Brinell hardness of steel alloy
WebNov 24, 2024 · The hardness is expressed as Brinell hardness number, and is obtained by dividing the load in kilograms, by the surface area of the indention in square millimeters. Brinell numbers for commonly used metals range from HB 15 to 750. Typical values include: Pure aluminum = 15. Mild steel = 120. WebBrinell hardness of Aluminium is approximately 240 MPa. The Vickers hardness test method was developed by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. The Vickers hardness test method can be also used as a microhardness test method, which is …
