Metal testing is the process of evaluating the properties and quality of metals to ensure they meet specific standards. This can involve various methods, such as tensile testing, which measures a metal's strength and ductility, or hardness testing, which assesses resistance to deformation. These tests help identify the suitability of metals for different applications, from construction to manufacturing. Additionally, metal testing can include chemical analysis to determine the composition of alloys and non-destructive testing techniques that inspect materials without causing damage. These evaluations are crucial in industries like aerospace, automotive, and construction, where material integrity is essential for safety and performance.
