🧪 Properties and Uses of Different Types of Materials
Materials can be grouped by type (metals, plastics, ceramics, etc.), each with unique properties that make them suitable for specific uses.
🧱 1. Metals
- 🔹 Properties:
- Strong and durable
- Good conductors of heat and electricity
- Malleable (can be shaped)
- Often shiny (lustrous)
🔧 Uses:
- Building structures (steel, iron)
- Electrical wiring (copper)
- Tools and machines (aluminum, titanium)
- Jewelry (gold, silver)
🧴 2. Plastics (Polymers)
- 🔹 Properties:
- Lightweight
- Durable and waterproof
- Poor conductors
- Can be molded easily
🔧 Uses:
- Packaging (bottles, bags)
- Household items (containers, furniture)
- Electronics (insulation, casings)
- Medical devices (syringes, tubing)
🏺 3. Ceramics
- 🔹 Properties:
- Hard and brittle
- Heat-resistant
- Poor conductors
- Chemically stable
🔧 Uses:
- Tiles and pottery
- Bricks and toilets
- Engine parts and electronics
- Heat shields (spacecraft)
🧽 4. Composites (Mixed Materials)
🔹 Properties:
- Combine the best features of different materials
- Strong, lightweight, and durable
🔧 Uses:
- Aircraft and car bodies (carbon fiber, fiberglass)
- Sports equipment (tennis rackets, bikes)
- Building materials (concrete, reinforced plastic)
🌿 5. Natural Materials
🔹 Properties:
- Found in nature
- Biodegradable
- Varies depending on the material (e.g., wood vs. wool)
🔧 Uses:
- Wood: furniture, buildings
- Cotton: clothing, fabrics
- Leather: shoes, bags
- Wool: warm clothing, insulation
🧠 Summary Table
