Webster Hardness Testers for Copper Alloys W-B75b

Detailed Product Description

Introduction

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, in accordance with American Standard ASTM B647.

Suitable for testing on profiles, tubings and sheets. During the test no sampling is needed and it can not 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.

The standard hardness block is tested by the standard hardness testers, attached with inspection report.

Application

Used to check the effect of heat treatment and determine if

the mechanical property of the work piece is qualified.

Used to ascertain if the work piece is made and processed by

improper alloys.

Used for testing the work pieces with overlength,

overweight or assemblies inconvenient to be sent to the labs.

Used to distinguish the material hardness levels and to decide

the heat treatment state of materials such as annealed, 1/8 hard, 1/4 hard, 1/2 hard or full hard etc.
