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, Brinell hardness measurement principle is to use a certain size the test force F (N), the diameter D (mm) of hardened steel ball or hard After the ball is pressed into the surface of the alloy metals tested, holding a predetermined time removable test force, with a reading microscope measure indentation average diameter d (mm), and then calculated according to the formula HB Brinell hardness value or have been prepared in accordance with d from Good Brinell hardness HB find value in the table. Run beryllium copper factory in Guangdong and finishing, buy insulation Nickel Silver, For more information, please contact us, please indicate the source. Lintong perform standard Executive standard * GB GB / T5231 (processing of copper and copper alloy chemical composition and shape of the product); * Japanese standard: JIS H3110, JIS H3130 (phosphor bronze and zinc white copper strip Standard); * American Standard: ASTM B 103 / B 103M (phosphor bronze plate and strip standard); * GB / T2059 copper and copper alloy strip; * GB / T17793 general-purpose processing of copper and copper alloy strip material dimensions and tolerances. Characteristics Characteristics phosphor has a higher corrosion resistance, wear resistance, high yield strength, fatigue strength, sparks do not occur out of the elastic properties and excellent bending formability.
