Material Hardness Charts
Material Hardness Charts are used to measure and compare the hardness of different materials. Hardness is the resistance of a material to indentation or scratching. These charts provide a standardized scale to determine the relative hardness of various substances, including metals, minerals, woods, and plastics. They are commonly used in engineering, construction, manufacturing, and design industries as a reference tool for selecting materials, understanding their durability, and determining suitable applications for different materials.
