\nPure gold (24 carat) is very soft and malleable, making it unsuitable for crafting durable jewellery. It is typically alloyed with other metals to increase its hardness and strength. Copper is a common metal used for this purpose, along with silver, nickel, and zinc.
\n<\/section>\n
\n– Alloying increases the durability and wear resistance of gold jewellery.
\n– The caratage of gold indicates the proportion of pure gold in the alloy (e.g., 18K gold is 75% gold).
\n<\/section>\n
\nThe choice of alloying metal also affects the colour of the gold. For example, copper gives a reddish tint (rose gold), while silver and palladium create white gold.
