Handheld Portable W-20 Webster Hardness Tester

Aluminum Alloy Brass Stainless Steel Red Copper Tester

Product Overview

The Handheld Portable W-20 Webster Hardness Tester is designed for rapid on-site hardness testing of aluminum alloys, brass, stainless steel, and red copper. This compact, lightweight instrument provides quick, non-destructive testing with direct hardness value reading.

Key Applications

Testing hardness of aluminum alloy profiles, pipes, plates, and workpieces
Rapid conformity inspection at production, sales, or construction sites
Testing copper, brass, mild steel, and other soft metals
Compliant with Chinese non-ferrous standard YS/T420-2004 and American standard ASTM B647-84 (2000)

Performance Features

Indenter: Made with new materials and processes for high hardness, long life, and excellent interchangeability
Pointer: High-strength design resistant to bending and deformation
Window: High-strength, tough glass for durability
Handle: Forged material with anodized surface for beauty, wear resistance, and contamination protection
Hardness Block: Standard hardness block tested by standard hardness machine with test report
Quality: Precision parts processing, accurate assembly, and strict quality inspection
Stability: Stable full-scale and calibration points with no pointer "crawling"
Conversion: Webster hardness values convertible to Vickers, Rockwell, Brinell and other hardness values

Frequently Asked Questions

What is Webster Hardness tester?

The WEBSTER Hardness Testers are portable instruments that can perform on-site hardness testing on aluminium alloys, brass, copper and soft steel. A quick and easy test, the hardness value can be read out directly from the indicator with a simple clamp.

What is the best hardness tester?

The Rockwell method is the most universal because it uses both a penetrating diamond cone and a penetrating steel ball to measure the hardness of a material. The diamond cone can only be used on hardened steel and hard metals. It is not recommended below 785 N/mm² hardness.

How accurate is hardness testing?

A study demonstrated that the effect on the HRC scale indicated a tilt angle of one degree between the specimen surface and the indenter's axis could result in a 5% error in hardness. Tilt angle should never surpass 2 degrees to guarantee accurate testing.

How do you test the hardness of aluminum?

The most common type of hardness test is the Rockwell test. The Rockwell test encompasses a set of tests for different hardness ranges. The Rockwell B (HRB) scale is used for aluminum and structural steels (softer materials) while the Rockwell C (HRC) scale is used for high carbon alloy steels (harder metals).

How accurate are portable hardness testers?

By comparing the portable hardness testers, it was found that the hardness tester TH170 was more accurate for Brinell hardness test (inaccuracy -3.90 %), Rockwell hardness test (-4.81 %) and Leeb hardness test (+0.38 %); the hardness tester TH1100 was more accurate only for Vickers hardness test (-1.75 %).
