PLEASE MARK as BRAINLIST
Explanation:
An alloy is a substance made by melting two or more elements together, at least one of them metal. An alloy crystallizes upon cooling into a solid solution, mixture, or intermetallic compound. The components of alloys cannot be separated using a physical means.
Answer:
Alloys are homogeneous mixture of two metals or one metal and nonmetal.
Brass - Brass is made up of copper and zinc.
Use: Brass is used for decoration for its bright gold-like appearance; for applications where low friction is required such as locks, gears, bearings, doorknobs.
Bronze - Bronze is made up of copper and tin.
Uses: Bronze is used in architecture for structural and design elements, for bearings
Solder - Solder is made up of tin, cadmium, lead and bismuth.
Uses: Hard solders are used for brazing, and melt at higher temperatures. Alloys of copper with either zinc or silver are the most common. In silversmithing or jewelry making, special hard solders are used that will pass assay.
Stainless steel - Stainless steel is made up of chromium, nickel and low carbon content.
Uses: Stainless steels and other corrosion resistant alloys are extensively used in the power generation industry to combat corrosion, particularly at elevated temperatures.
Magnesium - Magnesium is made up of magnesium, aluminium, zinc, manganese, silicon, copper, rare earths and zirconium.
Uses: Magnesium is the lightest of all light metal alloys and therefore is an excellent choice for engineering applications when weight is a critical design element.
Duralium - Duralium is made up of copper, magnesium, manganese and silicon.
Uses: It is used for making wire, bar and rods for the screw machine products. It is used in places where good strength and good machinability are required.
