Product Description:

Aluminium alloys with a wide range of properties are used in engineering structures. Alloy systems are classified by a number system (ANSI) or by names indicating their main alloying constituents (DIN and ISO).

The strength and durability of aluminium alloys vary widely, not only as a result of the components of the specific alloy, but also as a result of heat treatments and manufacturing processes. A lack of knowledge of these aspects has from time to time led to improperly designed structures and gained aluminium a bad reputation.

One important structural limitation of aluminium alloys is their fatigue strength. Unlike steels, aluminium alloys have no well-defined fatigue limit, meaning that fatigue failure eventually occurs, under even very small cyclic loadings. This implies that engineers must assess these loads and design for a fixed life rather than an infinite life.

Another important property of aluminium alloys is their sensitivity to heat. Workshop procedures involving heating are complicated by the fact that aluminium, unlike steel, melts without first glowing red. Forming operations where a blow torch is used therefore require some expertise, since no visual signs reveal how close the material is to melting. Aluminium alloys, like all structural alloys, also are subject to internal stresses following heating operations such as welding and casting. The problem with aluminium alloys in this regard is their low melting point, which make them more susceptible to distortions from thermally induced stress relief. Controlled stress relief can be done during manufacturing by heat-treating the parts in an oven, followed by gradual cooling—in effect annealing the stresses.

The low melting point of aluminium alloys has not precluded their use in rocketry; even for use in constructing combustion chambers where gases can reach 3500 K. The Agena upper stage engine used a regeneratively cooled aluminium design for some parts of the nozzle, including the thermally critical throat region.

Another alloy of some value is aluminium bronze (Cu-Al alloy).

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:Which kind of material does aluminum sheet(aluminum oxide) belong to?
Q:8mm which type of aluminum plate is suitable for bending?
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.
Q:General characteristics of pure aluminium plate of pure aluminium plate
I really want to know to call 1362889760 for your reference as follows: according to the content of different aluminum alloy elements can be divided into 8 series respectively 1***, 2***, 3***, 4***.5***.6***.7***.8*** according to the different processing technology can be divided into cold and hot rolling. They can be divided into thin plate and medium plate according to their thickness. GB/T3880-2006 standard specifies a thickness of 0.2 millimeters, called aluminum foil. More commonly used grades: pure aluminum plate, 1060 plate. Foil. Thick plate, tensile tube. Extruded tube. Type. Bar. Cold processing bar mainly for corrosion resistance in forming of high places, but not of high strength components, such as chemical equipment, marine equipment, railway tanker, conductive materials, instruments and materials, electrode etc.. 3003: plate, strip. Foil. Thick plate, tensile tube. Extruded tube. Type. Bar. Wire rod。 Cold bar, cold wire, rivet wire, forging, foil, heat sink material mainly used for processing requires good molding property, high corrosion resistance, good weldability or parts, or both have these properties need than the workpiece of 1*** alloy with high strength, such as the transport of fluids tank and tank, pressure tank, storage device, heat exchanger, chemical equipment, aircraft fuel tank, oil pipe, reflective panels, kitchen equipment, cylinder washing machine, rivet, wire. 3003 aluminum alloy sheet, plate, tube drawing. Extruded tubes, houses, partitions, roof covers, piping, etc. 3004 plates, thick plates, tensile tubes.
Q:what will happen when aluminum sheet is put into copper chloride solution?
the chemical equation of the reaction, 2Al+3CuCl2=2AlCl3+3Cu, the phenomena when aluminum sheet is put into copper chloride solution: there is red solid generating on the surface of aluminum sheet.
Q:I have a number of existing 4mm aluminum plate,
And the same direction in the rolling, more than 1.5 of the thickness of cracking is more serious; it is proposed to increase the bending angle of R, annealing may not be solved.Or on the bending line and calendering line to cross 45 degrees (comparison fee)
Q:What does 1060h/24 mean in aluminium alloy?
Each digit in the 1060-H24 stands for the following meanings:First, a number of Arabia 1 is representative of pure aluminum (aluminum is aluminum content above 99% aluminum, in addition to the beginning and start with 2-8 are 2### for copper and aluminum magnesium alloy, 3### aluminum manganese alloy, 4### alloy, 5### alloy and so on)Two, second, Arabia number 0, said the original alloy, such as 1, said the original alloy after a modification, 2 means that the original alloy after two modificationsThree, third and four 60 two Arabia data represent the value behind pure aluminum content of 99% per cent in pure aluminum, said 60 pure aluminum aluminum content of 99.60%, as the standard 1050 indicates the aluminum content of pure aluminum, 99.50% of the 1070 said that the aluminum content of 99.70% pure aluminum alloy in the back.
Q:How to prevent corrosion of aluminum sheet surface?
Directly on the surface coating H2SO4Because the AL and H2SO4 react to produce a dense oxide film that prevents corrosion again, the barrel containing sulfuric acid can be made from AL
Q:What the glue of L solidified aluminum and fast acrylic plate, solid glue?
Aluminum and acrylic adhesive, if you want to achieve high strength without any effect, can be bonded with KD-5603 trace glue, but this should be with the help of UV curing light curing, if there is no UV curing light, the sun is strong weather, stick in the sun after 30 minutes can be the bonding effect of glass panel; the specific effects can refer to the general glass coffee table with four Aluminum Alloy column, don't see any traces of adhesive;If you only need sticky sticks and low marks, you can choose N-906AB glue or KD-855 quick drying metal glue
Q:What is the density of the 1100 aluminum plate?
1100 aluminum density is fand 2.7g/cm.1100 for industrial pure aluminum, aluminum content (mass fraction) of 99%, can not be enhanced by heat treatment. With high corrosion resistance, electrical conductivity and thermal conductivity, and its small density, good plasticity, through pressure processing can produce all kinds of aluminum, but the strength is low.
