Theory:

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.
  
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):

Uses
Brass (Cu, Zn)Electrical fittings, medals, decorative items, hardware
Bronze (Cu, Sn)Statues, coins, bells, gongs
