1. Product introduction:

WebestrtTWH (B, B75, BB75) Webster hardness tester (clamp hardness tester) is an indispensable instrument for aluminum alloy profiles, aluminum alloy doors and windows, aluminum processing industries, and aluminum product companies. The instrument is used in aluminum alloy production and aluminum profile production. , Aluminum profile doors and windows production, glass curtain wall production has been widely used.
* Determine whether the workpiece has heat treatment, check the heat treatment effect, and determine whether the mechanical properties of the material are qualified.
* Determine whether the workpiece is processed from an inappropriate alloy, and determine whether the alloy composition of the material is qualified.
* To test long and heavy workpieces or assemblies that are inconvenient to send to the laboratory.

* Used for production inspection, acceptance inspection and quality supervision inspection.

Type B is mainly used for hardness measurement of aluminum and aluminum alloys (series 1100-7075). It can also be used to measure the hardness of some steel and copper alloys. The measurement range is:
aluminum and aluminum alloy HRE 24-110
steel HRB 10-98
copper alloy HRF 60-90
B—75 type is mainly used to measure steel and harder Alloys (series 2024, 6061 and 7075), copper alloys from annealed state to fully hardened state, the range is:
steel: HRB 20-100
copper alloy: HRF 15-90
aluminum alloy: HRE 83—113
BB— Type 75 is mainly used to measure electrolytic copper and copper with lower hardness. At the same time, it can be used to measure other similar materials, and its range is:
Copper: HRE 18-100

2. Features

* Small size, light weight, can be operated with one hand, easy to carry.
* Can measure a variety of shapes.
* The operation is simple, and the operation skills have no influence on the reading.
* The measured value can be converted into the commonly used Vickers (HV), Rockwell (HRF, HRE) hardness value or tensile strength (σb) value by looking up the table.
