The hardness of tungsten carbide is only inferior to that of slightly diamond, and the Mohs hardness is about 8~9M. Diamonds are indeed the most Mohs hardness in the world, and no other material can leave scratches on the surface of the diamond unless the diamond is diamondd.Click to see full answer. Accordingly, which is harder tungsten carbide or diamond?Tungsten is rated at about a 9 on the Mohs scale of hardness. A diamond, which is the hardest substance on earth, is rated at a 10. Tungsten carbide is about 2 or 3 times harder than titanium and cobalt chrome.Also, what is stronger than tungsten carbide? Hardness – Both titanium and tungsten carbide are considerably harder than precious metals like gold and platinum. However, tungsten carbide is one of the hardest materials in existence and substantially harder than titanium, registering a 9 on the Mohs scale of mineral hardness (compared to titanium’s score of 6). Likewise, people ask, is there anything harder than a diamond? Scientists have calculated that wurtzite boron nitride and lonsdaleite (hexagonal diamond) both have greater indentation strengths than diamond. Source: English Wikipedia. (PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world.Can tungsten carbide cut diamond?But since many folks equate tungsten with the very hard carbide form: no, tungsten carbide is not usually able to scratch or cut diamond. Now, tungsten carbide is durable enough that it could probably help grind or cut diamond.
