Here is a common materials hardness table, including Brinell Hardness (HB), Rockwell Hardness (HRC/HRB), Vickers Hardness (HV), Shore Hardness (HS), and Tensile Strength (MPa) reference values.

Common Materials Hardness Comparison Table

Notes

1. Hardness conversion is not absolute; different materials may have variations. For accurate conversion, refer to the ASTM E140 Hardness Conversion Table.
2. Rockwell Hardness (HRC/HRB) is mainly used for metals—HRC is for harder materials, while HRB is for softer materials.
3. Brinell Hardness (HB) is suitable for cast iron, steel, non-ferrous alloys, and softer metals.
4. Vickers Hardness (HV) is used for thin plates, small parts, and a variety of materials.
5. Shore Hardness (HS) is mainly used for high-hardness metals such as carbide and steels.
6. Tensile Strength (MPa) values are estimates and may vary depending on the material.
