Classification of Common Engineering Materials
-
Metals: Divide into ferrous (iron-based) and non-ferrous (excluding iron) metals, along with their respective alloys. They are known for high strength, ductility, and conductivity.
-
Ceramics: Includes structural ceramics like bricks and tiles often used in buildings, as well as pipes. Characterized by high hardness, resistance to heat and chemicals.
-
Polymers: Composed of large molecular structures mostly made of similar repeating units. Commonly found in synthetic organic materials such as plastics and resins, which offer versatility and lightweight properties.
-
Composites: Materials made from two or more constituent materials with significantly different physical or chemical properties. Examples include:
- Concrete: A mixture of aggregate, cement, additives, and water.
- Disc Brake Pads: Comprise hard ceramic particles within a soft metal matrix; polymer binds the reinforcement.
- Polymer Matrix Composites: Lighter than traditional materials like steel, aluminum, concrete, and brick, making them advantageous in various applications.
-
Advanced Materials: Although not specified, they generally encompass innovative materials with superior properties designed for specialized applications, including nanomaterials and biomaterials.
