Portable Brinell hardness tester / Model number MA70-IB
This device provides values that are close to those obtained from a standard Brinell hardness tester.
● Not only for test specimens, but also for any products or materials other than hollow thin-walled pipes, testing can be easily conducted regardless of size. ● The testing method is as follows: (1) Place the 5mm diameter steel ball at the tip of this device perpendicular to the surface of the test material, (2) Press the rounded part of this device with your hand, (3) Due to the internal mechanism, a constant force is applied to the steel ball, creating an indentation in the test material. (4) Measure the diameter of the indentation with the attached microscope and determine the Brinell hardness from the hardness table. ● In the case of steel, there is a nearly constant relationship between Brinell hardness and tensile strength, so tensile strength can also be estimated approximately using a separate table. * Manufactured according to the manufacturer's internal standards. * Not compliant with JIS. * The standard "hardness table" is for steel. * There is also an "aluminum hardness table," but it serves as a reference based on the manufacturer's experimental values.
