Facts You Should Know About Metals

Metals have been an important part of world development for the tools that we need, the buildings that protect us, the vehicles that transport us, telecommunication and technology, and that is just scratching the surface. To know the value of metal is to know the variations of strength, durability, versatility, and electrical conductivity. Different types of metal are important for different projects and components. It’s amazing to think of the abundance and diversity, when about 75 percent of know elements on the periodic table are metals. These are just a handful of facts that may just blow your mind!

  • Alloys are a combination of 2 or more metals, or one nonmetal and one metal.
  • Steel was first used for skyscrapers
  • Steel is also the most recycled metal – more than all of the paper, plastic, aluminum, and glass combined.
  • Mercury has the lowest melting point of all metals. At room temperature it remains in liquid state.
  • Silver is the best conductor of electricity over all other metals
  • Steel and iron expand when heated, this includes seasonal temperature changes – so watch your structure for stretching and shrinking!
  • Iron makes up most of the Earth’s core and is easily the most abundant metal on this planet.
  • Explosion welding (unlike other methods of welding,) is a powerful process that can fuse nearly any type of metal together.
  • Notice in the doorknobs in hospitals, offices, and other public buildings? Most are made of copper or a copper alloy, brass; this is because they are known to have anti-microbial properties.
  • Up until the late 400’s AD, there were only 7 known metals, silver, gold, bronze, iron, copper, lead, and mercury.
  • Silver, gold, and platinum are precious noble metals which resist rusting and corrosion when exposed to moist air.
  • The most commonly used metals are ironaluminumcopperzinc, and lead.
