Question

21 ) Which property of metal is desirable to
make rivet heads?

A ) Ductility
B ) Malleability
C ) Tenacity
D) Machinability​

Answer 1

Answer:

Hardness is an important property: the rivet must be hard enough to pierce the top sheet but sufficiently ductile to flare properly in the bottom sheet. The required hardness, therefore, depends on the hardness of the materials to be joined and is chosen to provide the correct button formation.
