Rockwell Hardness Testing of PEEK Polymer Composites
PEEK (polyetheretherketone) is a high-performance composite material made by combining PEEK resin with reinforcing materials such as carbon fiber, glass fiber, and ceramics. PEEK materials with higher hardness have better resistance to scratching and abrasion, making them suitable for manufacturi...Read more -
Methods and Standards for Hardness Testing of Copper and Copper Alloys
The core mechanical properties of copper and copper alloys are directly reflected by the level of their hardness values, and the mechanical properties of a material determine its strength, wear resistance, and deformation resistance.There are usually the following test methods for detecting the h...Read more -
Selection of Rockwell Hardness Testing for Crankshaft Journals Crankshaft Rockwell Hardness Testers
The crankshaft journals (including main journals and connecting rod journals) are key components for transmitting engine power. In accordance with the requirements of the national standard GB/T 24595-2020, the hardness of the steel bars used for crankshafts must be strictly controlled after quenc...Read more -
Metallographic Sample Preparation Process of Aluminum and Aluminum Alloys and the Metallographic Sample Preparation Equipment
Aluminum and aluminum products are widely used in industrial production, and different application fields have significantly different requirements for the microstructure of aluminum products. For example, in the aerospace field, the AMS 2482 standard sets very clear requirements for grain size ...Read more -
International Standard for Hardness Testing Method of Steel Files: ISO 234-2:1982 Steel Files and Rasps
There are many types of steel files, including fitter’s files, saw files, shaping files, special-shaped files, watchmaker’s files, special watchmaker’s files, and wood files. Their hardness testing methods mainly comply with the international standard ISO 234-2:1982 Steel Files ...Read more -
The Role of Clamps for Vickers Hardness Tester and Micro Vickers hardness Tester (How to Test the Hardness of Tiny Parts?)
During the use of Vickers hardness tester /micro Vickers hardness tester, when testing workpieces (especially thin and small workpieces), incorrect test methods can easily lead to large errors in the test results. In such cases, we need to observe the following conditions during workpiece test: 1...Read more -

How to choose a suitable hardness tester for carbon steel round bars
When testing the hardness of carbon steel round bars with lower hardness, we should choose a hardness tester reasonably to ensure that the test results are accurate and effective. We can consider using the HRB scale of the Rockwell hardness tester. The HRB scale of the Rockwell hardness tester u...Read more -
Connector terminal inspection, terminal crimping shape sample preparation, metallographic microscope inspection
The standard requires whether the crimping shape of the connector terminal is qualified. The porosity of the terminal crimping wire refers to the ratio of the uncontacted area of the connecting part in the crimping terminal to the total area, which is an important parameter affecting the safet...Read more -
40Cr, 40 chromium Rockwell hardness test method
After quenching and tempering, chromium has excellent mechanical properties and good hardenability, which makes it often used in the manufacture of high-strength fasteners, bearings, gears, and camshafts. Mechanical properties and hardness testing are very necessary for quenched and tempered 40Cr...Read more
