As the key components of various wear solutions, carbide wear-resistant parts are crucial for the performance and durability of the final workpiece. However, there are various cemented carbides with different quality levels on the market,sometimes we found the prices of the same products differs a lot from different suppliers. How to judge the quality has become an important issue. The following content will introduce some methods to judge the quality of cemented carbide from a factory perspective

First of all, you should check the grade property and manufacturer information of cemented carbide. Qualified cemented carbide should have clear brand and manufacturer information, which proves that its production process is subject to strict quality control. By querying relevant standards and certification information, you can further understand the quality and reliability of the product.

Secondly, the specifications and appearance of cemented carbide wear-resistant parts need to be inspected strictly. The surface of finished products should be smooth and free of defects such as cracks and pitting, and the color should be uniform. If there are obvious flaws or uneven color, it probably means that the quality is substandard or inferior raw materials are used.

Next, physical performance testing can be performed. Common test items include hardness, wear resistance and corrosion resistance. The hardness test can be carried out by Rockwell hardness tester or Vickers hardness tester. Qualified carbide wear-resistant parts should reach the hardness corresponding to the brand to ensure its wear resistance and corrosion resistance.

In addition, usage testing is possible. By assembling the carbide products into the corresponding machinery, field use tests are carried out and the service life is recorded.
