Newage Testing Instruments stocks a variety of Yamamoto test blocks for Rockwell, Brinell and Microhardness testing. Yamamoto hardness test blocks have less variation than other hardness blocks – as low as +0.1 HRC in the HRC 60 range. Each block is marked with the actual variation based on ten (10) tests. The 64mm diameter “TY” Rockwell blocks have twice the area of many competitive blocks so more tests can fit onto one block. The substantial thickness of the “TY” Rockwell blocks also prevent warping- sometimes a result of multiple indentations on a block. The additional thickness, combined with the highly parallel surface makes it possible to test with a standard anvil rather than a spot anvil.
