Technical field
The present invention relates to a kind of preparation method of aluminum alloy materials, particularly relate to a kind of aluminum alloy materials that is used for the aluminium alloy extruded member of ultra-high voltage electric wire insulation support and preparation method thereof.
Background technology
As everyone knows, some aluminium alloy extruded member usually proposes the specific function requirement to the product mechanical property for the specific function purposes.For example be used for the insulation of ultra-high voltage electric wire and support aluminium alloy extruded member, its supply of material attitude product hardness need be controlled in the HB=50-70 scope.Conventional Al-Mg-Si alloy is because of its alloy element wide scope, and is difficult to satisfy this particular requirement by the reasons such as annealing effect that alloy element causes, and more can't form stable large-scale production ability.
Summary of the invention:
Main purpose of the present invention is to overcome above deficiency and a kind of processing method of introducing the alloy element selective control is provided, by alloy thermal treatment history to the dependence of this " selectivity " and be used for the insulation of ultra-high voltage electric wire support aluminium alloy extruded member and aluminum alloy materials and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is: it is characterized in that: the aluminum alloy materials of electric hardware fittings, form by the following ingredients weight percent,
Mg：0.48～0.52％；Si：0.26～0.28％；Fe≤0.15％；
Mn≤0.10％； Cu≤0.10％； Ti≤0.05％；
Zn≤0.05%; All the other are Al.
The preparation method of electric hardware fittings aluminum alloy materials, it comprises that aluminium alloy cast ingot homogenizing thermal treatment extruded section press quenching is handled and the artificial aging processing is characterized in that: the preparation method who is used for the electric hardware fittings aluminum alloy materials is as follows:
1.. meet mentioned component (weight percent) Mg:0.48～0.52%; Si:0.26～0.28%; Fe≤0.15%; Mn≤0.10%; Cu≤0.10%; Ti≤0.05%; Zn≤0.05%; All the other are the aluminium alloy extruded round ingot homogenization thermal treatment of Al: its homogenization temperature is 560-580 ℃, and soaking time is 6-8 hour;
2.. the homogenizing postcooling: begin to be cooled to 250 ℃ with high wind, 350 ℃/hour of its speed of cooling then, with being water-cooled to 50 ℃, are promptly come out of the stove again;
3.. Mg is carried out in heating before the ingot casting extruding
2The solution heat treatment of Si phase: Heating temperature is 500-520 ℃;
4.. extruded section directly carries out air-cooled or cold quenching squeezing out the nib place: quenching temperature should remain on 525-530 ℃;
5.. artificial aging: aging temp is 175 ± 5 ℃, and soaking time is 8-12 hour;
6.. extruded member finished product: its hardness value HB=50-70;
7.. check, packing, warehouse-in.
Advantage and positively effect that the present invention has are: the present invention introduces the alloy element selective control, on Al-Mg-Si alloy basis, provides a kind of controlled scope and solution treatment thereof, quenching and artificial aging processing method; Can obtain the stable and controlled supply of material attitude product of mechanical property scope, extruded member finished product hardness value HB=50-70, and batch produce and availability economically.
