3.1 CORE TECHNICAL PRINCIPALS

Understand physical properties such as:

• absorbency (resistance to moisture)

• density

• fusibility

• electrical and thermal conductivity.

You should know and understand working properties such as:

• strength

• hardness

• toughness

• malleability

• ductility and elasticity.

MATHS & SCIENCE

• Scientific vocabulary eg metals/non-metals and physical and chemical differences between them eg types and properties across a range of materials.

• Using materials eg composition of some important alloys eg selection of an alloy for enhanced durability in a particular design situation.
