hardness-of-a-material

When evaluating materials for engineering or industrial use, durability against wear and deformation plays a decisive role, which is why the hardness of a material is closely examined during selection and testing. This property reflects a material’s resistance to scratching, indentation, and surface damage under applied force, directly affecting its lifespan and performance in real-world applications. From metal tools and machine parts to construction components and consumer products, hardness helps determine suitability for specific operating conditions. However, hardness does not exist in isolation; it must be balanced with toughness and flexibility to avoid premature failure.
