The following table provides an overview of selected materials and their relevant mechanical and technological properties. It serves as a basis for design, material selection, and evaluation in engineering and manufacturing processes. In addition to key parameters such as tensile strength and hardness, manufacturing-related aspects, certification requirements, and application-specific properties are also considered to ensure a reliable and traceable basis for decision-making.
