Study Notes
What are Alloys?
- Alloys are mixtures of two or more elements; at least one must be a metal.
- Created by melting and mixing component elements.
- Result in materials with improved properties compared to their constituent elements.
Why Make Alloys?
- Improve the properties of pure metals, which can be too soft, brittle, or reactive.
- Increase hardness and strength.
- Prevent corrosion (rust and other degradation).
- Improve appearance (color and finish).
- Enhance other properties like electrical conductivity or melting point.
How Alloys Work
- Added elements disrupt the regular atomic arrangement of pure metals.
- This disruption hinders atomic layer slippage, resulting in increased hardness and strength.
Examples of Alloys
- Bronze: Copper + Tin; used in medals, statues, musical instruments, bearings, and gears.
- Brass: Copper + Zinc; used in musical instruments, decorative items, doorknobs, and electrical components.
- Steel: Iron + Carbon; used in construction (buildings, bridges), machinery, tools, and vehicles.
- Stainless Steel: Iron + Chromium + Nickel; used in cutlery, kitchen sinks, surgical instruments, and industrial equipment.
- Duralumin: Aluminum + Copper + Magnesium + Manganese; used in aircraft bodies and lightweight structures.
- Pewter: Tin + Copper + Antimony; used in decorative items and tableware.
Key Points for SPM Exams
- Definition: An alloy is a mixture of at least one metal and other elements.
- Purpose: Alloys enhance the properties of pure metals.
- Examples: Know the composition and uses of the listed alloys.
- Atomic Structure: Understand how added atoms disrupt pure metal atom arrangement, leading to improved alloy properties.
