Aluminium Alloys. Sci. Some conditions, especially the incidence of cold work, can change the relationship between the tensile strength and hardness profoundly. April 15, 2011. The strength of a material can refer to yield strength, ultimate strength, or fracture strength. Phys. If you have the Brinell hardness in a different range, refer to a hardness conversion scale to convert it. Tensile Strength : Gives you the material’s bulk property, like toughness. Tensile strength Kg/mm²: Rockwell hardness: Indentation diameter mm. Relation between tensile strength and hardness of aluminum alloys.

The correlations between Rockwell hardness and tensile strength of cracked aluminium plates repaired with composite patches were studied. Brinell Hardness Strength is indicates the ability of solid material to withstand deformation under external load; while, hardness is defined as the resistance that a solid offers against penetration or scratching. And 7068-T6511 is the most hard aluminum with tensile strength 710 Mpa. Tensile Testing and Hardness Testing of Various Metals ... percentage (42%) and a relatively low yield strength (31.84 ksi). If it is a tensile (stretching) force, the material experiences a tensile stress. Aluminum is, therefore, lighter than steel.
