Aluminum food and its alloy

Aluminum is a non-ferrous metal having a low density. The surface of the alloy is silvery-white, matte. It is very light and soft, due to which it has a low melting point - about 650 degrees. Its application found in all spheres of human life. It is actively used in the food industry, including for the manufacture of various dishes. In terms of production among all metals, it takes the second place in the world, after iron.

Aluminum is susceptible to aggressive acids. It is able to dissolve in concentrated alkali solutions. To avoid such phenomena, all aluminum products are covered with protective films. In crushed dusty state, being in an oxygen medium, it supports active burning.

A little bit about the properties and alloys of aluminum

The thermal conductive and electrically conductive properties of this metal are comparable with gold, silver and copper. It is very common in electrical engineering. It makes multicore wires and cables, create windings for electric motors and transformers. Aluminum is very plastic, but very fragile. It can be rolled up to the property of a translucent foil. Aluminum ingots can be easily cut and chopped. With the introduction of appropriate additives, the strength of the alloy can be significantly increased, thereby broadening the range of its application.

A similar alloy was developed in 1911 by German masters in the town of Duren. Hence the name of the alloy, consisting of aluminum, copper, magnesium and manganese - dural, or duralumin. Such a combination and a long hardening made it possible to increase the strength characteristics and maintain the same lightness (aluminum is 3 times lighter than steel). A great deal of duralumin alloy found in the aircraft industry, due to what was nicknamed "winged metal." To maintain anti-corrosion properties, it was coated with a spray of pure aluminum.

To exclude such a sputtering, another aluminum alloy with inclusions of silicon-silumin was developed. Due to its gloss and silvery color, aluminum is used in the manufacture of mirrors, both industrial and technical (for example, for telescopes), and household.

Use of aluminum alloys in the food industry

Aluminum in the food industry, as well as in everyday life, is used quite actively. From it, utensils, various containers for liquids and mixtures are made, machines and equipment for food production are made. For this purpose, food grade aluminum sheets are usually used. This is due to the fact that aluminum alloys do not affect the composition of products or components of cosmetics. All vitamins, nutrients, primordial properties and microelements are completely preserved. In addition, they are not capable of harming human health. Moreover, in the food industry only aluminum food and its alloys of certain grades are allowed to be used.

Metal alloys containing aluminum can also be used. All brands of this metal that are allowed to be used in the food industry must fully comply with GOST.

Use as a packing

In every house there were or even there are kitchen utensils made of aluminum - these are spoons, cups, pots, pans, juicers, meat grinders and much more. Very popular in the culinary world is aluminum foil, which is used for baking meat and vegetables or simply storing and transporting food. Such a foil is great for packing candies, chocolate, ice cream, butter, cheese and cottage cheese.

Many creams and cosmetics, artistic paint (oil, tempera, gouache and even watercolors) are packed in a container of alimentary aluminum. In them, food for astronauts is also packed. It can be said with certainty that aluminum, including food, and alloys based on it, have firmly entered our daily life.

Aluminum food is widely used in the production of canned food. Because of this spread, the amount of aluminum rubbish, without a case, decomposing in landfills, increases every year.

Advantages of food aluminum

Aluminum food has many advantages, among which one can distinguish the following:

1. Not exposed to corrosion. Thanks to this, kitchen equipment and tools are able to stay in the water for a long time without harm to themselves.
2. Food aluminum does not deform under the influence of high temperature.
3. Despite its coming into contact with materials possessing organoleptic properties, there is no change in the properties of the products. Also, all the vitamins they contain are stored.
4. Due to sufficient rigidity, the material during cooking is not deformed.
5. Food aluminum is absolutely harmless to the human body and completely hygienic.
6. Utensils from this material can be used for cooking in wind and microwave ovens.

Production of dishes and equipment for cooking from aluminum

Aluminum food and its alloys are part of many types of equipment for cooking. Since this metal is characterized by the ability to form all kinds of alloys, it, as mentioned above, is actively used to make a variety of kitchen containers. In addition, it is indispensable in the manufacture of all kinds of heat-resistant products. For example, equipment for kitchens and various fry surfaces of household appliances.

Aluminum differs excellent conductivity of heat at low heat capacity. In addition, it practically does not deform at high temperature or at its fluctuations. Due to the low melting point and its plasticity, aluminum is actively used for casting various products used in the kitchen. It is suitable for the manufacture of various surfaces that are characterized by deep relief, all kinds of complex shapes and products with a large area. For example, it is great for all kinds of forms for baking culinary products.

Aluminum alloys and GOST

Food aluminum, which is used for the production of dishes and other similar products, can be not only in pure form, but also in the form of all kinds of alloys, each of which has international and state quality standards, which indicate how and for what purposes they can be applied .

Food grade aluminum

Each brand of this metal has its own unique chemical composition. According to GOST, without taking into account the A5 brand in the food industry, it is possible to use such alloys as Ak5M2, AK7, AK9, AK12. All other brands of food aluminum are allowed to be used only with special permission.

Brands of metal alloys, including aluminum

It is also possible to use metal alloys in which there is aluminum. These include the brands AB, AVM, A0, AD1, AD1M, AL22, AL23, AMg22. All these alloys are actively used for making spoons.

Quite often, products made of aluminous aluminum or its alloys must be subsequently coated with a special coating. But this can be done with the AMC brand, as its chemical composition is fully consistent with GOST.

Aluminum food has long and firmly entered our everyday life. You can not find a kitchen in which there are no dishes made of this metal. Reviews about him are only positive, and, apparently, his popularity does not think to fall.
