Study Notes
Metal Classification
- Metals are categorized into ferrous and non-ferrous metals.
- Ferrous metals primarily consist of iron, and are often alloyed with carbon to enhance strength.
- Variations in carbon content significantly impact the properties of ferrous metals, particularly steel.
- Steel grades (low/mild, medium, high-carbon) are differentiated by carbon content, influencing hardness.
- Non-ferrous metals include those found in abundance (zinc, aluminum, copper, lead, tin, nickel) and those found in smaller quantities (cadmium, chromium, platinum, mercury, gold, silver).
Metal Properties and Uses
- Carbon content directly affects steel's hardness and strength.
- Different metals and alloys exhibit diverse characteristics.
- Metal properties determine their suitability for various applications.
Exercises - Diagram Completion
- A diagram is provided requiring the categorization of metals as either found in large or small amounts.
Exercises - Comparative Adjectives
- The exercise requires students to provide comparative forms of adjectives.
- Examples of comparative adjectives are included (e.g., high – higher).
Classification of Materials (Additional Information)
- Geometrical shapes can be categorized (e.g. triangle).
- Matter can be solids, liquids, or gases.
- Tools are categorized as hand tools or machine tools.
- Metals are categorized as ferrous and non-ferrous.
- Specific examples of materials and tools are provided (e.g., hammers, copper, refrigerators, geometrical shapes, etc.).
