I. Purpose

Barcol hardness tester (Barcol hardness tester) is an indentation hardness tester. It is quick and easy to test the hardness of aluminum and aluminum alloy materials with one press.Aluminum alloy materials,Barcol hardness tester is mainly used to test the hardness of aluminum and aluminum alloys, and can also test the hardness of other soft metals and FRP products. It can test various super large, super wide and super thick workpieces and assemblies, and test plates, strips, profiles, forgings, castings, etc. W-20 Webster hardness tester is widely used in the aluminum processing industryW-20 , suitable for most aluminum alloys. For superhard aluminum alloys of 2024, 7075 and other grades, W-B75 Webster hardness tester or Barcol hardness tester can be used. Barcol hardness tester should be used for pure aluminum, low hardness aluminum alloy, particularly thick aluminum alloy and other aluminum alloy workpieces that are inconvenient to use Webster hardness tester. Barcol hardness tester is generally used as a supplement to Webster hardness tester and is used when testing pure aluminum, low hardness aluminum alloy and super large and super thick materials.

2. Features

Small size and light weight (510g), easy to carry. One-handed operation, no experience is required, and it can be tested in any occasion as long as it is within reach. The test range is wide. From very soft pure aluminum to very hard aluminum alloys can be tested, the effective test range is equivalent to Brinell hardness. 25～135HB. high sensitivity. The Webster hardness tester has only 20 graduations, while the Barcol hardness tester has 100 graduations for higher sensitivity. The Barcol hardness tester is only tested on one side of the sample without support, and is suitable for testing super-large and super-thick workpieces and assemblies. Conversion is convenient. Brinell, Rockwell, Vickers, Webster and other hardness values can be obtained through the conversion table.
