When stainless steel is heated, it expands at a rate approximately 150% of that of
steel, which becomes a problem when stainless steel is used in close contact with
other metals. - ANSWER ✓ TRUE
Nonferrous Alloys contain large amounts of iron. - ANSWER ✓ FALSE
Nickel Alloys are used for processes that involve acids and caustics. - ANSWER
✓ TRUE
Brass and Bronze are from the family of copper alloys. - ANSWER ✓ TRUE
Brasses are widely used because of their resistance to corrosion from water
containing various impurities that are corrosive to steel. - ANSWER ✓ TRUE
"Brass" is a term used to describe a family of alloys of copper and zinc. -
ANSWER ✓ TRUE
