QUIZZES WITH ACTUAL RIGHT ANSWERS .
Ferrous Metals - correct Answers -The word 'ferrous' comes from the Latin word ferrum, which
means, 'containing iron.' One sure way to tell if a metal is ferrous is to test for magnetic
properties. Ferrous metals are generally magnetic by nature and have high tensile strength,
making them ideal in construction.
Most common ferrous metals: - correct Answers -cast iron, wrought iron, alloy steel, carbon steel
This is the backbone of building and construction, and is quite possibly the most widely used
material by engineers and in construction. - correct Answers -carbon steel
Non-Ferrous Metals - correct Answers -Non-ferrous metals have advantages over ferrous metals
because they are lighter in weight and more malleable; they don't contain iron.
Primary examples of non-ferrous metals are: - correct Answers -copper, aluminum, nickel, zinc,
lead, tin, gold, silver
platinum, and palladium.
Aluminum - correct Answers -is lightweight and can be easily cast, forged, machined and
welded.
Its ductility, malleability, and high conductivity make it the principal metal in sheet roofing,
bearings, pipes, statues, and the electrical industry in the form of wire and other conductors. -
correct Answers -Copper
Zinc - correct Answers -most widely used to galvanize the protective coating of iron or steel to
prevent rust.

, Alloy - correct Answers -a mixture of two or more elements, where at least one element is a
metal.
Brass - correct Answers -used to make coins and musical instruments
Materials of a brass: - correct Answers -Copper and Zinc
Bronze - correct Answers -used to make propellers for ships, bells
Materials of a bronze: - correct Answers -Copper and Tin
Duralumin - correct Answers -used to make Aircraft parts
Materials of a duralumin: - correct Answers -Aluminum and copper
Solder - correct Answers -used to join copper pipes and electrical components
Materials of a solder: - correct Answers -Tin and Lead
It exhibits excellent mechanical strength and creep resistance at high temperatures, good surface
stability, and corrosion and oxidation resistance. - correct Answers -Superalloy
Base alloying elements of a superalloy: - correct Answers -nickel, cobalt, or nickel-iron
Superalloy - correct Answers -It is used at high temperatures, often in excess of 0.7 of the
absolute melting temperature, frequently operate at temperatures exceeding 1050 °C with
occasional working at temperatures up to the value of 1200 °C. High strength, good fatigue,
creep, and oxidation resistance, good corrosion resistance when working at elevated
temperatures for extended periods of time are the prime design criteria.
