Hardness Testing Services
Applied Technical Services’ metallurgy lab offers various hardness testing services. We provide prompt and professional litigation support, material identification, failure analysis, and other metallurgical services.
What is Hardness Testing, and What is its Importance
A material’s hardness is its resistance to permanent indentation, and hardness testing identifies the physical properties of a material, including strength, wear resistance, and ductility.
A material’s strength and durability heavily determine its potential uses and applications, and hardness testing is a valuable tool in evaluating a material’s resistance value. Hardness testing is helpful in failure analysis, quality control, and materials testing services.
Brinell Hardness Test
The Brinell hardness test determines a metal’s hardness by measuring the diameter of the indention left by an indenter. The test is commonly conducted on metals with rough surfaces and has various advantages, including:
- Quick
- Applicable to light and heavy metals
- Results are easy to measure
- Useful for irregular surfaces
Knoop Hardness Test
The Knoop hardness test measures a material’s hardness by applying a diamond or pyramid-shaped indenter to test the material. Technicians remove the indenter and measure the indention’s size to determine the material’s hardness value. The test has several advantages, including:
- Ideal for brittle and sensitive materials
- Applicable to all materials; soft or hard
- Highly accurate
- Minimal damage done when testing
- Useful for irregular surfaces
Vickers Hardness Test
The Vickers hardness test measures an indentation’s depth and converts it into a material’s hardness value.
- Applicable to all materials; soft or hard
- Minimal damage done when testing
- Only requires a single type of indenter
- Highly accurate
Rockwell Hardness Test
The Rockwell hardness test determines a material’s hardness by converting the depth of an indentation into a hardness value.
- Quick
- No preparation needed
- Minimal damage testing
- Inexpensive
