Product Description
The SW-20 Series Digital Webster Hardness Tester is a lightweight and portable instrument specifically designed for rapid hardness testing of aluminum alloy materials. Also known as a clamp-type hardness tester, it provides quick and direct hardness readings with a single press. The instrument complies with Chinese nonferrous standard YS/T420 and American standard ASTM B647, making it one of the two recommended testers in YS/T420. It is suitable for aluminum alloy profiles, pipes, and plates, especially for on-site inspection in production, sales, and engineering applications. Its digital display ensures clear, accurate readings, meeting the needs of fast and nondestructive hardness evaluation.
Product Advantages
Suitable for rapid, nondestructive hardness testing of aluminum alloy profiles, tubes, and sheets on production lines, sales sites, and construction sites.
Provides fast and direct digital display of hardness values.
Webster hardness values can be converted into Vickers, Rockwell, Brinell hardness and tensile strength values.
Application Range
Inspect heat treatment effectiveness
Determine improper alloy processing
Measure extra-long or heavy components not suitable for lab testing
Used for production inspection, acceptance inspection, and quality supervision
Suitable for hardness testing of aluminum alloys (1100–7075 series)
