Engineering Materials & Metallurgy is a core subject in Diploma and Mechanical Engineering that deals with the study of materials, their properties, structure, processing, and applications in engineering. It helps engineers select the right material for the right job to ensure safety, durability, efficiency, and cost-effectiveness.

Engineering Materials:- Engineering materials are the materials used to make machines, tools, buildings, and products. Examples: iron, steel, aluminium, plastic, rubber.
- Types of Engineering Materials
  - Metals
    1. Ferrous metals (contain iron): iron, steel, cast iron
    2. Non-ferrous metals (no iron): aluminium, copper, brass
  - Non-metals
    1. Plastic
    2. Rubber
    3. Glass
    4. Wood
  - Composites
    1. Two or more materials mixed together
    2. Example: fiberglass, reinforced concrete
Metallurgy:- Metallurgy is the science and technology of extracting metals from ores, refining them, and improving their properties.
- Types of Metallurgy
  - Extractive Metallurgy – Extraction of metals from ores
  - Physical Metallurgy – Structure and properties of metals
  - Mechanical Metallurgy – Behavior of metals under force

Difference Between Engineering Materials & Metallurgy

Engineering Materials	Metallurgy
Study of all materials used in engineering	Study of metals only
Includes metals, plastics, rubber, ceramics, composites	Focuses on extraction, processing, and improvement of metals
Deals with types, properties, and uses of materials	Deals with how metals are produced and treated
Helps in material selection for a job	Helps in improving metal properties
Example: choosing plastic or steel for a product	Example: heat treatment of steel
