Titanium has a specific gravity of only 1/2 that of iron, yet it stands up to hammering and stretching like copper.

In the ultra-low temperature world, titanium will become harder and have the performance of superconductors, steel becomes fragile and incompetent.

Titanium has a strong resistance to acid and alkali corrosion, immersed in seawater for 5 years without rusting, steel in seawater will corrode and deteriorate. Use titanium alloy to make shells for ships, seawater can not corrode it. Made of titanium alloy “titanium submarine”, can be submerged to a depth of 4500 meters, the general steel submarine in more than 300 meters is easy to be water pressure pressure bad.

In the space industry, titanium can be made into a spaceship “coat”, anti-high-temperature attack.

Titanium and nickel alloy, was made into a “memory alloy”. This alloy is made into a pre-determined shape, and then after stereotypical treatment, if deformed by external forces, as long as a little heat can be restored to its original appearance. This kind of alloy has been applied in many fields. Such as the U.S. Apollo spacecraft antenna, is this memory alloy; Shanghai First Medical College Affiliated Ninth People's Hospital has been used in this memory alloy for women's sterilization surgery; in addition can also be used in the field of instrumentation, electronic devices and so on.

Titanium carbide (TiC) is quite like iron carbide, with a metallic luster. It has a higher melting point and higher hardness than iron carbide. Therefore, it has practical application value.

With titanium utensils to save food, utensils will not be corroded to produce ions, food can maintain the original flavor; titanium cookware is lightweight and high strength, but also will not rust, the most scientific and hygienic.

Titanium in the application of surgical medical procedures, but also very fascinating. Stainless steel, the use of stainless steel has a disadvantage, that is, after the healing of the bone, the stainless steel piece to be taken out again, which is a very painful thing. Otherwise, stainless steel will be rusted and harmful to the human body. If the titanium “artificial bone” will make orthopedic technology completely changed. In the head of the damaged place, with titanium and titanium screws, after a few months, the bone will grow again in the titanium piece of small holes and screws, the new muscle fibers are wrapped in titanium sheet, titanium bones like real bones and flesh and blood connection, play a supportive and reinforcing role, so titanium has been praised as a “pro-biotic metal”. It has begun to be used in knee joints, shoulder joints, rib joints, skull, active heart valve, bone fixed clamps and so on.

In the steel industry, small amounts of titanium are good deoxidizers, nitrogen removers and sulfur removers.

Barium titanate crystals are widely used in ultrasonic instruments and underwater detectors. This is because has a pressure chopping change shape when the current will be generated; once energized will change shape again. Putting barium titanate in ultrasonic wave, it will produce electric current when it is pressurized, and the strength of ultrasonic wave can be measured by the size of the electric current it produces; on the contrary, it can produce ultrasonic wave when it is passed through by high-frequency electric current.

In decorating crafts and daily necessities with gold, they are not durable due to their low hardness, easy to puncture and wear. When a layer of titanium nitride is plated on the surface of these substances, the appearance is almost identical to that of gold plating, but is more wear-resistant than gold and cemented carbide, and the plating is said to be “never-wearable”.

Organic titanium polymers can be used as surfactants, dispersants, water-resistant agents or rust inhibitors.

Titanium is one of the four series of hydrogen storage metals used by mankind, and it is also one of the cheaper ones, but mankind has not yet found a more ideal “hydrogen storage metal”, and once this problem is solved, people will be able to use hydrogen as a fuel.
