Ductility is :
The ability of a material to be permanently lengthened without fracturing
The ability for a material to be easily formed without fracturing
The ability of a material to pass heat through it
A material’s resistance to permanent deformation
Hardness is:
The ‘pulling’ force that can be applied to an object without it fracturing
The ability for a material to pass electrical current
The level a material can be hit with a hammer without it breaking
Compressive Force is:
This is the force that tends to squeeze or crush a material
Electrical conductivity is
This force is one that tends to stretch a material
This is the force that tends to slide one face of a material over another
