Define ductility
Ability of material to deform by bending, twisting or stretching
How does metal benefit from ductility
Ductility in metals increases with temperature
Define malleability
Ability of a material to be permanently deformed in all directions without fracture,
How does temperature affect malleability
Malleability increases with temperature
Define hardness
Ability of a material to resist deformation, indentation or penetration
How do hard materials benefit from hardness
Had materials can resist abrasion, drilling, impact, scratching, and wear and tear
