The Magic of Titanium's Color Changes

          Titanium is stable in air at room temperature. It only undergoes its "colorful" changes when heated to high temperatures. This is mainly because when titanium is heated in air, it reacts with oxygen to form a dense oxide film. This oxide film not only protects the titanium surface but is also the fundamental source of its color changes. According to relevant research, titanium heated to 200℃ is silvery-white, 300℃ is pale yellow, 400℃ is golden yellow, 500℃ is blue, 600℃ is purple, 700℃-800℃ is grayish-red, and 900℃ is gray—a truly vibrant array of colors. If the titanium products you purchase on TZZRACING change color, it means you have purchased genuine titanium. We hope you can find your own DIY colored exhaust pipe on our website. Special Note: Polishing and cleaning titanium before heating determines the luster and brightness of the heated color.
