Many manufacturers friends in the purchase of beryllium copper beryllium copper hardness, it was found there are a lot of specifications, such as HRC, HRB, HB, HV and so often dazzling. Run beryllium copper factory in Guangdong and small series and your tidy beryllium copper hardness specifications. More common beryllium copper Rockwell hardness units, is the ruler of the usual HRC, HRB and HRF. HRC scale range is 20 ~ 70HRC; HRB scale range is 20 ~ 100HRB; conversion relation: 100HRB≈20HRC. HRF scale range is 60 ~ 100HRF, HRF scale is used abroad more. Vickers hardness, code: HV, it is suitable for large workpiece and the deeper surface layer hardness measurement. Brinell hardness, the unit is HBW, detection range: the range of 8 ~ 650HBW, high-precision Lintong order, Brinell hardness measurement principle is to use a certain size the test force F (N), to buy high-precision Lintong, the diameter D (mm) of hardened steel ball or carbide ball is pressed into the surface of the metal tested, high-precision phosphor bronze with price, holding a predetermined time after removing the test force, with a reading microscope measure indentation average diameter d (mm), and then calculated according to the formula HB Brinell hardness value or HB hardness value according to the table, isolated from the prepared Brinell d.
