Description

AZA 1011 Rockwell Hardness Tester: Rapid and Precise Hardness Determination by Azalab

The Azalab AZA 1011 Rockwell Hardness Tester is a widely utilized and highly efficient instrument designed for the rapid and accurate determination of the Rockwell hardness of a broad spectrum of metallic materials, including steel, cast iron, aluminum, brass, and hardened alloys. The Rockwell hardness test is a popular method due to its speed, simplicity, and direct-reading capabilities, making it indispensable for quality control, material inspection, heat treatment verification, and research in manufacturing industries across India and globally. The AZA 1011 provides a reliable benchtop solution for consistent and repeatable hardness measurements.

Understanding Rockwell Hardness Testing with the AZA 1011 Rockwell Hardness Tester

The Rockwell hardness test measures the net increase in depth of a permanent indentation caused by a major load being applied and then removed, while a minor load is still applied. The process involves two stages:

1. Minor Load Application: A small preliminary (minor) load (e.g., 10 kgf) is applied to the indenter, which penetrates the material surface and ensures good contact, eliminating errors from surface irregularities. This establishes a zero reference depth.
2. Major Load Application: A much larger (major) load (e.g., 60 kgf, 100 kgf, or 150 kgf) is then applied, causing deeper penetration. After a specific dwell time, this major load is removed, but the minor load remains.
3. Depth Measurement: The Rockwell hardness number is inversely proportional to the additional depth of penetration that occurred under the major load. This measurement is automatically converted to a Rockwell hardness value and directly displayed on the machine’s dial or digital screen.

The AZA 1011 Rockwell Hardness Tester is designed to execute this sequence precisely and consistently, providing an accurate, direct reading of the hardness number. This method is particularly valued for:

• Speed and Efficiency: It’s one of the fastest hardness testing methods, making it ideal for high-volume quality control.
• Direct Reading: The hardness value is read directly from the machine, eliminating the need for optical measurement of indentation diameter and calculations, unlike Brinell.
• Non-Destructive (Relatively): The indentation is relatively small, often allowing the tested part to be used in service if the test location is not critical.
• Versatility: With different loads and indenters, it can cover a wide range of material hardnesses.
