1. Characteristics of titanium rods

l High strength. The density of titanium alloy is generally about 4.51g / cm3, which is only 60% of steel. The density of pure titanium is close to that of ordinary steel. Some high-strength titanium alloys exceed the strength of many alloy structural steel.

lHigh thermal strength, the operating temperature is several hundred degrees higher than that of aluminum alloy, and it can still maintain the required strength at medium temperature. It can work for a long time at the temperature of 450 ～ 500 ℃. There is still a high specific strength, and the specific strength of aluminum alloys decreases significantly at 150 ° C. The working temperature of titanium alloy can reach 500 ℃, while that of aluminum alloy is below 200 ℃.

l Good corrosion resistance. Titanium alloy works in humid atmosphere and seawater media, and its corrosion resistance is much better than stainless steel. It is particularly resistant to pitting, acid, and stress corrosion. It is resistant to alkali, chloride, and chlorine. Organic goods, nitric acid, sulfuric acid, etc. have excellent corrosion resistance. However, titanium has poor resistance to reducing oxygen and chromium salt media.

l Good low temperature performance, titanium alloy can still maintain its mechanical properties at low temperature and ultra low temperature. Low temperature properties, titanium alloys with very low interstitial elements, such as TA7, can still maintain a certain degree of plasticity at -253 ° C. Therefore, titanium alloy is also an important low temperature structural material.

lThe chemical activity is large, the chemical activity of titanium is large, and it has a strong chemical reaction with O, N, H, CO, CO2, water vapor, ammonia gas, etc. in the atmosphere.

l The thermal conductivity is small, the thermal conductivity of titanium is 15.24W / (mK) is about 1/4 of nickel, 1/5 of iron, 1/14 of aluminum, and the thermal conductivity of various titanium alloys is higher than that of titanium About 50%.

2. Application
