Smelting is the process of extracting metal from its ore by heating it to a high temperature in the presence of a reducing agent, such as carbon.

Refining is the process of purifying metal by removing impurities, such as slag and dross.

Alloying is the process of mixing two or more metals together to create a new material with different properties.

Annealing is the process of heating and cooling metal to change its properties, such as hardness and ductility.

Bronze was the first metal alloy, made from copper and tin.

Steel is the most common metal used today, due to its strength, durability, and versatility.

Rhodium is the most expensive metal, due to its rarity and its use in catalytic converters.

Lithium is the lightest metal, with a density of 0.534 g/cm³.

Tungsten is the strongest metal, with a tensile strength of 1,510 MPa.

Gold is the most ductile metal, meaning it can be drawn into very thin wires.

Gold is the most malleable metal, meaning it can be hammered into very thin sheets.
