Properties and Ecological Footprint
What you need to know
Classify metals into ferrous, non-ferrous, and alloy categories, and understand their extraction from natural ores.
Analyze the strengths, weaknesses, and mechanical properties (tensile strength, toughness, plasticity, malleability, hardness) of ferrous metals like cast iron, mild steel, and stainless steel.
Understand the physical properties of metals, including melting points and thermal/electrical conductivity.
Describe heat treatment processes for ferrous metals, such as annealing, hardening, tempering, and case hardening.
Analyze the properties and appropriate heat treatments (annealing, hardening) for non-ferrous metals including aluminium, copper, brass, bronze, pewter, and silver.
Evaluate the ecological and social footprint of metal production, considering the environmental impact of mining and greenhouse gas emissions.
Apply life-cycle analysis to metal products and emphasize the importance of metal recycling in a sustainable society.
