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.China Longbird Group is mainly engaging in coated aluminium coil, new construction material, education, automobile trade, machinery, general merchandise, real estate, investment, trade etc. The parent company is specialized in aluminium foil coating, which is the main material for the aluminium plastic composite panel. The aluminium plastic composite panel is a new kind composite panel based on coated aluminium coil panel and plastic panel. It centralize the merits of metal, dope and plastic, be characterized by excellent formability, heat insulation, weatherability, impact resistant, high intensity. For it’s excellent character and decorative effect, aluminium plastic plates be widely used on the great building, symbol structure and also the high-class abiding place. In Europe, it’s already the best choice for decorating building.

Q:Find a weld and riveting machine to connect the two roll of aluminum together. the width of aluminum is 40-60cm,because the surface of aluminum has a layer of oxidation film,so...
I am a high voltage professional welder. I can't endure the current surge,even the spot welding. the surface oxidation film can be baked by the cutting knife,or polish by the abrader. no matter how big the welding rod is useless.The aluminum is too thin.
Q:Is waterproof aluminum tape expensive?
5cm waterproof aluminum tape, high-temperature resistant, waterproof, thick to prevent being torn and radiation resistant, 6 yuan. 5cm waterproof aluminum tape, high-temperature resistant, waterproof, thick to prevent being torn and radiation resistant, 5 yuan. 5cm waterproof aluminum tape, high-temperature resistant, waterproof, thick to prevent being torn and radiation resistant, 2 yuan.
Q:How to produce aluminized paper?
Q:What temperature needed to keep the aluminium foil spray lacquer having the adhesive force
To judge the adhesive force of oil paint of aluminium paper,we should heat the double paint formulations and the curing agent of the lacquer to 80 degree and 150 degree.
Q:Is aluminum foil a kind of alloy or something else?
Aluminum foil is pure aluminum, (except for the fake) which is a kind of thermoprinting material made by calendaring aluminum into sheet. Since its thermoprinting effect is similar to that of silver foil, it is also called fake silver foil. As aluminum is soft and ductile with silvery luster, aluminum foil sheet can be made by mounting calendered aluminum sheet on the offset paper with sodium silicate, which can be used to print. But the color of aluminum foil will gradually become dark as it is easy to be oxidized and it fade due to friction and touching, so it is not applicable to the thermoprint of book covers for permanent preservation.
Q:Is aluminum foil insulation materials easy aging?
The use of aluminum and high surface reflection characteristics of multilayer aluminum surface reflection can be achieved completely block heat radiation purpose. But through the aluminum surface between the air and the like are still A small amount of convective heat transfer. If you require complete insulation, available multilayer vacuum aluminum reflective insulation structure.
Q:How aluminum foil is uesd in pharmaceutical packaging?
Another important market is the aluminum foil is easy to tear film (SP) production, currently there are more than 10 pieces of such production lines, aluminum demand is 3,000 tons / year. In addition salve packaging plastic composite hose, a liquid, injection two potential market cap is plastic composite packaging consumption of aluminum foil, aluminum foil current total demand of more than 1,000 tons.
Q:What's the important characteristic and the advantages of aluminum food package bag
The aluminum food package has the advantages of withstanding high temperature,puncture-resistant,deformation.The package materials of aluminum are made of PE/AL/PE/CPP. The PE is effective in painting.
Q:The applications of aluminum foil
Scrap aluminum foil can be used to make poly aluminum chloride which is a common kind of inorganic polymer flocculants. The broad sources of raw material for manufacturing poly aluminum chloride lay the foundation for its development, especially the diversity of production processes which provides convenience for the development of poly aluminum chloride. International and domestic manufacture and application has scaled up and theory research has gained further development. Manufacturing material mainly include bauxite, aluminum hydroxide and waste molecular sieve catalyst. Manufacturing methods mainly contain wet process and electrolytic process. As some scholars think scrap aluminum foil has high economic value for recycling, they research the best conditions to produce poly aluminum chloride with scrap aluminum foil and the range of application for purifying water via experiments. With the development of industry and the rapid growth of urban population, water pollution is increasingly serious, which lead to more sewage to purify and more purifier to meet the increasing demand. As poly aluminum chloride molecule has different quantities of hydroxyl, it will hydrolyze under the PH condition of the source water and be accompanied with a series of physical and chemical process like coagulation, absorption and deposit after adding poly aluminum chloride to the turbid source water to purify the water. There is a wide source for scrap aluminum foil mainly from the package of cigarette, food and medicine, whose main component is aluminum, so it has high economic and social value to recycle scrap aluminum foil. The best conditions to produce poly aluminum chloride with scrap aluminum foil and the range of application for purifying water have practical significance for the increase of resource utilization rate and environment protection after test and research.
Q:Can you tell me how to use aluminum foil grill ?
Aluminum foil tray can be directly put into oven instead of using grill. If you buy grill for yourself, always buy a smaller one in case the size is not right. Like the Korean BBQ store, put the tray onto the grill and brush a little oil after heating. What you do next is turn them over and over again.
