EasyWrite the uses of alloys.
(N/A) Alloys are mixtures of two or more metals or a metal and a non-metal. Their uses include:
$1$. They are used to increase the strength and hardness of metals,such as steel (iron and carbon).
$2$. They are used to improve corrosion resistance,such as stainless steel (iron,chromium,and nickel).
$3$. They are used to lower the melting point of metals,such as solder (lead and tin).
$4$. They are used for aesthetic purposes and in jewelry,such as brass (copper and zinc) and bronze (copper and tin).
