DT p68-72 METALS + METAL ALLOYS

Flashcards covering key concepts related to materials and components in product design.

What are the two main classifications of metals?

Ferrous and non-ferrous.

Define 'ferrous' metals.

Metals that contain iron.

Define 'non-ferrous' metals.

Metals that do not contain iron.

What is functional performance in materials selection?

How the product works or functions.

List three aspects of aesthetics in product design.

Shape, colour, texture.

What is the importance of cost and availability in material selection?

It influences if the product can be manufactured economically and if materials are readily available.

What are physical properties of materials?

Properties associated with the actual make-up or structure of the material, such as density and conductivity.

What are mechanical properties of materials?

Properties associated with how the material reacts to an external force, such as toughness and hardness.

What are the 6Rs in sustainable material selection?

Rethink, reduce, reuse, repair, recycle, refuse.

Give an example of a ferrous metal and its characteristics.

Mild steel; ductile, tough, and corrosion resistant.

What is a metal alloy?

A material made by melting together two or more metals with other elements.

What is bronze primarily made of?

90% copper and 10% tin.

What is brass primarily made of?

65% copper and 35% zinc.

What environmental factors must designers consider when selecting materials?

The source of the material (renewable or non-renewable) and recyclability.

What defines the aesthetic appeal of a product?

Its visual aspects including shape, colour, and texture.
