Metals Flashcards
Aluminium
Lightweight, ductile, malleable, corrosion resistant, conductor, can be mig and tig welded.
Used in drinks cans, aircraft bodies, bike frames, window frames, packaging and baking foil
Copper
Ductile, malleable, tough, corrosion resistant, a good conductor, can be soldered and brazed.
Used in electrical wire, pec, water pipes, hot water tanks and central heating pipes
zinc
A low melting point, corrosion resistant
used in for galvanising steel as a protective coating for dustbins, bucks, farm gates; intricate die casting
Titanium
Similar strength to steel but more lightweight, corrosion resistant
used in joint replacements, tooth implants, spectacle frames, aircraft, golf clubs
Low carbon steel
Ductile, high tensile strength, tough, malleable, poor corrosion resistance. (0.15-0,3% carbon)
Used in nuts, bolts, washers, screws and car bodies.
Medium Carbon steel
Harder but less ductile than lcs, malleable and tough
(0.3-0.7% carbon)
Used in springs and gardening tools
Cast iron
Hard outer skin but brittle, good under compression
(3.5% carbon)
Used in disk breaks, machine parts, engine blocks,
Stainless steel
Tough, hard, corrosion resistant
18% chrome, 8% nickel
Used in sinks, cutlery
High speed steel
Hard, tough, high level of resistance to frictional heat
18% tungsten, 4% chromium
Used in tool blades, drill bits
Bronze
Tough, corrosion resistant, can be cast
90% copper, 10% tin
Used in statues, coins and bearings
Brass
Corrosion resistant, conductor, low melting point, becomes harder when worked
65% copper, 35% zinc
Used in boar fitting, door furniture, taps and ornaments
Pewter
Malleable, low melting point, casts well
85%-99% tin with remainder of copper and antimony
Used in flasks, photo frames, sports trophies
Sheets
Large flack sections between 1mm to 3mm thickness
Plate
3mm thick narrower than sheet metals
