Hardness Testing of Thick Aluminum Profiles and Bars

Dec 28 , 2021

In aluminum production, it is inevitable that the profile is thick or the diameter of aluminum rod is large. The opening size of W-20 Webster hardness tester is 6mm and that of w-20a Webster hardness tester is 13mm. There should be no problem in measuring hollow aluminum pipe, but not for solid aluminum rod with diameter more than 13mm. In this case, it is necessary to measure the hardness of profile with Babbitt hardness tester. As long as one side contacts the sample, the Babbitt hardness tester is suitable for measuring ultra large, ultra wide and ultra thick materials.

The Barcol hardness tester is also very convenient to use. Just hold the instrument with one hand and press it down with force. The Barcol hardness tester has 100 scales, which is more sensitive than Webster hardness. The effective range of measurement is equivalent to Brinell hardness of 25 ~ 150hbw. It can be used from pure aluminum to super hard aluminum alloy. The interchangeability of Babbitt hardness value is also very good, which can be directly converted into Webster, Brinell, Rockwell, Vickers and other hardness values.
