Material Considerations-Metals Flashcards
Metallic Lustre (definition)
The amount of light that reflects off of a metal
Corrosion resistance (definition)
How susceptible a material
Is to degradation from the elements such as oxygen
Malleability (definition)
A materials ability to deform without breaking or snapping
High density (definition)
A high degree of concentration of atoms in a small space
Density (equation)
Mass/ Volume
Electrical conductivity
How easy it is for electricity to flow through a material
Ductility
How easily a material can be deformed or bent out of shape without snapping or breaking
Strength
How well an object can withstand a bending or breaking force
Hardness
How resistant a material is to pressure from cutting, scratching or wear
Thermal conductivity
The way heat can be transferred through a material
Brittleness
How easily a material will snap or break when bent or impacted
Tensile strength
The maximum amount of pulling stress that a material can withstand before it breaks
Machinability
How easily a material can be cut or shaped
Compressive strength
The resistance of a material to breaking under compression
Ferrous metals
-Metals that contain iron and are magnetic
-Prone to rust
-e.g. steel, cast iron
Non- Ferrous metals
- Do not contain iron
- Not prone to rust
- e.g. copper, silver, gold
Alloys
- A mixture of 2+ metals
