- 1Tough, high tensile strength, ductile. Because of low carbon content it can not be hardened and tempered. It must be case hardened. FerrousMild steel
- 2Can be hardened and tempered. Can be brittle. Retains hardness at high temperatures. FerrousHigh Speed steel
- 3Corrosion resistant, builds a layer of oxide on the surface. FerrousStainless Steel
- 4The hardest of the carbon steels. Less ductile, tough and malleable. FerrousHigh Carbon steels
- 5Stronger and harder than mild steels. Less ductile, tough and malleable. FerrousMedium carbon steels
- 6Hard, brittle, strong, cheap, self-lubricating. Available in White, grey , malleable form. FerrousCast iron
- 7Greyish-White, soft, malleable, conductive to heat and electricity, It is corrosion resistant. It can be welded but this is difficult. Needs special processes. Non ferrousAluminium
- 8Ductile, Malleable, Work Hardens. Mixture of one or more metal with one an aluminium. Non ferrousAluminium alloy
- 9Red, tough, ductile, High electrical conductor, corrosion resistant, Can work hard or cold. Needs frequent annealing. Non ferrousCopper
- 10Very corrosive, yellow in colour, tarnishes very easily. Harder than copper. Good electrical conductor. Non ferrousBrass
- 11The heaviest common metal. Soft, malleable, bright and shiny when new but quickly oxidizes to a dull grey. Resistant to corrosion. Non ferrousLead
- 12A layer of oxide protects it from corrosion, bluish-white, easily worked. Non ferrousZinc
- 13White and soft, corrosion resistant. Non ferrousTin
- 14Wide range of colours. Stiff, hard. Tough at room temperature. Can be used outdoors if suitably stabilised. Light weight. Very good acid and alkali resistance. Particularly good for fabricating. ThermoplasticRigid PVC (poly vinyl chloride)
- 15Stiff, strong and tough. Scratches easily. Comes in a wide range of colours. ThermoplasticAcrylonitrile butadiene styrene (ABS)
- 16Hard, tough, rigid, creep resistant. Good bearing surface. Self-lubricating. Resistant to oil, fuels and chemicals. High melting point. Very resilient. Wear and friction resistant. ThermoplasticNylon
- 17Good electrical insulator, good heat resistance. Stiff, hard, brittle alone but strong and resilient when laminated. Resistant to ultraviolet light for outside use. Strongly exothermic, this can lead to cracking. Contracts on curing. Thermosetting PlasticPolyester resin
- 18Wide range of colours. Tough. Good chemical resistance. Good electrical insulator. Flexible, soft. Fades unless light stabilised. Attracts dust unless anti-static. ThermoplasticLow density polythene (LDPE)
- 19Wide range of colours. Fairly stiff and hard. Stiffness and softening point both increase with density. Can be sterilised. Good chemical resistance. High impact and shock resistant. Fades unless light stabilised. ThermoplasticHigh density polystyrene (HDPE)
- 20Stiff, hard glass clear. Very durable outdoors. Easily machined, cemented and polished. Good electrical insulator. Safe with food. Ten times more impact resistance than glass. Splinters easily. Scratches easily. Thermoplastic.Acrylic
or
poly(methyl methacrylate) (PMMA - 21It is used in packaging and labelling, in textiles such as carpets and thermal underwear, stationery, laboratory equipment, loudspeakers, polymer banknotes. It is resistant to a lot of chemical solvents, acids and bases. ThermoplasticPolypropylene
or
polypropene - 22can be a thermoplastic or a thermoset. As a thermoplastic it is used for disposable cutlery, CD and DVD cases, plastic models, smoke detector housings, packaging materials, insulation, foam cupsPolystyrene
