W-20A韦氏硬度计是检验铝合金型材力学性能的首选仪器,符合中国有色标准YS/T420-2004和美国标准ASTM B647-84(2000).韦氏硬度计是一种可现场快速测试铝合金硬度的仪器。使用方便,一卡即可,硬度值直接读出,效率高,可靠性好。韦氏硬度计是以一定形状的硬钢压针,在标准弹簧试验力作用下压入试样表面,用压针的压入深度确定材 料硬度,定义0.01mm的压入深度为一个韦氏硬度单位。韦氏硬度单位表示为HW。
韦氏硬度计是小型便携式仪器,它体积小、重量轻、可单手操作,可快速、方便、无损地测试材料硬度,它不必取样,对操作技能要求不高,非常适于在生产现场对材料进行快速检测铝合金型材、管材、板材、铝零件及其他软金属的硬度。特别适于在生产现场、销售现场或施工现场对成批产品进行快速、非破坏性的逐件合格检查。韦氏硬度计还可用于测试紫铜、黄铜、软钢等材料的硬度。
W-20A韦氏硬度计是符合国家计量检定规程JJG944-201x《金属韦氏硬度计》 的产品。并且在销售之前经过第三方权威检测机构的检测,并每台仪器都附第三方检定证书。
仪器特点:
压针:进口特种钢材,新工艺制作成的压针,硬度高,耐磨性极佳。
指针:高强度的指针,长期使用或错误操作都不易弯曲变形。
表窗:高强度、高韧性的表窗玻璃,受到冲击后不易破裂。
手柄:锻造铝合金材料,阳极氧化的上手柄,美观、耐磨、耐污染。
硬度块:经标准硬度机检定的标准韦氏硬度块,附有检测报告。
高质量:精细的零件加工,精密的整机装配,严格的质量检验,保证了仪器的高质量。
稳定性好:满度点稳定,校正点稳定,指针无“爬行”。
换算方便:韦氏硬度值可换算成维氏、洛氏、布氏等硬度值。
