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