    True or False

    1. T or F Ferrous metal are those metals with made with iron.

    2. T or F Low carbon steel is steel with less than 0.30% carbon.

    3. T or F 1020 steel has a 20% carbon content.

    4. T or F A high carbon steel has a lower strength than a low carbon steel does.

    5. T or F Generally nonferrous metals are less expensive than ferrous metals.

    6. T or F One problem with nonferrous metals is they tend to corrode.

    7. T or F Copper is much lighter than iron.

    8. T or F The first step in the manufacturing process is the Design phase.

    9. T or F It is important that all factors, service conditions, and uses be considered when selecting a material for a new  product.
