Mechanical Properties: 10 Important Metal Properties You Must Remember

The mechanical properties of the material you are selecting for components are most important for the successful running of a machine.

In engineering, Mechanical Properties of the Metals are those properties that are associated with the ability of the Material to Resist Mechanical Forces and Load.

A material possesses various properties such as chemical properties, magnetic properties, thermal properties, electrical properties, mechanical properties, etc.

Here in this post, I am covering the information about the mechanical properties of a metal. Hope this will help you in designing the machine component.

So, the following are the Important Mechanical Properties of the Metal

  • Strength

The Internal Resistance offered by a part to an externally applied force is called Stress.

It is the ability of a material to resist the externally applied Forces with Breakdown or Yielding.

  • Stiffness

It is the ability of a Material to Resist Deformation under Stress.
  • Elasticity

This is the Property of a Material to regain its original shape after Deformation when the External Forces are removed.
  • Plasticity

It is the Property of Material that retains the Deformation produced under Load permanently.

This Property of Material is important for Forging and Ornamental Work.

Mechanical Properties of the Metal. Strength,Stiffness,Elasticity,Plasticity,Ductility,Toughness,Brittleness,Hardness and Creep.
  • Ductility

It is the Property of Material enabling it, to be drawn into a wire with the application of Tensile Force.

A Ductile Material must be both Strong and Plastic.

  • Malleability

It is the special case of Ductility which permits Material to be rolled or hammered into Thin Sheets.

A Malleable Material should be Plastic but it is not essential to be so strong

  • Toughness

It is the Property of a Material to resist Fracture due to high impact Loads like Hammer Blows.

The Toughness of a Material decreases when it is heated.

  • Brittleness

It is the Property of the Material of breaking material with little permanent distortion.

Brittle Materials when subjected to Tensile Loads snap off without giving any sensible elongation.

  • Hardness

It embraces many different properties such as Resistance to Wear, Scratching, Deformation, etc.

It also means the ability of a Metal to cut another Metal

  • Creep

When a part is subjected to a constant Stress at a High Temperature for a long period of time, it will undergo a slow and permanent deformation called creep.
