2. Material Specifications

The material used for the part must be specified according to the part's function, strength requirements, and environmental considerations.

• Material Type: Specifies the exact material or alloy used. E.g., "Material: 6061-T6 Aluminum," "Material: 17-4 PH Stainless Steel."
• Hardness: A measure of the material's resistance to deformation. Common hardness scales include Rockwell, Brinell, or Vickers. E.g., "Hardness: Rockwell C 30."
• Material Properties: Describes characteristics like tensile strength, yield strength, elongation, etc. E.g., "Tensile strength: 800 MPa."
• Surface Treatment: The process used to treat the surface of the material to improve properties like wear resistance or corrosion resistance. E.g., "Anodized finish," "Black oxide coating," "Heat-treated to HRC 40."
