W-20B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-20B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。
韦氏硬度计主要用于:确定工件有无热处理,检查热处理效果。确定工件是否为不适当的合金加工而成。测试不便送到实验室的过长、过重工件或装配件。用于生产检验、验收检验和质量监督检验。换算成常用的维氏、洛氏、布氏硬度及抗拉强度值.
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。

Selection FAQ

Can the configuration of W-20B be adapted to my application?

Yes. Beyond the standard configuration, measuring range, fixtures, optics and software functions can be adapted. Send your sample and test requirements and our engineers will return a configuration list and quotation.

Can I test my samples before ordering?

Yes. Samples can be mailed to our Shanghai Fengxian laboratory for free testing with a written report, or you can book an on-site demonstration to confirm the workflow and data format.

How are lead time, installation and after-sales service handled?

Standard configurations usually ship within 15-30 working days, including first installation, commissioning and operator training. The instrument carries a one-year warranty and software upgrades are free for life.

General information only — final configuration and applicable conditions are subject to the mutually confirmed technical document.
