It is simply to divide aluminum and aluminum alloys into two categories: wrought aluminium alloys and cast aluminum alloys. Wrought aluminium alloys contain lower percentage of elements, about less than 4%. Cast aluminum alloys contain the same chemical composition but has greater amounts. In the same temperature range( 520 to 590℃), the cast aluminum alloys undergo a thoroughly chemical properties while wrought aluminum alloys still remain the mechanical properties and remain ductile.
As a result of the packaged goods and the outside light, moisture, gas and other sufficient isolation, so that the packaging is well protected. Especially for the packaging of cooking food, the use of this compound aluminum foil material, at least one year can ensure that food does not deteriorate. In addition, heating and unpacking are very convenient and popular among consumers. Generally, the thickness of aluminum foil is between 0.03mm and 0.1mm.
How to identify the quality of aluminum alloy plate
Is there an easy (cheap) way to identify aluminium alloys
Usually judge alloy aluminum plate quality time must pay attention to the appearance of brightness, survey bat bao hou is even even, pinch the board with the hand, feeling the elasticity and patience isn’t is good. Its main function is to make the moisture in the hot air on the heat exchange sheet coagulate into water droplets easily spread and flow down the sheet.
Aluminum foil is a pretty cool kitchen tool. It can be molded to any shape and can
completely block moisture and air if you fold the edges properly. And you can use it more than once. That’s right — more than once!
One of my least favorite chores of all time is cleaning residue off my cookie sheets. We’ve all been there, you forget to spray the pan with oil before placing it in the oven and before you know it, you have a hardened mess on your hands. In order to make my life easier and avoid mistakes such as this, I’ve learned to line my sheets with aluminum foil. However, doing this leaves me with an abundant amount of used aluminum foil that I hate throwing away. To help minimize the waste, I’ve come across the options below for reusing used foil!
Aluminum foil flexible pipes can deliver all kinds of media of temperatures between -50℃ and 150℃. They are applied in heat or cold maintaining projects for centralized heating, central cooling and hot oil delivery in industries like petroleum, chemical, coal, refrigeration and heating supply. Although you may have caught sight of the pipes a lot in daily life, you might not pay enough attention to their structures.
aluminum foil is ductile. Foil can be rolled to only 0.007 mm thickness, but will still be completely impermeable and lets neither light, aroma nor taste substances in or out. The metal itself forms a protective oxide coating and is highly corrosion resistant. Different types of surface treatment can further improve these properties
Aluminum is a pretty good conductor. For a while it was competing with copper for wiring in home construction though safety concerns arose. Concerning aluminum foil, its thinness is an issue since the cross section of a conductor impacts electrical resistance. If you take a thin strip of Al foil and attach a dry cell battery, you will find it rapidly heats and then combusts.
The soft pack battery is made of 8021 alloy aluminum foil 0.04mm thickness, and there are other aluminum foils (1235/1060/1070 pure aluminum 0.012-0.016mm thickness). The product is widely used in electric bicycles, electric vehicles, power tools, electric toys, solar photo voltaic power generation systems, cigarette lighter power supplies, emergency lighting, portable power sources and mine safety equipment
The main difference between them is that the melting point of aluminum foil is higher than that of tin foil paper and is more suitable for barbecue food.
