FAQ's
What is the use of Webster Hardness Tester?
▼
The Webster Hardness Tester is used to measure the hardness of soft metals like aluminum alloys, brass, and copper. It offers instant readings on the spot, making it ideal for fast and non-destructive quality control.
How is Webster Hardness measured?
▼
Webster Hardness is measured by manually pressing the tester handles like pliers onto the sample. The indenter penetrates the surface, and the dial gauge shows the hardness reading immediately. No preparation or cutting of the sample is required.
What materials can be tested using the Webster Hardness Tester?
▼
It is best suited for soft metals such as aluminum alloys (1000–7000 series), brass, copper, and mild sheet metals. It is not recommended for very hard or ferrous materials.
What industries use Webster Hardness Testers?
▼
Webster testers are widely used in industries such as:
- Aluminum extrusion and fabrication
- Aerospace and aviation
- Automotive and transport
- HVAC manufacturing
- Quality assurance and material inspection

Can I use the Webster Hardness Tester for testing soft materials?
▼
Yes, the Webster Tester is specifically designed for testing soft materials such as aluminum, brass, and copper. It is not suitable for rubber, plastics, or hardened steel.
What is the typical range of hardness for the Webster Hardness Tester?
▼
The Webster scale typically measures hardness in the range of 0 to 20 HW (Webster Hardness units), which corresponds approximately to 20–110 HRE on the Rockwell scale for aluminum alloys.
What is the weight of the Webster Hardness Tester?
▼
The typical weight of the Webster Hardness Tester (including case and accessories) is around 0.5 kg, making it lightweight and portable for on-site applications.
