​Tensile strength

Is a measure of how well or badly it reacts to being pulled or stretched until it breaks.

Some materials, such as plastics, will stretch or elongate before breaking; others, such as metals, will also deform in a similar way but not by as much, and hard materials such as concrete and brick will not deform at all but will simply snap.

​Compressive strength

​Compressive strength is the maximum stress a material can sustain when being crushed.

Hard materials, such as concrete or cast iron, will shatter under compressive stress, while others, like plastics and some metals, may distort in shape.

​Shear strength

​Shear strength is the stress state caused by a pair of opposing forces acting along parallel lines of a material. for example, cutting paper with scissors or ripping a substance apart.

​Ductility of a material

​Ductility is a mechanical property that describes by how much solid materials can be pulled, pushed, stretched and deformed without breaking.

​Malleability of a material

Malleability can be defined as the property of a material, usually a metal, to be deformed by compressive strength without fracturing.
If a metal can be hammered, rolled or pressed into various shapes without cracking or breaking, it is said to be malleable.
