce extrusion speed and surface quality along with the increase of when extruding material stress of fluidity.Simultaneously, influenced by over-drastic Excess-Si, the problem that hardness value rises and causes the tool wear amount to increase can take place.
In the aluminium alloy gross weight that the present invention relates to, the desired contents of Mg is 0.6～0.75 weight %.When containing quantity not sufficient 0.6 weight %, the sticking possibility of the burning of processing chip is higher, and generates Sn and throw out, causes playing the Mg of enhanced physical properties effect
2The Si contents of precipitate reduces relatively, thereby reduces the rerum natura of material; When surpassing 0.75 weight %, basilar fibers shape tissue can be reinforced, and makes the length of processing chip elongated, thereby reduces its workability.
In the aluminium alloy ingredient that the present invention relates to, Sn can generate Mg and Mg-Sn is a throw out, and this throw out can play the effect that destroys chip in the course of processing, thereby improves workability, and this specific character can along with Sn content what too or not enough.When Sn less than 0.8 weight %, the improvement of workability has little effect; When surpassing 1.0 weight %,, strengthened because the burning between the processing chip is sticking and added the impaired possibility of instrument in man-hour though the size of processing chip can diminish.
In the aluminium alloy gross weight that the present invention relates to, the desired contents of Mn is 0.50～0.70 weight %.Mn can suppress compound formation needle-like such as AlFeSi, and to improving the required crystalline particle granular effective elements of intensity.When Mn less than 0.50 weight %, the acicular possibility of compound formation such as AlFeSi is higher, and the crystal grain granular has little effect; When surpassing 0.70 weight %, the problem that intensity reduces can take place on the contrary.
Simultaneously, in the aluminium alloy gross weight that the present invention relates to, can be added on the mentioned component of selecting among the group who forms by Fe 0.001～0.50 weight %, Cu 0.01～0.10 weight %, Cr 0.01～0.25 weight % and Zn 0.01～0.20 weight % more than a kind.When surpassing mentioned component content, the generation of intermetallic compound may cause its rerum natura to reduce, and weakens extruding, from becoming the reason that reduces production efficiency.
In addition, also can relate to other Composition Control outside the composition below 0.15 weight % with above-mentioned.The aluminium alloy that the present invention relates to is for suppressing the generation of other intermetallic compounds, and suggestion is pressed foregoing and regulated content of elements.
In addition, the present invention relates to:
Si 1.2～1.4 weight %, Mg 0.6～0.75 weight %, Sn 0.8～1.0 weight % in the constituent gross weight, and all the other are the preparatory stage of the Al-Si-Mg line aluminium alloy of Al and impurity with constituent;
Above-mentioned aluminium alloy is made into the stage of semifinished product by continuous casting process with constituent; And
The semifinished product that the above-mentioned stage is made homogenizes the heat treated stage of thermal treatment, extruding, stretching and timeliness,
Above-mentioned timeliness thermal treatment is to be processed as the production technique of the Al-Si-Mg line aluminium alloy of characteristics under 130～150 ℃ of environment.
In above-mentioned manufacturing process, except other technologies of Al-Si-Mg line aluminium alloy constituent and timeliness thermal treatment temp all can be utilized disclosed process implementing in this field.
Above-mentioned timeliness thermal treatment can rerum natura as required change thermal treatment temp, because of the characteristic on the above-mentioned composition, for example along with the interpolation of Sn, the precipitation situation of compound is not equal, therefore different with common method, 130～150 ℃ processing environment is adopted in suggestion, it would be desirable under 140 ℃ of environment and carries out heat treatment step, and this is to the precipitate distribution that realizes homogeneous and to prevent that thick throw out from generating very effective.
In above-mentioned production technique, in the aluminium alloy gross weight, Mn0.50～0.70 weight % is added in suggestion to aluminium alloy again with constituent.In addition, the aluminium alloy that the present invention relates to can be added on the mentioned component of selecting among the group who is made up of Fe0.001 in the aluminium alloy gross weight～0.50 weight %, Cu 0.01～0.10 weight %, Cr 0.01～0.25 weight % and Zn 0.01～0.20 weight % more than a kind.
