Titanium was discovered by British scientists from ore in 1791, but it was not until 1936 that magnesium sponge was used to produce titanium sponge. Industrial production began in 1948, and it has been widely used in various fields of the national economy and plays a huge role.

The development of traditional metal building materials, especially roofing materials, has evolved in the order of copper, surface treated steel sheets, aluminum, stainless steel and titanium. With the advancement of the times, people's requirements for urban buildings, especially for the aesthetics of buildings, are becoming more and more demanding. With the development of the construction industry, architects in recent years have pursued the use of more advanced building materials than traditional materials. The excellent properties of titanium make it fully meet the many performance requirements of building materials and are therefore highly appreciated by architects and the construction industry.

First, the performance of building titanium

Architects chose titanium as a building material. Although many factors were considered, it was mainly based on a series of properties that can be used as building materials.

1. Can meet the requirements of lightweight building materials

The density of titanium is small, about 60% of steel, 50% of copper, and 1.7 times of aluminum, but it has almost the same strength as ordinary steel. As a building, it can reduce weight by 70%~75%, easy to hoist, and can make buildings. The center of gravity of the object moves down to improve the overall seismic capacity of the building.

2. Good corrosion resistance

Titanium has good corrosion resistance: it can withstand urban pollution, industrial radiation and extreme erosion. Therefore, it is suitable for use in marine climates.

3 low coefficient of thermal expansion

Compared with other metal building materials, titanium has a small coefficient of thermal expansion, which is about 50% of stainless steel and 30% of aluminum. It is close to glass, brick, cement and stone, suitable for its sharing, and can be titanium in design. Features with glass. The thermal stress of titanium is very low, 1/2 of stainless steel and 1/3 of aluminum. Titanium can be used as a monolithic material and does not require seams to compensate for thermal expansion and contraction.

4. No environmental pollution

With the development of society, people's requirements for environmental protection are getting higher and higher, and the desire to return to nature is getting stronger and stronger. Because titanium has good corrosion resistance, it can be 100% recycled, does not pollute the environment, and meets environmental protection requirements. On green materials.

5 long service life

Titanium is used as a building material and decorative material to resist centennial corrosion without maintenance and repair. From this perspective, it is clearly superior to other metals. This advantage is particularly acute in highly corrosive environments such as coastal cities and industrial areas. Considering the long life cycle of titanium, its long-term cost performance exceeds that of all stainless steels. Titanium building materials do not require maintenance materials, and titanium buildings do not require maintenance measures.

6. Processability and welding performance are good

Titanium is easy to process into a thin plate and has good welding performance. Titanium itself has a shiny silver-white luster that can be treated to give a brighter surface. In order to achieve a more beautiful decorative effect, different patterns and colors can be obtained by etching and anodizing, and the roof can be made into various shapes as needed, and colored colors can make the whole building a The perfect piece of art.

Second, the application of titanium in the field of construction

Japan is in a leading position in titanium for construction. Titanium for construction has been in Japan for 28 years and has hundreds of buildings. In all kinds of titanium buildings, in addition to housing items, there are also outer walls, curtain walls, sealing slabs, ceilings, harbor facilities, bridges, undersea tunnels, decorations, monuments, railings, pipes, and anti-corrosion coatings. Wait. Titanium has opened up new development space in the construction field.

Timet, the world's largest titanium company, has promoted the application of titanium in the construction sector, offering not only a wide range of products, but also a 100-year warranty.

Currently, buildings in the United States, Spain, the Netherlands, Canada, the United Kingdom, Belgium, Switzerland, and France use titanium as the roof and curtain wall. Some new titanium buildings in countries such as Sweden, Singapore and Egypt are also under construction. Abu Dhabi Airport also used titanium first, and the amount was nearly 100 tons. The airport is the world's first application example of using titanium as a building structural material.
