Compressive strength : Maximum stress a material can withstand before compressive

failure (MPa)The compressive strength is the capacity of a material or structure to withstand

loads tending to reduce size. It can be measured by plotting applied force against

deformation in a testing machine.

COMPRESSIVE STRENGTH

Tensile strength : Maximum tensile stress a material can withstand before failure (MPa). Ultimate tensile strength (UTS), often shortened to tensile strength (TS) or ultimate strength is the maximum stress that a material can withstand while being stretched or pulled before failing or breaking.

TENSILE STRENGTH 

Ductility : Ability of a material to deform under tensile load (% elongation). Ductility is a solid material's ability to deform under tensile stress; this is often characterized by the material's ability to be stretched into a wire

DUCTILITY 

Malleability: The similar property, is a material's ability to deform under compressive stress; this is often characterized by the material's ability to form a thin sheet by hammering or rolling 

MALLEBILITY

Fatigue : Maximum stress a material can withstand under repeated loading (MPa). Fatigue limit, endurance limit, and fatigue strength are all expressions used to describe a property of materials

FATIGUE

Toughness : Energy absorbed by unit area before the fracture of material. Fracture toughness is a property which describes the ability of a material containing a crack to resist fracture, and is one of the most important properties of any material. The fracture toughness of a material is determined at which a thin crack in the material begins to grow. and is a measurement of the energy required to grow a thin crack.

TOUGHNESS 

Hardness : Ability to withstand surface indentation (e.g. Brinell hardness number) Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied.  there are different measurements of hardness: scratch hardness, indentation hardness, and rebound hardness..

HARDNESS

Plasticity : Ability of a material to undergo irreversible deformations. . plasticity describes the deformation of a material undergoing non-reversible changes of shape in response to applied forces.
