W-20 Aluminium Webster Hardness Tester
An instrument that can quickly test the hardness of aluminum alloys in the field. The Webster hardness tester is easy to use, just one card, the hardness value can be read directly, high efficiency and good reliability.
Used to quickly test the hardness of aluminum alloy profiles, pipes, plates, aluminum workpieces and other soft metals. It is particularly suitable for fast, non-destructive piece-by-piece qualification inspections on batches of products at production, sales or construction sites.
The Wechsler hardness tester is the first choice for testing the mechanical properties of aluminum alloy profiles. It conforms to the Chinese nonferrous standard YS / T420-2004 and the American standard ASTM B647-84 (2000).
The Webster hardness tester can also be used to test copper, brass, mild steel, etc.
Note: The picture shows the electroplating treatment, and it can also be oxidized! !!
