Medicine

Precious metals are very widely used here. And their value in medicine can be much higher than in a variety of jewelry. Indeed, what can be more valuable than life and health? The use of precious metals in medicine is often due to the fact that these metals are inert, that is, they are not too eager to react with other elements in the environment (and, accordingly, in the patient's body). So gold, palladium, platinum are used in dentistry, from iridium hypodermic needles are made, alloy with platinum has perfectly proved itself in the manufacture of surgical instruments, and isotopes of iridium are used in radiation therapy.

The spectrum of the use of non-ferrous metals is unusually wide and is due to the unique physical and chemical properties of these metals. They find application in jewelry, in mechanical engineering, electronics, aircraft building, construction and much more. Non-ferrous metals were the first that a man began to smelt and use for his needs. The use of metals in industry made possible what they could not have dreamed of without - the ductility and plasticity of metals made it possible to forge and form details of enormous complexity, the alloys were able to withstand the conditions of salt water, low and high temperatures, corrosive media, radiation and other influences that gave man the opportunity to dive into the sea depths, rise above the earth and reach truly cosmic heights. Thus, the use of non-ferrous and ferrous metals is inextricably linked with the development of culture, science, and humanity as a whole. We can not imagine our life without the use of metal in all its forms and manifestations - from kitchen utensils to the most complicated apparatuses and machines. And our task is to preserve carefully the natural reserves of these valuable substances, to properly recycle, so that the metal does not continue to act as an enemy, which kills the ecology of the planet, and hence all living creatures, but also helps alleviate its quality , make the world better.
