The density of titanium and titanium alloys is only 4.51, which is smaller than steel and only half the weight of steel, but its strength is similar to that of ordinary carbon steel. Titanium belongs to the thermodynamically unstable metal and is very active. Titanium metal can form a natural oxide film (titanium dioxide) with the air. This stable, strong adhesion and excellent protective oxide film determines the corrosion resistance of titanium. Therefore, titanium has excellent corrosion resistance, followed by light texture, high tensile strength, and good mechanical properties are other outstanding characteristics of titanium alloys.
Titanium alloys can be divided into corrosion-resistant titanium alloys, structural titanium alloys, heat-resistant titanium alloys, and low-temperature titanium alloys.
The difference between titanium and stainless steel
1. It can be distinguished from the color. Titanium is a bit dark, revealing a cool color, which feels cool. Titanium is a bit darker than steel. The steel is white, pale. The two colors are very contrasting and can be seen.
2. It can also be distinguished by chemical methods, that is, soak it with nitric acid. Titanium does not react, and a strong reaction occurs when stainless steel is put down. The distinction between pure titanium and titanium alloy is difficult to see from the outside.
3. Titanium can make gray-black marks on ceramic tiles, but stainless steel can’t make marks.
4. Titanium has good corrosion resistance: it is easy to form a dense oxide film under 550℃, so it is not easy to be further oxidized. It has higher resistance to atmospheric, sea water, steam, and some acids, alkalis and soft media. Anti-loss thing.
5. Titanium has good thermal strength: Titanium alloy has a melting point of 1660°C, higher than iron, and has higher thermal strength. It can work below 550°C and exhibits better toughness at low temperatures.
6. Titanium processing is difficult: welding, electroplating, and cold drawing are very difficult. Welding and electroplating must be carried out in vacuum or under inert gas conditions (vacuum ion plating)
