Bulk Properties of Copper Density and Resistivity

Density and resistivity of materials are called bulk properties: their value doesn''t depend on the size or shape of a particular sample – only on the material itself. When we say that copper is a heavier metal than aluminium, we are comparing their densities. In a similar way, when we say that copper is a better conductor than aluminium, we ...

Compressive strength

Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to Tensile strength which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart). In the ...
