While cobalt is harder than titanium, and therefore more scratch resistant, tungsten is still the hardest metal currently on the market. In simple terms, although cobalt and tungsten are both extremely hard metals, a tungsten ring will have a higher resistance to scratching. MONARCH-Tungsten Diamond Ring.
It also has high thermal conductivity with a range of twice that of tool steel and carbon steel. A high resistance to corrosion enables it to be used in extreme conditions in or out doors. It also has a very high modulus of elasticity. Tungsten carbide is the hardest metal known to man.
