Titanium powder will burn when cutting titanium, which is very dangerous. A large amount of tiny titanium dust can catch fire and explode, so the production, casting, and processing of titanium should have good ventilation and dust-proof facilities, as well as fire-proof and explosion-proof equipment. This property of titanium powder is also used to make fireworks.

Titanium has high strength, and the tensile strength of pure titanium can reach up to 180kc)/mm2. Some steels are stronger than titanium alloys, but the specific strength (the ratio of tensile strength to density) of titanium alloys exceeds that of high-quality steel. In the live ammunition shooting test, it was found that a single shot of titanium alloy plate is difficult to penetrate, which is better than aluminum plate and steel plate.

Titanium is “biophilic”. In the human body, it can resist the corrosion of secretions and is non-toxic, and is suitable for any sterilization method. Therefore, it is widely used in the manufacture of medical equipment, artificial hip joints, knee joints, shoulder joints, rib joints, skulls, active heart valves, and bone fixation clips. When new muscle fiber rings are wrapped around these “titanium bones”, these titanium bones begin to maintain the normal activities of the human body.
It has been confirmed that titanium can stimulate phagocytes and enhance immunity. Titanium metal is non-toxic, so we also use titanium alloy for dental implants. Of course, foodies, don’t eat titanium just because of this. After all, metal is indigestible, and even a little bit can kill you.

In the earth’s crust, the reserves of titanium are second only to iron, aluminum, and magnesium, ranking fourth. Titanium metal is increasingly valued by people, known as “modern metal” and “strategic golden class”, and is an indispensable and important strategic material for improving the level of national defense equipment.

For rockets, missiles and spacecraft in the sky, the selection of materials requires careful calculation and selection. Not only do materials need to be light and strong, and they have good performance under high and low temperature conditions, but they also need to be light in weight. After using titanium alloy processing materials instead of steel on rockets, missiles, and spacecraft, the weight can be reduced by nearly 1/3, which can greatly improve their flight performance. Due to the reduced weight, a large amount of expensive advanced fuel can be saved, and the cost of construction and launch can be reduced.

In recent years, many new titanium alloys have been researched and trial-produced, and their tensile strength is above 100 kilograms per square millimeter. These titanium and titanium alloys are mainly used to manufacture fuel and oxidant storage tanks for rockets and missiles, and other high-pressure containers, as well as rockets, missile shells, and spacecraft cabins.
