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).

Aluminium foil acts as a total barrier to light and oxygen (which cause fats to oxidise or become rancid), odours and flavours, moistness, and germs, it is used broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic processing|aseptic packaging) for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods.

Aluminium foil is widely sold into the consumer market, often in rolls of 500 mm (20 in) width and several metres in length.It is used for wrapping food in order to preserve it, for example, when storing leftover food in a refrigerator (where it serves the additional purpose of preventing odour exchange), when taking sandwiches on a journey, or when selling some kinds of take-away or fast food. Tex-Mex restaurants in the United States, for example, typically provide take-away burritos wrapped in aluminium foil.

Aluminium foils thicker than 25 μm (1 mil) are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the production process.

Q:help with aluminium and titanium questions?
1. When exposed to air, pure aluminium rapidly forms a passive oxide layer, alumina, which further inhibits aluminium reactions with other elements. 2. Aluminium can be made stronger by alloying with other elements. One of the most known aluminum alloy is duraluminium, where the principal alloying component is copper. 3. Exactly as aluminium, titanium corrosion resistance is due to its high reactivity with oxygen. When pure titanium is exposed to air it forms a passive titanium dioxide layer on the surfaces exposed which further prohibits other reactions with corrosion agents. 4. The use of titanium in jet engines components is favored by its strength to weight ration, which is unmatched by any other metal. As for the nuclear reactors, its use is preferred because of its superior corrosion resistance associated with fracture toughness and overall durability. 5. Both titanium and aluminium are refined from their respective mined ores - bauxite, for aluminium, ilmenite and rutile for titanium. Basically, these are oxides of the metals. Pure metal has to be reduced from these ores and processes involve use of temperatures up to and sometime exceeding 1000 degrees Celsius, which obviously requires a great consumption of energy, including electricity. Moreover, pure aluminium is obtained in the final processing phase through electrolysis, meaning an electrical current is needed in order to drive the required chemical reactions, thus adding to the electrical consumption. 6. Recycling aluminium from aluminium simply requires the remelting of the metal, eliminating the electrolytic phase that is high electric energy consuming.
Q:Spacing of stiffener
As to the stiffener of the aluminum veneer, what are the following points?:1, aluminum reinforcement spacing is generally around 600mm, in order to ensure the aluminum plate in the positive and negative pressure conditions within the scope of deformation. When aluminum plate is welded, there is internal stress due to welding deformation (this internal stress can not be completely eliminated for a long time), and the rigidity of reinforcing bar should also be increased.2. The sectional dimension and spacing of stiffeners shall be determined according to the calculated wind pressure of the aluminum plate. But it is worth noting that the reinforcement calculation of single aluminum plate strengthening is different from the glass curtain wall, first, its strength is certainly no problem (still not seen the wind blowing broken plate, there is no joke) deflection possibility, bend off and windy weather also very few people to pay attention to the single aluminum plate plate surface after deformation the scenery. Therefore, the calculation of deflection of stiffeners are considered under the condition of wind strength and deflection when the winds of aluminum can cause permanent plastic deformation.In fact, aluminum veneer manufacturers generally use the single aluminum plate edge folding groove made of aluminum and 20*40*20, installed in the distance about 600mm. Also useful for profile (grooved aluminum) stiffenersThe spacing between stiffeners is very important to the cost of production. Generally speaking, the spacing of stiffeners will be changed from 600 to 350, and the cost will be increased by 8~15 yuan / square meter
Q:on the metal activity series, aluminum sits between magnesium and zinc, and all three sit above hydrogen.?
Aluminum metal reacts with oxygen in the air to form a very tightly bonded aluminum oxide on its surface which slows the attack of acids trying to make contact with the aluminum atoms below the surface.
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:Aluminium or hi-ten bike?
hi ten is always cheap heavy junk on the other hand aluminum can be pretty crappy too if it costs under $300 don;t expect miracles either way but i would still say aluminum wle
Q:Excuse me: what kind of aluminum sheet is the cheapest? Which materials are more expensive?
Among them, 3003 for aluminum manganese alloy, the lowest price in the 3 series, and then 3004.3104, for aluminum, magnesium, manganese alloy than 3003 price to be slightly higherThird bit, 5 series, i.e. aluminum magnesium alloy, such as 5005.50525083. 5005 of these prices are slightly lowerThen, the ---2 system and --4 system and --7 system of the 6 series are derived
Q:Which kind of solution should I use while welding aluminum sheet and copper pipe by tin soldering?
1, you must use over 350W soldering iron, 2,prepare some borax and tin soldering paster, you can’t use rosin to weld it, 3, polish the pipe to clean with fine abrasive paper and borax, 4, put the pipe and sheet into borax, use the soldering trip to rub on the weldment with some borax. 5, after the pipe and sheet become hot, use the soldering iron with the paster and tin to rub the pipe and sheet in borax, then it can be welded. 6, they can be welded together after welding.
Q:question about drilling aluminum?
Aluminum is softer than steel, so you could just use the ordinary bits that you use for wood, with a hand drill. For cleaner holes, you might want to put wood behind the aluminum as a backing. Also, if you squirt a drop of oil onto the drill area, that will help. If you're trying to drill a really large hole, it might be better to drill small ones, and enlarge with a round file.
Q:Toxic Effects of Aluminum in Antacid?
Q:What are the causes of aluminum plate quenching cracking?
If the material is right may be burned, a full air bubble is parts of the surface, whether the intergranular cracking section, part to do see the metallographic analysis of grain size, lower furnace installed furnace capacity amount control too much away from the direction of the thermocouple parts temperature indicator indicates the temperature to the temperature time lag of thermocouple thermocouple has high temperature parts away from the direction. 510 is enough to regularly test the stove uniformity and precision with 2 kinds of stove fan check
