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:How to purchase PE polyester coated aluminum sheet and PVDF fluorocarbon coated aluminum coil?
Both belong to color coated aluminum sheet and coil. Customers can purchase ordinary aluminum sheet or coil, and then go to special coating company to add PE polyester coating or PVDF fluorocarbon coating. The color is bright and quality is also very good. PE polyester coated aluminum and PVDF fluorocarbon coated aluminum coil has a wide range of usages: construction industry (aluminum-plastic panel, aluminum honeycomb, roof corrugated sheet, fireproof veneer, aluminum ceiling, shutter, rolling shutter door, garage door, awning, water gutter), electronic appliances (computer chassis, computer panel), lighting, furniture, solar reflector, air conditioning duct and the like. At present it is still applied in many areas including electronic appliance, instrument, lighting, packaging and house decoration.
Q:Can aluminum foil be put in microwave oven?
Aluminum foil can be used in the microwave oven. Since chicken wing tip, chicken breast or fish head, fishtail or cake edges are easy to overcook, wrapping them with aluminum foil can be helpful to evenly cooking. Tips for microwave oven: 1. Use aluminum foil paper. Since chicken wing tip, chicken breast or fish head, fishtail or cake edges are easy to overcook, wrapping them with aluminum foil can be helpful to evenly cooking. 2. Use vessel cover or fresh-keeping film cover. When cooking or stewing food, to keep the original flavor, prevent evaporation and speed up cooking, vessel cover or fresh-keeping film cover are recommended to use. 3. Use tissue or napkin. Putting a tissue under the food such as baked bread, biscuit, chicken/pork pieces with bread crumbs can keep the food dry and crisp. Covering or wrapping the steamed bun or cakes with wet gauze or tissue can prevent evaporation. 4. Stirring the soup to reset the sliced meat, beefsteak and so on can help improve the cooking. 5. Lay the food aside or add seasoning after heating (for example, add emulsified oil or sauce and then sprinkle chili powder or bread crumbs )can achieve an effect that cooking does not achieve.
Q:How about the heat dissipation of aluminum tape?
Aluminum tape has good resistance to humidity, acid, chemical corrosion and ultraviolet ray as well as excellent thermal conductivity. The enhanced aluminum tape has a better toughness and strength.
Q:What are the functions of vacuum bag and aluminum foil bag?
Vacuum bag, also called close-fitting moisture-proof bag, aluminum foil bag, aluminum-plastic composite bag, adopts PET/AL/CPE or PET/NY/AL/CPE as its material. Among them, PET has good printing effect, NY low oxygen permeability, AL strong barrier property and light tightness and CPE double packing. Adhesive: Water-soluble adhesive (more sanitary, environmental with less liquid residue) is featured by good anti-staticness, oxygen isolation, shielding, moisture-proofness, opacity and heat sealability. The products can be reinforced with anti-static function, product description, company logo and anti-static marks with no changes of product performance according to the special requirements of users. It is suitable for electronics, communications, national defense in which vacuum packaging is required. Aluminum foil bag usually refers to aluminum-plastic composite vacuum bag, suitable for moisture-proof and light-proof vacuum packaging of large-scale precise machinery and equipment, chemical raw materials and pharmaceutical intermediates. With four-layer structure, it is characterized by good water-proofness and oxygen isolation. Aluminum foil bag can be made into flat pocket style, three-dimensional bags, organ bags, etc, according to the requirements of customers. The test results of GB and ASTM show that the product complies with environmental requirements (a third party testing report available if required) and the environmental standard of EU and North America in which packing material is most strictly required.
Q:how to find 0.6mm waste strake of aluminum sheet?
Heating wire is mainly used for electrical heating, has large power consumption. But aluminum sheet’s cooling fin mainly uses steam or hot water to conduct Thermal dissipation, it needs hot water or steam boiler. Comparatively, Heating wire conducts Thermal dissipation quicker, but cools quicker after power outage. Aluminum sheet is in the opposite condition.
Q:Why the wall insulation aluminum foil is put in the warm side
Putting in the warm side can save the energy and equal to the temperature preservation ratio: In winter,the temperature preservation aluminium is in the interior side of wall in the north.when the temperature of wall rises, the temperature of room is comfortable and the energy consumption is reducing. If putting in the exterior side of wall, the temperature in the room can be risen only after the wall temperature being rising, and the energy consumption is increasing.
Q:Is tin foil paper the same as aluminum foil?
The difference between aluminum foil and tin foil, which are mainly used to wrap cigarette, is their thickness and control of high temperature resistance! “Tin foil” and “aluminum foil” are produced respectively by metal tin and aluminum through calendaring. Aluminum foil paper mainly use offset printing, for example, the disposable meal box on the plane which is made from aluminum foil and can be heated in micro-oven, some fried food and aluminum foil for hairdressing like the so called tin foil perm. Besides, aluminum foil is applicable to many fields like packaging, printing, medicine, electronic, food, and building.
Q:which kind of enterprises are aluminium sheet circles used in?
user use cold squezz method to transform the aluminum sheet circle into various standard capacitor shell, aluminium collapsible tube shell, which are broadly used in electron industry, daily chemical industry, medicine, education and automobile products,electrical appliance, heat preservation, machine manufacturing, automobile,spaceflight,military industry,mould, construction, printing and other industries.
Q:Why 5052 turn black after annealing during the production of aluminum alloy?
The aluminum oxide in the surface has been oxidized by other chemical elements.
