W-20 series aluminum alloy VickersHardness tester(also known as clamp type)Hardness tester）, is a lightweight instrument that can quickly test the hardness of aluminum alloys on site, and can measureOther InstrumentsAppearance that cannot or is inconvenient to measure, such as extruded profiles, pipes, plates, etc. The measurement process causes no damage to the workpiece and does not require sampling. Specially suitable for rapid non-destructive hardness testing of products at production, sales, or construction sites. The testing is fast, simple, and easy. The hardness value can be directly read out, which complies with the Chinese non-ferrous standard YS/T420 and the American standard ASTM B647. It is one of the two recommended instruments for YS/T420. This instrument has been applied in most domestic aluminum profile factories, many door and window curtain wall enterprises, aluminum material users, and engineering quality inspection and technical supervision departments.

Quasi hardness blockAfter testing by a quasi hardness machine, a testing report is attached.

The Vickers hardness value can be converted into commonly used Vickers, Rockwell, Brinell hardness and tensile strength values.

Purpose:

*Determine whether the workpiece has undergone heat treatment and check the heat treatment effect.

*Determine whether the workpiece is machined from an inappropriate alloy.

*Testing of excessively long or heavy workpieces or equipment that are difficult to deliver to the laboratoryaccessory.

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

Main features:
1. Small size, light weight, can be operated with one hand, easy to carry.
2. Can measure various shapes.
3. Easy to operate, operational skills have no impact on readings.
4. Easy to read and convert to other hardness values.
