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:Foil type: 3003 and 8011, how can distinguish between the more detailed the better?
If the state is H243003 less than 8011 elongation of aluminum foil, but 3003 high tensile strength. Some foreign products with more than 3003 brands of aluminum foil.
Q:Heat of Aluminum?
The specific heat of pure aluminum is 0.23 BTU/lbm- deg F. That is also equal to 0.23 cal/g-deg C So lets see how close this is. 1100 calories/(60g * 70 deg C) 1100cal/4200 g - deg C = 0.262 cal/ g - deg C I believe that to be right
Q:How to wash away the oil of aluminum foil products after being pressed?
I suggest that you can use the volatile punching oil since it won't be rudimental.
Q:What are some Physical and chemical properties of aluminum??
N Is not poisonous. P Less dense than other materials. P Ductile. P Silvery-gray color. P Used to form lightweight alloys C Useful as a container for food products. C Good conductor of heat and electricity. C Does not corrode. P Malleable.
Q:can aluminium 2x4's be used outdoors?
I think it will work fine. Be sure it's aluminium and not sheet metal.
Q:What's the difference between the cold rolling and hot rolling.
The aluminum foil has no hot rolling and the original billet isn't cold rolling.
Q:Is aluminium foil ultraviolet-proof?
Yes
Q:Aluminum 14' boat weight?
i once asked that same question about my 16' aluminum hull. i was able to supply some crucial details, year, make and model. but the best answer i got was roughly 1,000 lbs. my 16' aluminum boat has a 248 lb 60 hp outboard on it. hitch weight ranges from lift enough to curl with one finger to the weight of gear and batteries in the bow. my dad's 04 honda accord (4 banger w/ automatic) has no trouble at all pulling it to the local lakes, within 15 miles, and up the SMALL hills on the way to them. but i wouldnt dream of a long trip or major mountain ranges with it. thats what my chevy truck is for. its tranny is made for the load and wont overheat. as a guess, your total weight is 1,200 empty for the boat, trailer and outboard and 1,500 with gear. for a real answer, perhaps you can get an accurate one if you provide crucial details. or you can find somewhere with scales you can use. trucking companies, rockeries (where you get big rocks or lots of dirt for landscaping needs), major recylcers, lots of places do have scales you could probably use. you'll need to either disconnect the trailer and leave it with all tis weight on the scales or disconnect it fromt eh tow vehicle and weight the tow vehicle seperately.
Q:How does aluminum foil bag should be heat-sealed?
If you don't vacuumize bags,heat-sealing machine is ok. Some heat-sealing machines have hand grips, some are pedaled or with belt wheels. Prices vary with different manufacturers. If you want to vacuumize bags, a vacuum machine is ok. After the vacuumizing process, the vacuum machine is directly sealed.
Q:What's the highest temperature the aluminum foil and tin foil can resist?
Tin foil paper can resist high temperature. Aluminum foil paper or aluminum foil which is also called tin foil paper in Hong Kong, is a kind of thin sheet of less than 0.2mm in thickness processed by aluminum foil roller. It is mainly used to cook and contain food, or make some kinds of material for cleaning. Tens of and thousands of aluminum foil papers are used to preserve and package food, cosmetic products and chemical products. The applications of tin foil paper are as follows: 1. Prevent food from sticking baking tray; 2. Prevent food from sticking dirty stuff; 3. Convenient to clean baking tray; 4. Package the seasoning and stuffing to prevent them from falling into pieces when baking food; 5. Preserve water and keeping fresh.
