Product Description:

1.Description

Aluminium atoms are arranged in a face-centered cubic (fcc) structure. Aluminium has a stacking-fault energy of approximately 200 mJ/m2.


Aluminium is a good thermal and electrical conductor, having 59% the conductivity of copper, both thermal and electrical, while having only 30% of copper's density. Aluminium is capable of being a superconductor, with a superconducting critical temperature of 1.2 Kelvin and a critical magnetic field of about 100 gauss (10 milliteslas).


2.Chemical

Corrosion resistance can be excellent due to a thin surface layer of aluminium oxide that forms when the metal is exposed to air, effectively preventing further oxidation.The strongest aluminium alloys are less corrosion resistant due to galvanic reactions with alloyed copper.This corrosion resistance is also often greatly reduced by aqueous salts, particularly in the presence of dissimilar metals.


In highly acidic solutions aluminium reacts with water to form hydrogen, and in highly alkaline ones to form aluminates— protective passivation under these conditions is negligible. Also, chlorides such as common sodium chloride are well-known sources of corrosion of aluminium and are among the chief reasons that household plumbing is never made from this metal.


However, owing to its resistance to corrosion generally, aluminium is one of the few metals that retain silvery reflectance in finely powdered form, making it an important component of silver-colored paints. Aluminium mirror finish has the highest reflectance of any metal in the 200–400 nm (UV) and the 3,000–10,000 nm (far IR) regions; in the 400–700 nm visible range it is slightly outperformed by tin and silver and in the 700–3000 (near IR) by silver, gold, and copper.

Q:What is aluminium plate L2-Y2?
China plastic deformation of pure aluminum grades are 1080, 1080A, 1070, 107000A (L1), 1370, 1060, 1050 (L2), 1050A (L3), 1A50 (LB2), 1350, 1145, 1035 (L4), 1A30 (L4-1), 1100 (L5-1), 1200 (L-5), 1235. Iron and silicon are their major impurities and are increasing by the number of brands.2, Y2: indicates that the material is in a semi hard state
Q:Aluminum knowledge. What is the model 3003 H24? What does H mean?
3003 is aluminium manganese alloy aluminum plate (Al--Mn), which is mainly composed of manganese.H24: continuous casting, continuous rolling, Zhang Liqiang and partial toughening.Is the aluminum plate with a thickness of more than 0.2mm to 500mm, 200mm width, length less than 16m aluminum material called aluminum plate or aluminum sheet, aluminum is below 0.2mm, 200mm within the width of the row material or bar (of course, with the progress of the large equipment, the width can be 600mm row material also more). Aluminum sheet refers to the rectangular plate made of aluminium ingot rolled and divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, middle thick aluminum plate and pattern aluminum plate.Aluminium alloy is added in the process of aluminum alloy elements (main alloying elements copper, silicon, magnesium, zinc, manganese, minor alloying elements such as nickel, iron, chromium, titanium, lithium, etc.) in order to improve the mechanical properties of aluminum and chemical index. Alloy aluminum sheet has some special properties of pure aluminum plate, and is widely used in special environment, such as ship, refrigerator, mould, aerospace equipment, etc..
Q:How to clean the aluminium oxide on the surface of aluminum? What kind of materials should we use to clean the thin aluminum sheet, and what's the concentration?
you can answer sodium hydroxide solution, dilute acid is useless, aluminum's oxide film is very thick,as for concentration, aluminum will be passivating in concentrated sulfuric acid. if you are high school student,higher concentration is better, you can complete deoxidation by abrasive paper.
Q:why is copper sheet but not aluminum sheet that becomes the negative pole after putting copper sheet and aluminum sheet connected with wire into concentrated nitric acid?
According to metal reactivity series order table, aluminum has a better metallicity, but it will be passivated soon after contacting concentrated sulfuric acid, and won’t react again. But copper and concentrated sulfuric acid can react continually. So aluminum sheet becomes the positive pole after passivation.
Q:6061 what is the density of the aluminum plate?
6061 aluminum plate density:6061 aluminum plate is aluminum alloy, the density is calculated according to 2.9g/cm3.Calculation method:Aluminium plate weight (kg) =0.0000029 * * * * width * lengthAluminium tube weight (kg) =0.0000029 * wall thickness * (outside diameter wall thickness) * lengthFormula for weight calculation of aluminium bars (kg) =0.0000029 * radius * radius * length
Q:What does aluminum plate mean?
Dear, 1070 and 1060 are not the specifications of aluminum sheet, but the type of aluminum plateThe model is used to distinguish the different components of aluminum, the model is different, the composition of aluminum is differentShenzhen Cheng Cheng metal - - - --- aluminum plate - -
Q:could aluminum sheet be attracted by magnet?
no, it couldn't.
Q:How do aluminium plates oxidize?
After anodizing, it turns white. If not, the aluminum plate should be white and spray polyester or fluorocarbon paint,
Q:What kind of aluminum sheet can be bent with five millimeters?
The aluminum plate can be bent five milimeter too much, if only bending words and aluminum quality has little relationship.First of all, the state is the most important, the state is divided into hard, semi hard, soft (usually soft called O state)The bending effect of the whole hard is not too far (the aluminum plate is H18, H19, H38 and so on are all hard)Semi hard aluminum sheets can basically be bent (H24, that is, semi hard)O bending is certainly not a problem, but because of too soft, basically with this state to bend lessSecond, you have to choose pure aluminum or alloy aluminum?Pure aluminum hardness is not very good, with 1100, 1050, 1060 and so on can be recommended 1100 H26Alloy aluminum hardness is better, can use 3003, 3005, 5052 and other semi hard state can be.Specific recommendations were then determined by 6061, 2024, 7075 if the hardness is too high, especially for the T6 state is more, should not bend, unless you're heating and folding the difference between aluminum and aluminum is poor oxidation resistance, tolerance, surface effect, crystal accuracy and the uniform stability of a difference, not only the bending effect difference.If the aluminum surface paint it quality do not too good, good is a waste, it is recommended to use 3003-H26, 3005H24 or 5052H34, the price of twenty pieces of it, made up to more than forty yuan per kilogram
Q:What are the causes of aluminum plate quenching cracking?
1. Crack type: longitudinal crackFeatures: by table and depthShape conditions: hardenability of the workpiece, easy to produce raw materials, carbide band segregation or non-metallic inclusions extensionPreventive measures: control raw material quality, select preheating treatment, improve original organization2. Crack type: net crackFeatures: located on the surface of the workpiece, depth 0.01 ~ 2mmSurface conditions: surface decarburization, heat treatment, surface hardening, easy to presentPrevent measures: take heating protection, avoid decarburization, delay quenching cooling, reduce quenching temperature3. Crack type: arc crackFeatures: located at the corner of the workpiece, hidden in the surface layerShape conditions: prone to Weicui through the workpiece or carburized partsPreventive measures: change workpiece design, cross section fillet rationalization4, crack type: peel crackCharacteristic: showing the delamination of hardened layerShape condition: surface hardening parts or heat treatment partsPrevention measures: reasonable choice of medium, delay cooling5. Crack type: microcrackFeatures: defects in microstructureShape conditions: hardening of high carbon martensite nearPreventive measures: avoid heating, hot, coarse grain
