WebAluminum "Hardening" - How it works? The term “ heat treating ” for aluminum alloys is frequently restricted to the specific operations employed to increase strength and hardness of the precipitation-hardenable wrought and cast alloys. These usually are referred to as the “heat-treatable” alloys to distinguish them from those alloys in which no significant … WebDuring this Brinell hardness test, you’ll require a carbide ball indenter having a diameter ranging from 1 to 10mm. The indentation resulting from the application of this indenter is often very deep as it uses a huge load that goes from 1 to 3,000kgf. This large load makes this test suitable for brass samples with large areas and rough surfaces.
