What material property allows it to be hammered or rolled into thin sheets_________________?
Show answer Hide answer
Answer: A. malleability
Explanation
Malleability is the mechanical property that allows a material to be hammered or rolled into thin sheets. Malleable materials can withstand high compressive deformation without cracking or fracturing. This property enables metals to change shape permanently under rolling or pressing operations. Gold and lead are prime examples of highly malleable metals that can be beaten into microscopic foils. Malleability generally increases as metal temperatures are raised during hot working processes. Crystal slip systems allow atoms to slide over each other during compressive shaping.
Sheet metal stamping and forging industries rely heavily on the malleability of working alloys. Manufacturing automobile body panels requires highly malleable steels that stretch without tearing. Blacksmiths utilize the high malleability of heated iron to shape tools and decorative hardware. Ductility allows materials to be drawn into thin wires under tensile pulling forces. Plasticity is the general ability of a material to undergo permanent deformation without breaking. Elasticity describes temporary deformation that recovers fully once the applied load is removed.
