1. High-quality Men's tungsten carbide rings wear-resistant, scratching, high-temperature resistance Tungsten carbide is the second hardest metal in the world and its hardness is just lower than diamonds. The tungsten content of tungsten carbide used to make men's rings should be above 80%, and the golden ratio is 85.7%, which is also known as 857 tungsten carbide. This content of the men's tungsten carbide rings is not afraid of grinding, the knife does not spend (except professional tools), is not afraid of high-temperature forging, the property is very stable. But don't fall heavily, don't get the ground to grind, because the cement contains artificial silicon, this thing is harder than diamonds. 2. High-quality men's tungsten carbide rings is very bright, slightly black The polished men's tungsten carbide rings exudes a dazzling luster and shines on the fingers. Careful observation, men's tungsten carbide rings, and some other men's metal rings still have some differences. The men's tungsten carbide rings is restrained and slightly black, and the other men's metal rings are slightly floating compared to the men's tungsten carbide rings, while the men's tungsten carbide rings feels more stable due to its unique metallic surface.
