Brinell Micro Electronic Hardness Tester Machine Vickers Hardness 4900 N
1. Brief Introduction Hardness is one of the mechanical properties of most importance in a material’s performance, and the hardness test is an essential measure to determine the quality of a metallic material or a part made from the material. Hardness is the ability of a material to resist, under certain conditions, the pressure from another solid body which will not carry any residual deformation. The more the ability means the higher the hardness, and vice versa. Brinell testing is mainly used in hardness determination for metallic materials such as cast iron, steel profiles, nonferrous metals and soft alloys, and also can be used for testing of hard plastics, bakelite and some other nonmetallic materials. It is suitable for using in factories, workshops, laboratories, universities and research institutes. 2. Technical Specifications
