materials

?
OAK (hardwoods)
strong and chars. oak woods adds special aroma to beverages such a whiskey as they are used to make the barrels. ideal for flooring due to its light brown colour and strength.
1 of 22
TEAK (hardwood)
very durable and resists outdoor conditions well because of its high content of resin. can be flexible and less resistant to impact than oak. has a yellow/ brown colour. it is straight grained with a rough oily texture. expensive. furniture, joinery
2 of 22
BEECH (hardwood)
a close- grained strong hard though wood. warps easily because on the water inside the wood. beech is white to pinkish- brown in colour. beech can be mainly used as veneer for either flooring or work surfaces.
3 of 22
PINE (softwood)
they can reach from 10 to 245 feet in height. wood off pines is used in the manufacture of furniture, roofs, floors, railroad trails. strong to hold together securely and safely. inexpensive and dent shrink or swell
4 of 22
SPRUCE (softwood)
grow to the height of 60 to 200 feet. it is the tallest species. light and soft, good strength and elasticity. properties for its relatively light weight. won't erode and wear over time. water resistant
5 of 22
FIR (softwood)
the straight, fine-grained wood, tight knots and the yellow to reddish brown colour which makes it quite stylish. left unstained and simply varnished to reveal its natural colour and grain
6 of 22
PLYWOOD (man made sheet based materials)
uses laminated veneers to produce large sheets of stable material with a natural wood finish. layers of hardwood veneer are bonded together with. can b curved
7 of 22
MDF (man made sheet based materials)
procured by tiny particles of timber glued together and them compressed with a resin adhesive. easily damaged by moisture. contains no knots or rings - more uniform. takes paint well but needs to be sealed or it may warp or expand.
8 of 22
BLCOKBOARD (man made sheet based materials)
lightweight - so it can be easily moved e.g. doors. stripes of softwood glued side by side and then sandwiched by sheets of veneer. easy to work with as it can take nails and screws
9 of 22
CAST IRON (ferrous metals)
heated until it liquefies, poured into mould to solidify. iron is one of the most available +widely used. less ductile, it is brittle sue to its higher carbon content. poor corrosion resistance. it has a low melting point.
10 of 22
LOW CARBON STEEL / MILD STEEL (ferrous metals)
lower carbon content gives this steel high ductility and toughness. used with large quantities of steel e.g. as structural steel. cheap but poor corrosion resistance.
11 of 22
HIGH CARBON STEEL (ferrous metals)
the high carbon content makes the steel harder but less ductile. manufacture of hand tools. high wear resistance.
12 of 22
STAINLESS STEEL (ferrous metals)
resistant to wear and corrosion. waterproof. malting point of 1400 degrees c. very tough and won't rust. used for culturally and medical equipment.
13 of 22
ALUMINIUM (non ferrous metals)
strong, low weight corrosion resistance and recyclable. extremely energy intensive to produce
14 of 22
COPPER (non ferrous metals)
reddish brown in colour, darkens slowly when in contact with air. malleable, ductile , relatively soft. good conductor of electricity and heat. good corrosion resistance.
15 of 22
BRONZE (alloys)
harder than brasses. most are produced by melting the copper and adding the desired amounts of tin, zinc, ect.. often used for blazing and joining two metals together. never rusts. fairly inexpensive, ductile, corrosion resistant.
16 of 22
TUNGSTEN (alloys)
resistant to attach by alkalis, oxygen and acids. conductive, anti- corrosion used to make electrical wiring. melting point at 3,422 c.
17 of 22
BRASS (alloys)
good conductor of heat and electricity. resistant to corrosion. used for decoration (aesthetics)
18 of 22
POLYETHYLENE TEREPNTHALATE (PET) (thermoplastics polymers)
used to manufacture blow moulded bottles for soft drinks. semi rigid to rigid, its lightweight. commonly recycled. first developed by NASA
19 of 22
HIGH DENSITY POLYETHYLENE (HDPE) (thermoplastics polymers)
large strength to density. used for a variety of food and drink packaging. commonly recycled. waxy to the touch. milk bottles
20 of 22
POLTVINYL CHLORIDE (PVC) (thermoplastic polymers)
comes in two basic forms: rigid and flexible. versatile and low costs. commonly recycled, however health concerns.
21 of 22
LOW DENSITY POLYETHYLENE (LDPE) (thermoplastics polymers)
lightweight with low stiffness and rigidness. most food safe plastics. flexible and recyclable. used for supermarket bags. chemical resistant. cheap and easy to produce.
