Preparation method's step of this aluminum alloy plate materials is: select commercial-purity aluminium 1080 to place cast-iron pot as raw material, be heated to 730～750 ℃ of fusings with the 5kW resistance furnace, add again magnesium ingot, rotate refinery by de-gassing 15min with high-purity argon gas after leaving standstill 10min, the complete rear temperature adjustment to 720 of degasification ℃ is also left standstill 30min and is pulled out slag again, again furnace temperature is down to 660-680 ℃, begins to be cast in and be preheated in advance in the 200-220 ℃ of mould, then room temperature cooling.
Describe the preferred embodiments of the present invention in detail below in conjunction with accompanying drawing.
Embodiment 1
A kind of new A l-Mg alloy, each element proportion is in this Al-Mg alloy: Mg:0.8%; Si:0.14%; Fe:0.14%; Cu:0.03%; Mn:0.02%; Zn:0.02%; Ti:0.02%; Al: surplus.
The technique effect of this embodiment 1 is as follows:
1, after this novel aluminium process polishing, the oxidation, surface brightness is suitable with fine aluminium material luminance brightness, and because its higher Brinell hardness, tensile strength and yield strength etc., can be widely used in the inside and outside gadget of automobile, not only keep good brightness effect, can also guarantee the work-ing life of gadget.
2, this novel aluminum product has again preferably tensile strength, yield strength and hardness simultaneously, and its physical strength and 5 is that aluminium sheet is similar.Fig. 1-Fig. 3 is fine aluminium, Al-Mg alloy, 5052 H32(Mg:2.2～2.8) each mechanical property graphic representation of aluminium sheet (observed value all is to record at ambient temperature, and aluminium plate thickness is 1mm), among the figure, (a) represent pure aluminum plate; (b) represent the Al-Mg alloy sheets; (c) represent 5052 aluminium sheets.The tensile strength of fine aluminium, AL-Mg alloy, 5052 aluminium sheets is respectively about 70MPa, 150MPa, 195MPa as seen from Figure 1.So along with the increase of other elements such as Mg, the tensile strength of aluminium sheet increases gradually.The yield strength of fine aluminium, AL-Mg alloy, 5052 aluminium sheets is respectively as seen from Figure 2: 30MPa, 110MPa, 90MPa, and wherein the yield strength of Al-Mg alloy is maximum; The Brinell hardness of fine aluminium, Al-Mg alloy, 5052 aluminium sheets is respectively as seen from Figure 3: 19N/mm2,40N/mm2,47N/mm2, so along with the increase of other elements such as Mg, the aluminium sheet Brinell hardness increases gradually.
