Hardness Test Methods for Aluminum Hardness. Here are some of the most common hardness tests used in the industry to ascertain the hardness of Aluminum. Brinell Hardness Test. This test uses an indenter with huge loads making it suitable for very thick, large, and rough-grained material surfaces.
Vickers hardness with very small load, the load is 5-200gf. Indicated by Hm, it can be used to test the hardness of single grain or phase. Vickers hardness test
The Vickers hardness test is a widely used standard test method for measuring the hardness of metals. It measures the ability of a material to withstand penetration by an indenter when it is pressed with a fixed load. You can also use it to measure the indentation hardness of non-metallic materials, provided they are sufficiently dense.
Hardness testing in the low-load range applies when the test load falls between an interval of 0.2 kgf and 5 kgf (test load ≥ 0.2 kgf and < 5 kgf). The most commonly used low-load method is Vickers. Low-load hardness testing is mainly used for testing of small parts, thick coatings and materials with low hardness. For the Vickers hardness test, a square base pyramid with a opening angle of 136° is used as the indenter (opening angle = angle between two opposite surfaces of the pyramid). The angle was chosen so that the Vickers hardness values are comparable to a certain degree with the Brinell hardness values (applies to approx. 400 HBW or 400 HV). The .

Application of Load. The Vickers hardness tester applies a precisely controlled load to a diamond indenter, typically in the range of a few kilograms-force to several tens of kilograms-force. . Vickers hardness testing is extensively used in the metals and alloys industry to evaluate different metallic materials' hardness, strength, and . 3. Vickers Hardness (HV) Vickers hardness is determined by pressing a diamond square cone with a 136° top angle and a load of up to 120kg into the material’s surface. The Vickers hardness value (HV) is calculated by dividing the load by the surface area of the indentation pit, expressed in kgf/mm². 4. Leeb Hardness (HLD) The hardness testing load is the load (“force”) that is applied to the indenter when pressing into the material being tested. .
