उत्तर

  1. Bronze, an alloy of copper and tin is tough, strong, and corrosion-resistant. It is used for making statues, medals, and trophies.
  2. Cupra-nickel, an alloy of copper and nickel is used for making machinery parts of marine ships, boats. For example, marine condenser tubes.
  3. Stainless steels are used in the construction of the outer fuselage of ultra-high-speed aircraft.
  4. Nichrome, an alloy of nickel and chromium in the ratio 80 : 20 has been developed specifically for gas turbine engines.
  5. Titanium alloys withstand stress up to high temperatures and are used for ultrahigh-speed flight, fireproof bulkheads, and exhaust shrouds.
