AERO 3020 TEST 3 QUESTIONS AND VERIFIED
ANSWERS
5052 - Answers - This alloy is non-heat treatable.
Spray - Answers - This quench method is used when we need to minimize distortion
and are not worried about corrosion resistance.
Wrought - Answers - A material that is shaped by rolling, drawing, or forging.
Pure Aluminum - Answers - A material with a high degree of corrosion resistance, low
mechanical properties, and good thermal and electrical conductivity.
Solution Heat Treatment - Answers - A type of heat treatment for aluminum in which the
metal is raised above the critical temperature, held there for a specific period of time,
and quenched.
Primary Alloy - Answers - The first number in the wrought aluminum alloy identification
code indicates this.
Precipitation Heat Treatment - Answers - A low temperature thermal treatment for
aluminum, also called artificial aging.
99.50% - Answers - The percentage of pure aluminum in 1150 aluminum alloy.
2024 - Answers - This alloy has poor corrosion resistance and contains copper as its
primary allying ingredient.
Alclad Aluminum - Answers - This type of aluminum alloy can only be heated three
times.
Strain Hardening - Answers - Cold working a metal in order to increase the tensile
strength and hardness.
Cold Water - Answers - The harshest quenching method used for aluminum alloys.
Cladding - Answers - A thin layer of pure aluminum rolled onto the surface of an
aluminum alloy in order to increase a corrosion resistance.
Casting - Answers - A part formed by pouring molten metal into a mold.
Artificial Aging - Answers - A low temperature thermal treatment for aluminum alloys
that accelerates the aging process. Also called Precipitation heat treatment.
