Metals Flashcards
What two groups can metals be grouped into?
Ferrous and non-ferrous
What are ferrous metals?
metals or alloys that contain iron
What are non-ferrous metals?
metals or alloys that do not contain iron
Properties of ferrous metals?
most are magnetic and prone to corrosion (rust)
Name 3 ferrous metals?
-Cast iron
-Low carbon steel
-High carbon steel
Properties of cast iron?
-Strong when compressd
-brittle
-cheap
Uses of cast iron?
bench vices, car brake discs, manhole covers
Properties of low carbon steel?
-Good tensile strength
-Tough
-Malleable
Uses of Low carbon steel?
car bodies, screws, nuts, bolts, nails
Properties of High carbon steel?
harder than low carbon steel, can be hardened, less malleable
Uses of High carbon steel?
tools, e.g. chisels, files, saws, drills
Properties of non-ferrous metals?
corrosion resistant, more malleable and majority are not magnetic
Properties of Aluminium?
lightweight, corrosion resistant, good thermal and electrical conductor, soft, malleable
Uses of aluminium?
aircraft bodies, cans and high-end car chassis
Properties of Copper?
soft, malleable, ductile,, good electrical conductor
Uses of Copper?
electrical wiring and pipes
Properties of Zinc?
-high level of corrosion resistance
-easily worked
-low melting point
Uses of Zinc?
coating steel (e.g. on nails, buckets and watering cans)
Properties of Tin?
-malleable
-ductile
-low melting point
-corrosion resistant
Uses of Tin
-Coating on food and drinks cans
-Solder

What are some stock forms of metals?
Sheets
Plates
Bars
Tubes
Explain cellulose and acrylic paints
Provide colour and a textured finish, while also providing a barrier against corrosion. Paints are primarily used on low cost material such as steel.
Explain electroplating
Uses a metal to coat a base metal, to provide a protective layer and to give a greater aesthetic appeal. Commonly used metals include silver, gold, zinc, copper and tin
