Titanium is a new metal material that has become a shining "rising star" among many other metals. High purity gr1 titanium is one of the light metals, and pure titanium has many delicate functions. The specific gravity of titanium is of course only 50% of that of steel, but its strength is more than 18% of that of steel, and its ductility is better than that of steel, so it can withstand hammering and stretching like copper. Titanium melting point of 1600 ℃, night and day higher than steel, such as titanium and steel at the same time in the steelmaking furnace, steel melted, and titanium is still simulation is still. In the ultra-low temperature situation steel will become brittle, missing on the ground will be broken, and titanium in -100 ℃ will not become brittle, still has exquisite mechanical function. Titanium also has exquisite acid and alkali resistance and erosion resistance. In strong acid and alkali solutions, steel will be corroded into holes, while titanium is safe; steel will rust and deteriorate quickly in seawater, while titanium will not rust for at least 5 years. Stir-frying with titanium woks will not happen to stick to the pan. Non-stick pans made of titanium have entered the home. Titanium and aluminum have many advantages, titanium hardness is higher than aluminum, more stable than aluminum, not easy to deform; titanium melting point is much higher than aluminum (600 ℃).
Titanium tube by adding aluminum, vanadium, molybdenum, zirconium and other metals, can be obtained containing 90% titanium titanium alloy. Titanium alloy has many exquisite functions such as light weight, strike resistance, tensile pressure resistance, etc. It is a high-level material in machinery, aviation, astronautics and other properties. Titanium alloys as the main system example of the aircraft, high strength, low weight, can advance the speed of about 1 / 3, can night and day to increase the number of passengers (night airliners can add more than 100 people), but also to save fuel. Titanium alloy made of deep-sea probes can dive to a depth of 6500 meters without being crushed, while steel submarines can only dive to 300 meters. In the aerospace and astronautics property, titanium alloy with its exquisite function is generally accepted, launch vehicles, artificial satellites, space shuttles, space stations, planetary probes, etc., year after year, all accept titanium alloy manufacturing shell. This metal shell in the universe under the premise can be strong, in high-speed flight can be strong friction caused by high temperature.
Set in the chemical properties, corrosion-resistant pumps, valves, reflectors and other equipment, these devices set on the titanium alloy more. Titanium is united with nickel, and it is also possible to make "memory alloy" with memory effect. I use this material to make automobile shells, and when it is deformed by a collision, it can be restored to its shape by blowing it with hot air at a temperature of 80c or more.
