| What is an Alloy? | -This is simply a Mixture of 2 or more Metals, or Metal and Non-Metal |
| Why are Alloys useful? | -They have Different Properties that are Different from the Metals they were Made From, and they may be Better. |
| Steel: What is it, Why is it good and Where is it found? | -Steel is simply an Alloy of Iron and Carbon
-It is more Harder and Stronger than Iron, and will not really Rust that much.
-Carbon Percentage in the Steel is Very Detrimental
-Girders, Bridges, Engine Parts, Cutlery, Washing Machines ... are all made from Steel |
| Brass: What is it, Why is it good and Where is it Found? | -Brass is simply an Alloy of Copper and Zinc
-Brass is Harder than the Metals, and its Other Properties are just a Mixture
-Brass is used for Musical Instruments [Trumpets, French Horns..] and Fixtures and Fittings [Screws, Doorknobs] |
| Bronze: What is it, Why is it good, and Where is it Found? | -Bronze is simply an Alloy of Copper and Tin
-Its much more Harder and Stronger compared to Tin, and its more Resistant to Corrosion than that of Tin or Copper
-Bronze is found to make Springs, Bells, Sculptures and Motor Bearings |
| Solder: What is it, Why is it good, and Where is it Found? | -This is can Alloy of Lead and Tin [Usually]
-This doesn't have a Melting Point that is Definite- it just Gradually Solidifies as it Cools Down. This makes it Easier to Join Metal Things together.
-It can be used in Components, and its Low Melting Point will mean it won't deform Other Components |
| Duralumin: What is it, Why is it good, and Where is it Found? | -This is an Alloy of Aluminium [94%] and Copper [4%] and Magnesium [1%] with very low Amounts of Manganese.
-It has a Very Low Density, making it Light but is Stronger than Aluminium
-This makes it Perfect for Aeroplanes and other Aircraft |
