Use: Sterling silver is used in making cutlery, jewelry, musical instruments, and different medical tools. White gold is an alloy of gold with at least one white metal, usually silver, nickel or palladium. Use: Gold-Nickel alloy is hard and strong.
It is used in making rings and pins. Gold-Palladium allow is soft and is used for white gold gemstone settings that increases the strength and durability.
Rose gold is a gold-copper alloy. This alloy was first used in Russia during the nineteenth century and is also called as Russian gold. The other names of rose gold is pink gold and red gold. It is also used in machine shops, technical laboratories, repairing antiques, etc.
Nichrome is various alloys of nickel, chromium, and iron. This alloy is widely used as a resistance wire. It has a high melting point, low cost of manufacture, strength, ductility, resistance to the flow of electrons, and resistance to oxidation. Due to all such properties of nichrome, it is widely used in heating elements. Use: It is used in explosives and fireworks industries, and the making of heating elements. In fact without using an alloy one day is also not passed.
Utensils in the kitchen, vehicles, mobile phones etc are various alloys which are being used and made by human. Even most of the machinery tools and engineering equipments are made up of alloys. An alloy is a metallic intimately mixed solid mixture of two or more different elements, at least one of which is metal.
In molten state alloys are homogeneous and in solid state they may be homogeneous or heterogeneous. Role of Chemistry in Human Life.

As a result, much testing is required in the development of new metal alloys. Melting temperature is a key factor in alloying metals. Galinstan , a low-melt alloy containing gallium , tin, and indium, is liquid at temperatures above 2.
Thousands of alloy compositions are in regular production with new compositions being developed every year.
Accepted standard compositions include the purity levels of constituent elements based on weight content. Some metal alloys occur naturally and require little processing to be converted into industrial-grade materials. Ferro-alloys such as Ferro-chromium and Ferro-silicon, for instance, are produced by smelting mixed ores and are used in the production of various steels. Yet, one would be mistaken to think that alloying metals is a simple process.
For example, if one were to simply mix molten aluminum with molten lead , they'd find that the two would separate into layers, much like oil and water. Commercial and trade alloys generally require greater processing and are most often formed by mixing molten metals in a controlled environment.
The procedure for combining molten metals or mixing metals with non-metals varies greatly depending on the properties of the elements being used. Because metal elements possess great variances in their tolerance of heat and gases, factors such as melting temperatures of component metals, impurity levels, mixing environment, and alloying procedure are central considerations for a successful alloy process.
While elements like the refractory metals are stable at high temperatures, others begin to interact with their environment, which can affect purity levels and, ultimately, the alloy quality.
