They're malleable 3. They're good conductors. 1 of 33 Name one thing that transition metals are good for because they are strong and malleable. They can be used to make things like bridges or car bodies. 2 of 33 Name one thing transition metals are good for because they are good conductors of heat. They can be used to make things like a saucepan base. 3 of 33 Name one thing transition metals are good for because they are good conductors of electricity. They can be used to make things like electrical wires. 4 of 33 Name four properties of copper. 1. It is a good conductor of electricity. 2. It's hard and strong 3. It can be bent. 4. It doesn't react with water. 5 of 33 Name three properties of aluminium. 1. It is corrosion-resistant 2. It has a low density and is light. 3. It forms strong alloys. 6 of 33 Name three properties of titanium. 1. It has a low density. 2. It is very strong 3. It is corrosion-resistant. 7 of 33 Name a use for copper and two reasons it is good for this job. Copper is great for plumbing. It can be bent to make pipes and tanks, ad it doesn't react with water. 8 of 33 Name a use for aluminium and three reasons it is good for this job. It is used to make aeroplanes. It's strong and can be bent into shape. It's also light. 9 of 33 Name a use for titanium and three reasons it is good for this job. It is used by doctors to make replacement hips for people. It won't corrode when it comes in contact with water. It's also light and not too bendy. 10 of 33 Define an alloy. A metal made by combining two or more metallic elements, usually to give greater strength or corrosion resistance. 11 of 33 Iron straight from a blast furnace is only how much % iron? 96% 12 of 33 What is in the other 4% of impure iron? Impurities such as Carbon. 13 of 33 What is the name of the property that makes iron easy to break? Brittle. 14 of 33 Most pure iron is changed into alloys. Such as...? Steels. 15 of 33 How are steels formed? By adding small amounts of carbon and sometimes other metals to the iron. 16 of 33 Name three types of steel. 1. Low carbon steel 2. High carbon steel 3. Stainless steel 17 of 33 How much % of low carbon steel is carbon? 0.1% 18 of 33 How much % of high carbon steel is carbon? 1.5% 19 of 33 How is stainless steel created? Chromium added, and sometimes nickel. 20 of 33 What are the properties of low carbon steel? Easily shaped. 21 of 33 What are the properties of high carbon steel? Very hard, inflexible. 22 of 33 What are the properties of stainless steel? Corrosion-resistant. 23 of 33 Name a use for low carbon steel. Car bodies. 24 of 33 Name two uses for high carbon steel. Blades for cutting tools, bridges. 25 of 33 Name two uses for stainless steel. Cutlery, containers for corrosive substances. 26 of 33 Why are alloys more useful than pure metals? They are harder. 27 of 33 What is the name of the alloy created by combining copper and nickel? Cupronickel. 28 of 33 What is the use of cupronickel? It is used to make silver coins. 29 of 33 What are gold alloys used for? To make jewellery. 30 of 33 Why can't pure gold be used to make jewellery? It is too soft. 31 of 33 Which metals are used to make a gold alloy? Copper, silver, nickel. 32 of 33 What are aluminium alloys used for? To make aircraft. 33 of 33
