Book Free DemoMethod 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.
Ferrous alloys:
It includes Iron as a major component.
Some examples of Ferrous alloys are Stainless Steel, Nickel Steel etc.,
Non-ferrous alloys:
These alloys do not include Iron as a major component.
For example, Aluminium and Copper alloys, etc.,
Copper alloys (Non- ferrous):
Alloys | Uses |
Brass (Cu, Zn) | Electrical fittings, medals, decorative items, hardware |
Bronze (Cu, Sn) | Statues, coins, bells, gongs |
