About Hardness & Impact Testers

Hardness tests determine the hardness of any material, and impact testing is for determining toughness. Hardness testing assesses the impact of the metal or alloy on permanent indentation, and the depth or size of the indent is measured to determine a hardness value.

Hardness testing enables you to evaluate the strength, ductility, and wear resistance of a material, which can determine whether a material is suitable for the purpose you require. An impact testing machine determines the resistance of a material or component to a rapid load under varying temperature conditions.

Impact testing involves striking a standard specimen with a controlled weight pendulum traveling at a set speed. The amount of energy absorbed in fracturing the test piece is measured indicating the notch toughness of the test material.
