Using Metals Flashcards

All 6 cards in this deck

Which properties of aluminium make it suitable for aircraft bodies and overhead power cables?: Low density, resistant to corrosion, and a good conductor of electricity (and its alloys are strong).
Which properties of copper make it suitable for electrical wiring and water pipes?: It is a very good conductor of electricity, ductile, and unreactive with water.
Which properties of gold make it suitable for jewellery and electrical contacts?: It is very unreactive so does not corrode or tarnish, it is shiny, and it conducts electricity well.
Which metals make up brass, and give one use of brass.: Copper and zinc; used for taps, door fittings and musical instruments because it is harder than pure copper.
Which metals make up magnalium, and why is it useful?: Aluminium and magnesium; it has a low density but is stronger than pure aluminium, so it is used in aircraft parts.
Which properties would you look for in a data table when choosing a metal for an aircraft body?: Low density, high strength and good resistance to corrosion.
