Hardness
Hardness is a key property that shows how well a material resists being scratched, dented, or permanently changed when force is applied. In manufacturing and materials jobs, it's an important measure of material quality and durability. Professionals use different scales to measure hardness (like Rockwell, Brinell, or Vickers), similar to how we might use different thermometers for temperature. When you see this term in resumes, it usually means the person has experience testing materials, ensuring quality standards, or selecting appropriate materials for specific uses.
