Though loads of 500, 1000, 1500, 2000, 2500, and 3000 N are available in a typical Brinell hardness tester, a load of 500 N is used for testing relatively soft metals such as copper and aluminium alloys, while the 3000 N load is often used for testing harder materials such as steels and cast irons.However, the general rule is that the combination of test load and ball diameter .These approximate relationships between hardness and tensile strength do not apply to nonferrous metals, with the possible exception of certain aluminum alloys. Related: Brinell Hardness Testing Equation. Table A Brinell Hardness to . The Brinell hardness test is ideal for measuring the hardness of metals with coarse or inhomogeneous grain structures, such as cast iron and softer metals like aluminum alloys. It measures the diameter of a larger indentation, which averages out variations in the material’s microstructure, providing a more representative hardness value for . General Information about the Brinell Hardness Test. The Brinell hardness test involves pressing a hard ball indenter, usually made of tungsten carbide, into the material’s surface with a specified force. The diameter of the ball is typically 10 mm, but smaller diameters such as 2.5 mm can also be used for specific applications.
The Brinell hardness test records the diameter and depth of the indentation caused by a ball-shaped indenter, with the indenter pressed into a material's surface. This is the guide on how to read and represent brinell hardness values. . The hardness number for pure aluminum is fifteen, while the hardness number for hardened aluminum is .
Prosedur Hardness Test : 1. Brinell Hardness Test. Hal yang perlu diperhatikan pada saat pengujian hardness Brinell adalah sebagai berikut : Spesimen harus memenuhi persyaratan : – Rata dan halus. – Ketebalan minimal 6 mm. – Bisa ditumpu dengan baik dan permukaan uji harus horizontal. These heat-treated samples were then tested mechanically using the Brinell hardness test (BH). . Aluminum Matrix Composites (AMC) are frequently employed to meet industrial requirements. In this .The Brinell hardness test method as used to determine Brinell hardness, is defined in ASTM E10. Most commonly it is used to test materials that have a structure that is too coarse or that have a surface that is too rough to be tested using another test method, e.g., castings and forgings. Brinell testing often use a very high test load (3000 .

Aluminum alloys are generally softer than other metals, such as steel or titanium. However, the hardness of aluminum alloys can vary widely depending on the alloying elements present and the heat treatment process used. The following tables provide a list of Brinell hardness (HB) values for common aluminum alloys. When the Brinell hardness test cannot be used, such as when the material’s HB value is greater than 450 or the sample size is too small, the Rockwell hardness test is used instead. This test involves pressing either a diamond cone with a top angle of 120° or a steel ball with a diameter of 1.59 mm or 3.18 mm into the surface of the tested . The article covers data on the Brinell hardness of the forged precipitation-hardened aluminum alloy EN AW-2618A in the initial T61 condition (i. e. slightly underaged) and after isothermal aging for up to 25,000 h at aging temperatures between 160 °C and 350 °C.

Although this standard specifies the unit of force in the International System of Units (SI) as the Newton (N), because of the historical precedent and continued common usage of kgf units, force values in kgf units are provided for information . The Brinell hardness test consists of applying a constant load or force, usually between 187.5 and 3000Kgf, for a specified time (from 10 – 30 seconds) typically using a 2.5 or 10mm diameter tungsten carbide ball (see schematic in the image to your right – Figure 23.3). .
