Question
How do the properties of an alloy differ from alloy constituents?
Solution
- The properties of alloys are often greatly different from those of the components.
- For example, gold is too soft to be used without a small percentage of copper.
- A low percentage of molybdenum improves the toughness and wear resistance of steel.
- Bell metal is more sonorous than copper or tin.
- Alnico, an alloy of aluminium, nickel, and cobalt, can lift 60 times its mass.
- These added elements improve hardness, wear resistance, toughness and other properties.
