What are the examples of ALLOYS
An alloy is a combination of a metal with another metal (one or more than one) or nonmetal. The most common way to combine metals into an alloy is by melting them, mixing them together, and then allowing them to solidify (not liquid) and cool back to room temperature.
Why Are Alloys Used?Metal alloys are used because they typically have improved mechanical or chemical properties. for example, alloys are formed to improve hardness, strength or resist (prevent) corrosion and much more.
What are Some Common Alloying Elements?There are a wide variety of alloying elements that serve different purposes for different base materials.

- Cast iron is an alloy of iron and carbon
- Bronze - Copper and Tin are the alloying elements
What are Some Common Alloying Elements?There are a wide variety of alloying elements that serve different purposes for different base materials.
- Chromium is a metal frequently used to help alloys resist corrosion. Depending on the material, it can also increase hardness and strength.
- Nickel is a metal often added to materials to increase toughness.
- In steel, copper can increase corrosion-resistance, but can decrease the corrosion-resistance of aluminum.
- Manganese is a metal usually alloyed to improve strength.
- Tungsten is a metal alloying element used to improve wear resistance (especially at high temperatures), toughness, and strength.
- Lead is a metal alloying element that is used to improve machinability. (machinability is when a metal can be worked on by the machine)
- Silicon increases strength and can reduce melting temperature.
- Carbon is a nonmetal alloying element that is a necessary element to manufacture steel. Carbon additions are often used in steel and cast iron alloys to increase strength and hardness.
