Properties of Materials II
Performance Objectives
Students should be able to:
- Identify, classify and describe the properties of metals
Content
Metals are another material used in the construction of things and they can be identified using their identity, colour/lustre, fusibility, magnetic effect, conduction of heat and sound.
There are about 103 elements, 92 of which are naturally occurring. Metals and non-metals are characterized by distinctly different physical and chemical properties. At present about 80 metals are known to us. Metals can be shaped like clay, are heat-resistant, and are not fragile.
A metal is a material (an element, compound, or alloy) that is typically hard when in a solid-state, opaque, shiny, and has good electrical and thermal conductivity. Metals are generally malleable—that is, they can be hammered or pressed permanently out of shape without breaking or cracking—as well as.... View More
