How to choose the right hardness testing equipment?

Use Leeb testers for large or heavy metal parts. Use Webster testers for thin-walled materials like aluminum tubes or sheets. Select impact devices based on the specific application area.

Product Q&A

Q:What is the thinnest thickness a Leeb Hardness Tester can measure?

For D-type impact devices, the minimum thickness is 25mm. If coupled to a solid support, the minimum thickness is 3mm. Small and thin parts must be coupled to a solid support for testing.

Q:What is the meaning of hardness?

Hardness defines a material's resistance to deformation, scratching, or indentation. Leeb testers use rebound hardness (elasticity), while others use indentation or scratch methods.

Q:How to measure hardness by Leeb Hardness Tester?

The tester calculates hardness from the energy loss of an impact body. The impact body accelerates, impacts the surface, and rebounds. The ratio of rebound velocity to impact velocity determines the Leeb Hardness Unit (HL).

Q:What are the applications of Leeb Hardness Tester?

It is used for measuring die cavities, bearings, heavy workpieces, installed machinery, and detecting surface hardness in hollow spaces. It works on ferrous and non-ferrous materials.

Q:What are the advantages of Leeb Hardness Tester?

It is compact, lightweight, and portable. It allows on-site testing without moving samples. It uses digital signal processing and can detect impact device types at any angle.
