The difference between titanium anode and titanium alloy

Titanium is an important structural metal developed in the 1950s, and titanium alloy is widely used in various fields because of its high strength, good corrosion resistance and high heat resistance. Many countries in the world have realized the importance of titanium alloy materials, have carried out research and development on it, and have been practical applications.

The first practical titanium alloy is the Ti-6Al-4V alloy successfully developed in 1954 in the United States, because of its heat resistance, strength, plasticity, toughness, formability, weldability, corrosion resistance and biocompatibility are good, and become the ace alloy in the titanium alloy industry, the alloy has accounted for 75% to 85% of all titanium alloys. Many other titanium alloys can be considered as variants of Ti-6Al-4V alloys.

In the 1950s to 1960s, mainly the development of high-temperature titanium alloys for aeroengines and structural titanium alloys for the body, a number of corrosion-resistant titanium alloys were developed in the 1970s, and since the 1980s, corrosion-resistant titanium alloys and high-strength titanium alloys have been further developed. The use temperature of heat-resistant titanium alloy has been increased from 400℃ in the 1950s to 600 ~ 650℃ in the 1990s. With the advent of A2(Ti3Al) and r (TiAl) base alloys, titanium is being pushed in the direction of the hot end of the engine (turbine) from the cold end of the engine (fan and compressor) in the use of the engine. Structural titanium alloys develop in the direction of high strength, high plasticity, high strength, high toughness, high modulus and high damage tolerance. In addition, since the 1970s, shape memory alloys such as Ti-Ni, Ti-Ni-Fe, Ti-Ni-Nb have also appeared, and have been increasingly widely used in engineering.

At present, the world has developed hundreds of titanium alloys, the most famous alloy there are 20 to 30 kinds, Such as Ti-6Al-4V, Ti-5Al-2.5Sn, Ti-2Al-2.5Zr, Ti-32Mo, Ti-Mo-Ni, Ti-Pd, SP-700, Ti-6242, Ti-10-5-3, Ti-1023, BT9, BT20, IMI829, IMI834, etc.
