Product Description

 

Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates.

Despite its prevalence in the environment, no known form of life uses aluminium salts metabolically. In keeping with its pervasiveness, aluminium is well tolerated by plants and animals. Owing to their prevalence, potential beneficial (or otherwise) biological roles of aluminium compounds are of continuing interest.

The earliest citation given in the Oxford English Dictionary for any word used as a name for this element is alumium, which British chemist and inventor Humphry Davy employed in 1808 for the metal he was trying to isolate electrolytically from the mineral alumina. The citation is from the journal Philosophical Transactions of the Royal Society of London: "Had I been so fortunate as to have obtained more certain evidences on this subject, and to have procured the metallic substances I was in search of, I should have proposed for them the names of silicium, alumium, zirconium, and glucium."

Q:What are cold rolled aluminum coils and hot rolled aluminium coils, what are their respective features?
The difference between hot rolling and cold rolling is that cold rolling is rolled at recrystallization temperature and hot rolling is above the recrystallization temperature.
Q:What are the differences between aluminum coil 3003h24 and 3a21h14?
The mechanical property references of rolled plate 3003 H24and 3A21 H14 are as follows: 3003 H24--Rm/MPa≧140-180;Rp0.2/MPa≧115;A(%)≧1-5(thickness 0.2mm-4.5mm)3A12 H14--Rm/MPa≧145-215;A(%)≧6
Q:Can kerosene lubricate and cool aluminum coil when continuous punch?
Yes, because water and oil are not solute, but they will emulsificate.
Q:Why does the heat preservation aluminum roll bend when it is cooled?
Insulation aluminum coil will appear when the cooling bending phenomenon, reason is generally under the conditions of air cooling, the heat transfer coefficient of the aluminum coil insulation parts in contact with the air were flat, but because the wall thickness or different shapes, different parts of the heat dissipation rate is not balanced, resulting in thick wall or hollow tube heat faster than the thin Department of slow, resulting in insulating aluminum roll cooling occurs to the hollow part or thick walled parts of the twists and turns of the phenomenon.
Q:What does 1060 of the 1060 Aluminum rolls stand for?
At present, most of the circulation in the market is 1050 and 1060 series. 1000 series aluminium plate to determine the minimum aluminum content in this series according to the amount of the last two Arabia figures, such as the 1050 series of the last two Arabia number 50, according to the international brand naming principles, content must reach 99.5% to the top for qualified products. China's aluminum alloy technology standard (gB/T3880-2006) is also clearly defined, 1050 aluminum content of 99.5%., the same reason, 1060 series aluminum plate aluminum content must reach more than 99.6%.
Q:How much is one square aluminum gate and five hard door?
Double layer aluminum alloy, in the middle of the 5 bars, ordinary white or beige is 215, a square, the motor, in addition, the general 600KG copper core motor has 550 sets, there are 680 sets. On the Alibaba website search "roll gate", there are many manufacturers, you can ask them.
Q:What does it mean to slice aluminum coil by decoiler machine?
The operating procedures of decoiler machine: 1, Select appropriate aluminum coil according to production work order requirement to be processed, paying attention to the thickness, width and material of aluminum coil. 2, Put the aluminum coil into the coil loading car with traveling crane and inch the car into the uncoiler. The aluminum coil and decoiler machine should be in the same direction. Hold the aluminum coil down with leading head, and open the auxiliary bearing. 3, Turn on the shovel head, and inch the uncoiler to lead the aluminum sheet into the leveler. Adjust the leveler according to the thickness and width of aluminum sheet to ensure the flatness. 4, Turn on the front gap bridge and back gap bridge in control main platform, inch the leveler to lead aluminum sheet into re-leveler. Adjust the re-leveler to ensure the flatness of aluminum sheet. Put it into the shear gauge and plate shearer. 5, Take back the front and back gap bridge. Inch the plate shearer to cut off the sheet head and shear the aluminum sheet according to production work order. Check the first sheet to see whether it meets the quality standard and whether there is defect in flatness, length, diagonal, and surface of aluminum sheet. If it is qualified, turn on the conveyor. Put the aluminum sheet holder on the pallet. Adjust the pallet according to the width and length of aluminum sheet. Input quantity and length on the control main platform. Then turn on the auto control to produce automatically. The production process can be observed at any time. 6, If there is aluminum coil left, unwind, package and put it into storage in reverse steps.
Q:The general roll also 5,6t appearance, specific to your own weigh, length, weight = / (width * thickness * density)
Oh, landlord, this question is a little interestingIf it is the embryo of the aluminum plant, the aluminum roll is usually 5-6 tons a rollFor a while, in the merchant or the direct manufacturer, it is necessary to see how large the material rack is in the factory. It is usually 1.5-2 tons, and there are also three tons.Yes, please!
Q:What are the main causes of aluminum strip rolling?
Different thickness analysis is not the same, is curly after the thickness of the upper rib, or out of the roll can be visual?
Q:Why the end of the aluminum coil will have a yellow spot?
The reason may be that the manufacturer is not cleaned, and must be carefully cleaned before coating, or there may be paint fall off phenomenon.
