The electrical conductivity of a metal is often very much decreased by alloying with it even small quantities of another metal.
This explains the failure of boats built of commercially pure aluminium which have been put together with iron or copper rivets, and the decay of other boats built of a light alloy, in which the alloying metal (copper) has been injudiciously chosen.
Alloying elements can be used to control the bulk microstructure of a steel and hence its hardness.
The effects of alloying palladium on the associated cyclization chemistry will be discussed.
Gold can be made tougher and more durable by alloying with other metals.
