Method of making alloys:
(a). The metals are fused together.
Brass is created by fusing zinc and copper.
(b). Finely divided metals are compressed.
Wood metal: A fusible alloy is a powdered alloy of lead, tin, bismuth, and cadmium.
Alloys as solid solutions:
Alloys are solid solutions in which the metal with the highest concentration acts as the solvent and the other metals act as the solute.
Brass is a solid solution of zinc (solute) and copper (solvent) combined together.
Types of Alloys:
Alloys are classified into the following groups based on the presence of Iron.
It includes Iron as a major component.
Some examples of Ferrous alloys are Stainless Steel, Nickel Steel etc.,
These alloys do not include Iron as a major component.
For example, Aluminium and Copper alloys, etc.,
Copper alloys (Non- ferrous):
|Brass (Cu, Zn)||Electrical fittings, medals, decorative items, hardware|
|Bronze (Cu, Sn)||Statues, coins, bells, gongs|
Copper alloy examples
Aluminium alloys (Non- ferrous):
|Duralumin (Al, Mg, Mn, Cu)||Aircrafts, tools, pressure cookers|
|Magnalium (Al, Mg)||Aircraft, scientific instruments|
Aluminium alloy examples
Iron Alloys (Ferrous):
|Stainless steel (Fe, C, Ni, Cr)||Utensils, cutlery, automobile parts|
|Nickel steel (Fe, C, Ni)||Cables, aircraft parts, propeller|
