Properties and Applications
Material | Property | Application |
Aluminium | High Melting Point | Jet engines so they don't melt as the fuel is burned inside them. |
Glass | Transparent | Used for windows, containers for a light source and lenses to allow light through. |
Aluminium | Low Density | Used in aircraft and cars to keep a low weight. |
Uranium | High Density | Used in bullets and artillery shells to increase the momentum and then the force during a collision. |
Plastic (Polymers) | Low Thermal Conductivity | Clothing, house insulation, handles for pots and pans to prevent extreme temperatures spreading from one region to another. |
Metal | High Thermal Conductivity | Pots and pan to allow then to heat quickly to cook food. |
Plastic (Polymers) | Low Electrical Conductivity | Covering wires to prevent electricity flowing out of the wires. |
Copper | High Electrical Conductivity | Wires to allow electricity to pass through. |
Ceramics (Bricks) | Hard | Walls to prevent damage from impact. |
Metal | Malleable | Wires so they can be bent into new positions without breaking. |
Copper | Ductile | Wires because they need to be stretched into shape. |
Metal | Sonorous | Bells to make a sound when struck. |
