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:What’s the production standard of aluminum coil?
GB/T3880-2006 mechanical standard GB/T3190-1996 chemical standard
Q:How much fluorocarbon and polyester paint should be used in production of aluminum coil and aluminum-plastic panel?
In theory, one kilogram paint can spray 6 square kilometers for your required thickness. Then you can calculate the total areas.
Q:What are cold rolling aluminum coil and hot rolling aluminum coil? What are their features?
If the rolling temperature is above the crystallization one, it is hot rolling, otherwise it is cold rolling.
Q:How to calculate the length of aluminum sheet with the thickness known?
Thickness*width*length=weight/density, length=weight/(density*thickness*width). Ps: Keep unit the same.
Q:Is aluminum veneer the same as color coated aluminum coil?
Aluminum veneer is processed aluminum sheet, while color coated aluminum coil is raw material with color which can be called aluminum veneer after process.
Q:How does aluminum ingot be processed to aluminum coil (aluminum sheet)?
First it should be made into blank and then put on the rolling mill.
Q:Will the surface of aluminum contact water if the aluminum coil falls into water?
Q:How to calculate the wall thickness with the gross weight of aluminum coil known?
Gross weight*density=volume volume÷(aluminum sheet *width)=thickness
Q:How much is the rust-proof and thermal insulation aluminum coil?
3003 alumal alloy is the best and common rust-proof and thermal insulation aluminum coil. The price depends on the thickness and width you need.
Q:How to measure the thickness of aluminum coil at real time? In what areas can the sensor be used?
Displacement sensor can be used in many areas, such as industry.
