Core Tip: What is the best material for casting dentures? If you’re talking about pure titanium, of course pure titanium is better than cobalt-chromium alloys. If we are talking about titanium alloys, cobalt-chromium alloys are better than titanium alloys. Although titanium alloys are theoretically better than cobalt-chromium alloys, due to the limited casting technology in China, most of the casting process… If you are talking about pure titanium, of course pure titanium is better than cobalt-chromium alloys. If we are talking about titanium alloys, cobalt-chromium alloys are better than titanium alloys. Although titanium alloys are theoretically better than cobalt-chromium alloys, due to the limited casting technology in China, most of the titanium will be lost during the casting process, and the superiority of titanium alloys will be lost, so if you choose between the two, it is recommended to choose Cobalt-chromium alloy
