  1. Alloys By: Jonathan Rhodes

  2. What Are Alloys? • The book defines an Alloy as a solid solution consisting of atoms of different metals. • Another source simply states that an alloy is a metal composed of more than one element.

  3. Common Examples of Alloys • Steel as seen in the picture is made of iron and carbon. • Brass is made of copper and zinc. • Solder is made of tin and lead. • Bronze is primarily made of copper.

  4. Soldering • The alloy, solder is used for a process called soldering. • Soldering is when two or more metals are joined together by a filler metal with a low melting point. • The pipes in the picture below were soldered together.

  5. Keys and Locks • Brass is used in keys and locks. • It is formed into the shape of a specific key blank which is then cut to make a unique key. • Brass is also used for the pins that make a lock’s cylinder work.

  6. Infrastructure • Stadiums, skyscrapers, bridges, airports, and other buildings use steel as support. • Steel is also used in screws, bolts, and nails for within the infrastructure.

  7. Relation to Chemistry Class • Alloys are formed by two metals, which relates to compounds of two or more elements. • I n order for alloys to be created, a chemical reaction must occur, resulting in a chemical change. • Alloys are in fact solid solutions which are one of the first subjects we learned about.

  8. Questions • What does an alloy consist of? • How is steel used for infrastructure?
