1. High strength

The density of titanium alloy is generally about 4.51g/ cubic centimeter, only 60% of steel, the density of pure titanium is close to the density of ordinary steel, and some high-strength titanium alloys exceed the strength of many alloy structural steel.

2. High chemical activity

Titanium has a large chemical activity and produces a strong chemical reaction with O, N, H, CO, CO2, water vapor, ammonia and so on in the atmosphere.


3. Good corrosion resistance

Titanium alloy works in humid atmosphere and seawater medium, its corrosion resistance is much better than stainless steel; Resistance to pitting corrosion, acid corrosion, stress corrosion is particularly strong; Excellent corrosion resistance to alkali, chloride, chlorine, nitric acid, sulfuric acid, etc.


4. Low temperature resistance

Titanium alloy can still maintain its mechanical properties at low and ultra-low temperatures. Titanium alloys with good low temperature performance and very low gap elements, such as TA7, can maintain a certain plasticity at -253 ° C.


5. High heat intensity

The use temperature of titanium is several hundred degrees higher than that of aluminum alloy, and it can still maintain the required strength at a moderate temperature. It can work for a long time at a temperature of 450~500 ° C. These two types of titanium alloys still have a high specific strength in the range of 150C~500 ° C, and the specific strength of aluminum alloy decreases significantly at 150 ° C. The operating temperature of titanium alloy can reach 500℃, and that of aluminum alloy is below 200℃.


6. Low thermal conductivity elasticity

The thermal conductivity of titanium =1524W/(mK) is about 1/4 of nickel, 1/5 of iron, 1/14 of aluminum,

The thermal conductivity of various titanium alloys is about 50% lower than that of titanium.
