INNOVATEST Brinell Hardness Testers: Precision and Reliability
What is Brinell Hardness Testing?
Brinell Hardness Testing is a method used to determine the hardness of materials, particularly metals and alloys. This technique involves pressing a hard steel or carbide ball into the material's surface with a specific force and measuring the diameter of the indentation left behind. The Brinell hardness number (BHN or HBW) is calculated by dividing the load applied by the surface area of the indentation. This method is ideal for testing materials with coarse or uneven grain structures, such as cast iron and aluminum.
