Characteristics and Properties of Materials in Design Flashcards
Natural Timbers Wood sourced from trees
categorized as hardwoods or softwoods.
Softwoods Timber from coniferous trees
faster growing and evergreen.
Hardwoods Timber from deciduous trees
slower growing and durable.
Ferrous Metals Metals containing iron
magnetic
Non-Ferrous Metals Metals without iron
non-magnetic
Thermosetting Plastics Plastics that cannot be reshaped after initial forming.
Thermoforming Plastics Plastics that can be reshaped multiple times when heated.
Common Thermosetting Polymers Includes epoxy resins
melamine
Common Thermoforming Plastics Includes polystyrene
polypropylene
Alloys Mixtures of metals to enhance properties or aesthetics.
Common Alloys Includes brass
