Best Answer: So used to something it doesn't impress you anymore. Unimpressed, unfazed. A person who is blasÃ© about something would respond Meh.
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.
Tungsten and its alloys are widely used for filaments in older style (not energy saving) electric bulbs and electronic tubes. It is used for making heavy metal alloys because of its hardness. Tungsten is used for high-temperature applications such as welding. High speed steel (which can cut material at higher speeds than carbon steel), contains up to 18% tungsten. Tungsten carbide (WC or W 2 C) is extremely hard and is used to make drills.
