Ferrous & Non-Ferrous Metals is one of 9 topics in the Grade 11 Agricultural Technology CAPS syllabus, covered across 3 lessons on Study Vault. Below are real practice questions from this topic with full worked answers.
Sample practice questions
Easy
1. What element must be the main element present for a metal to be classified as ferrous?
Iron
Aluminium
Copper
Zinc
Answer: Iron — Ferrous metals are metals that contain iron as their main element, which is also why they are generally magnetic and prone to rusting.
Easy
2. Which ferrous metal has the higher carbon content and excellent compressive strength, but is brittle under tension or impact?
Cast iron
High carbon steel
Aluminium
Copper
Answer: Cast iron — Cast iron has an even higher carbon content than high carbon steel, giving it excellent compressive strength but making it brittle and prone to shattering under tension or sudden impact.
Medium
3. Name the property that makes high carbon steel suitable for tool cutting edges such as knives and chisels.
Answer: hardness — High carbon steel's increased hardness and wear resistance, from its higher carbon content, make it suitable for cutting edges that must hold a sharp edge.
