Copper Webster Durometer

W-B75/BB75 Series Webster Hardness Tester for copper alloys is a portable instrument which can perform on-site hardness testing on copper and copper alloys. By a quick and easy test, the hardness value can be read out directly with a simple clamp.

W－B75/BB75 is also suitable for testing on profiles, tubing and sheets. During the test no sampling is needed and it cannot damage the work pieces, especially suitable for a fast and nondestructive qualification inspection of the product hardness on the spot of production, sales and construction. 

W-B75 series Webster hardness tester is used for testing the hard brass and super-hard aluminum alloy materials.

W-BB75 series Webster hardness tester is used for testing annealed brass and red copper materials.

W - B75b, W - type BB75b instruments are special tubule instrument of W - B75 and W - type BB75, instrument anvil block is reduce to Ф5.8 mm, can test of over 6 mm inner diameter tube.

Indenter
