Alloys are widespread today, and they can easily be met in any sphere. But nevertheless alloys with lead and aluminum enjoy the most bigger popularity. The concept "alloy" is meant as material which contains metals and other substances.
Often steadier metals become additional components to soft and plastic aluminum, but also it can be nonmetallic components: pine forest, sulfur and coal.
Alloys with aluminum content
One of the known alloys where it is possible to meet aluminum – aluminum connection with copper. The received metal has a simple formula and strong links thanks to what alloy can be applied in military and rocketry and also in spaceships. Use as a part of copper promotes improvement of indicators on resistance to corrosion.
If together with aluminum manganese meets, then its existence will be able to strengthen several times alloy with considerable improvement of parameters of hardening. Such composition will remain firm even at very high temperatures. Manganese and aluminum use during creation of kitchen accessories, heating radiators, water systems and conditioners.
When as a part of aluminum alloy silicon meets, resistance to melting of structure strongly decreases. Often such structure is applied to production of castings, fillers for welding or soldering of aluminum.
The known alloys with lead
Lead began to be used by people long ago as this metal is known for the excellent properties: fusibility, hardness and flexibility. Therefore it is rather easy to connect it in alloy to other metals. If to add antimony to lead, then this alloy will become much more solid. Such composition is presented in sheets, the sheet and special pressed forms. Often such alloy can be replaced with connection with lead and calcium. It is also worth noticing that for the stabilizer aluminum is added. For creation of bullets tin is added to lead. Do of such structure also jewelry, dishes and kitchen utensils. By the way, it is one of the few hypoallergenic alloys which is practically not oxidized from aggressive effect of water and salts. In addition, this alloy has antimony, silver, copper and bismuth. Thanks to tin it is possible to receive stronger alloy, much more firmly, but also, lead will connect quite easily to copper and steel.
Despite all prevalence, aluminum was included in the list dangerous, from the point of view of scientists, elements. They proved that aluminum has property to collect in an organism, leading to senile dementia and a sclerosis.
Apparently, alloys with lead and aluminum together with other metals receive excellent physical indicators which, certainly, promotes improvement of quality of the received metal and expansion of the sphere of its application.
