Materials like gold and copper can be bent; they are malleable or ductile.
Materials that are brittle and break easily are non-ductile. Conventional concrete is non-ductile (and breaks under stress of earthquakes)(or other tensile challenge).
Metal (steel) mesh or synthetic fibers are added to concrete to make it more ductile.

Metals are good electrical and heat conductors. They are malleable, ductile, and generally solid at room temperature. Nonmetals are poor conductors of heat and electricity. They form brittle solids and are nonductile. They are generally liquids or gases at room temperature.
Metals * Good electrical conductors and heat conductors. * Malleable - can be beaten into thin sheets. * Ductile - can be stretched into wire. * Possess metallic luster. * Opaque as thin sheet. * Solid at room temperature (except Hg). Nonmetals * Poor conductors of heat and electricity. * Brittle - if a solid. * Nonductile. * Do not possess metallic luster. * Transparent as a thin sheet. * Solids, liquids or gases at room temperature
Metal Physical Properties lustrous (shiny) good conductors of heat and electricity high melting point high density (heavy for their size) malleable (can be hammered) ductile (can be drawn into wires) usually solid at room temperature (an exception is mercury) opaque as a thin sheet (can't see through metals) metals are sonorous or make a bell-like sound when struck Nonmetal Physical Properties not lustrous (dull appearance) poor conductors of heat and electricity nonductile solids brittle solids may be solids, liquids or gases at room temperature transparent as a thin sheet nonmetals are not sonorous
I would describe Nonmetallic behavior as primarily being how nonmetals deal with electrons: nonmetals would either ACCEPT electrons from a metal to form an ionic bond OR SHARE electrons with another nonmetal in a covalent bond. So typically, nonmetals aren't going to donate electrons in ionic bonds, like metals do (metallic behavior).
Metals * Usually have 1-3 electrons in their outer shell. * Lose their valence electrons easily. * Form oxides that are basic. * Are good reducing agents. * Have lower electronegativities. Nonmetals * Usually have 4-8 electrons in their outer shell. * Gain or share valence electrons easily. * Form oxides that are acidic. * Are good oxidizing agents. * Have higher electronegativities. Metals * Good electrical conductors and heat conductors. * Malleable - can be beaten into thin sheets. * Ductile - can be stretched into wire. * Possess metallic luster. * Opaque as thin sheet. * Solid at room temperature (except Hg).
