product description:
Webestrt\TWH (B, B75, BB75) Webster Hardness Tester (clamp type Hardness Tester) is an instrument required by aluminum alloy profiles, aluminum alloy doors and windows, aluminum processing industry, and aluminum product enterprises. It has been widely used in production, aluminum profile doors and windows production, and glass curtain wall production.
* 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.
*Test parts or assemblies that are too long or too heavy to be sent to the lab.
*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). can also be used
Measures the hardness of certain steel and copper alloys in the following ranges:
Aluminum and aluminum alloy HRE24-110
Steel HRB10-98
Copper alloy HRF60-90
Type B-75 is mainly used to measure steel and harder alloys (series 2024, 6061 and 7075), and copper alloys from the annealed state to the full hard state, and its range is:
Steel: HRB20-100
Copper alloy: HRF15-90
Aluminum alloy: HRE83—113
BB-75 type 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, the range is: Copper: HRE18-100
Features:
*Small size, light weight, can be operated with one hand, easy to carry. *Can measure various shapes.
*Easy to operate, operation skill has no effect on the reading.
*The measured value can be converted into commonly used Vickers (HV), Rockwell (HRF, HRE) hardness values or tensile strength (σb) values by looking up the table.
Basic configuration: main machine, standard hardness block, instrument box, spare indenter
