Alloys are widely distributed today, and they can be easily found in any field.
But the most popular are still alloys with lead and aluminum.
By the very term "alloy" is meant a material that contains metals and other substances.
Often, more stable metals are becoming additional components for soft and ductile aluminum, but it can also be non-metallic components: boron, sulfur and coal.
Alloys with aluminum content
One of the known alloys where one can meetAluminum - aluminum connection with copper. The resulting metal has a simple formula and strong bonds, due to which the alloy can be used in military and rocket technology, as well as in space vehicles. Use in the composition of copper contributes to improving the resistance to corrosion.
If, together with aluminum, manganese meets,Then its presence can strengthen the alloy several times with a significant improvement in the hardening parameters. It is this composition that will remain solid even at very high temperatures. Manganese and aluminum are used in the creation of kitchen accessories, heating radiators, water supply systems and air conditioners.
When an aluminum alloy is foundSilicon, the resistance to melting of the composition is greatly reduced. Often such a composition is used for the manufacture of castings, fillers for welding or soldering of aluminum.
Known alloys with lead
Lead has been used by people for a long time,Because this metal is known for its excellent properties: fusibility, hardness and flexibility. Therefore, it is quite easy to combine it in an alloy with other metals.
If antimony is added to the lead, then this alloyWill become much harder. Such a composition is presented in sheets, sheet and special compressed molds. Often such an alloy can be replaced by a compound with lead and calcium. It is also worth noting that aluminum is added to the stabilizer.
To create bullets to lead, tin is added. Of this composition do also decorations, dishes and kitchen utensils. By the way, this is one of the few hypoallergenic alloys, which practically does not oxidize from the aggressive action of water and salts. In addition, this alloy has antimony, silver, copper and bismuth. Thanks to the tin, a stronger alloy can be obtained, much harder, and in addition, lead will be quite easily connected to copper and steel.
Despite the prevalence, aluminumCame to the list of dangerous, from the point of view of scientists, elements. They proved that aluminum has the property of accumulating in the body, leading to senile dementia and sclerosis.
As can be seen, alloys with lead and aluminum, together withOther metals receive excellent physical performance, which, of course, improves the quality of the metal and broadens its scope.
