Help me with some questions please.?

1. Which type of Ferrous metal would be suitable to make tough kitchen sink units from? The surface would have to withstand shocks and wear and water flooding.

2. Name the Ferrous metal that most work-shop tools are made from?

3. Give an example of a suitable ferrous metal that may be used to make garden tools?

4. Why are the majority of wire electrical cables made from copper?

5. Name a Non-ferrous metal that is used to protect dental nurses, doctors and dentists from the harmful radiation that is given off when using X-rays?

6. How are steel corrugated roofs made water resistant?

8. Name a Non-Ferrous metal that is suitable to make ornaments ? Name the industrial process used?

9. Give the name of the metal that is suitable to make jewellery from? Why is it a good choice?

10. Why is High tensile steel an ideal metal to make car gears from?

1 stainless steel

2 high speed steel (hss)
if he is talking about wrenches and screwdrivers it might be high carbon steel (over 1020; heat treated hardened steel)

3 1018 or 1020 (carbon steel); might also be called low carbon steel or leaded steel even though lead is frowned upon in todays world.

4 good conductivity (aluminum is good but yields over time)

5 lead

6 galvanizing (coated with zinc or other metal) or paint

7 easily shaped and light weight (not totally sure if that is right)
and they don't rust.

8 gold, silver, or copper; goldsmith or silversmith could also be blacksmith. The industrial process part has me a bit confused, maybe he is looking for "forging"?

9 gold, easily shaped or molded and low reactivity to the skin. reactions to gold are usually from alloys.

10 because of the tensile forces on the teeth of the gears. Think of tensile strength as pulling apart.
