metals and alloys Flashcards
what is a ferrous metal
Metals that contain iron. Besides iron itself, all ferrous metals are alloys.
what are the properties and uses of iron
Heavy and strong, iron is most commonly found nowadays in various alloys. Used in heavy kitchen skillets, radiators and fireplaces in older houses.
what are mild steel properties and uses
General purpose metal for general engineering. Good strength and cold-forging properties. Corrodes quickly without protection. Can be welded and braised.Used in structural components, general workshop projects.
high speed steel properties and uses
Very hard, resistant to frictional heat.Used in lathe cutting tools, drills, milling cutters.
high carbon steel properties and uses
Very hard, difficult to cut, easily joined by carbon treatment.Used in hand tools, hammers, screwdrivers, chisels.stainless
stainless steel properties and uses
Hard, tough, resists wear, corrosion resistant, difficult to cut.Used in dishes, sinks, teapots, cutlery.
non-ferrous meaning
Metals that do not contain iron
aluminium uses and properties
High strength to weight ratio, light, soft, difficult to join. Used in kitchen utensils, packaging, cans, foils, window frames.
copper properties and uses
Bright and decorative colour when polished. Corrosion resistant. Soft and easy to work by hand. Good heat and electrical conductor.
gold uses and properties
Soft, malleable, ductile, often alloyed to give more strength, doesn’t corrode or tarnish.Used in jewellery, electronics, hi-fi equipment, dentistry.
tin properies and uses
Soft, corrosion-resistant pure metal. Silver-coloured and bright when polished. Can be worked by hand. Used to plate other metals.
brass properties and uses
Corrosion resistant, casts well, work-hardens, polishes well.Used in castings, boat fittings, ornaments.
bronze properties and uses
Corrosion resistant, casts well, work-hardens, polishes well.Used in castings, boat fittings, ornaments, statues.
pewter properties and uses
Soft alloy of tin, copper, lead or silver. Low melt temperature makes it ideal for casting projects.Used in sand-casting, old-fashioned tableware.solder:
solder properties and uses
Soft alloy, usually made from copper and tin. An added substance, called flux, allows the solder to flow over other metals when heated.Used in jewellery manufacture, electronics.
