How to Identify Genuine Tungsten Carbide

In fields such as metal processing, Tungsten Carbide is widely favored for its excellent properties. However, the market is flooded with genuine and counterfeit Tungsten Carbide products. This article will introduce methods for identifying genuine Tungsten Carbide from multiple aspects.

Firstly, it’s essential to understand the basics of Tungsten Carbide. Made from tungsten carbide (WC) and cobalt (Co) metal powders, its hardness and wear resistance depend on the tungsten carbide content, while cobalt serves as the binding phase. High-quality Tungsten Carbide should possess high hardness, wear resistance, and toughness.

Secondly, observe the appearance and texture of Tungsten Carbide. Genuine Tungsten Carbide exhibits a uniform dark gray or black color with a high surface gloss. Its texture is clear and even, without pores, cracks, or inclusions. The cross-section reveals evenly distributed tungsten carbide particles tightly wrapped by cobalt.

Next, conduct performance tests. Hardness is a key measure of Tungsten Carbide’s performance; high-quality products should have a hardness between 86 and 93 HRA. Wear resistance tests observe the amount and morphology of wear; genuine products show low wear and good morphology. Toughness tests assess fracture behavior and toughness values; genuine products have high toughness.

Furthermore, checking labels and certificates is crucial. High-quality Tungsten Carbide products will have clear labels and batch numbers, along with quality certificates and test reports. Purchase from reputable channels and beware of products with excessively low or high prices.

In summary, identifying genuine Tungsten Carbide requires consideration of multiple factors. Understand the basics, observe appearance and texture, conduct performance tests, check labels and certificates, purchase from reputable channels, and consider pricing. Only then can you select truly high-quality Tungsten Carbide products.
