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.
