Screw manufacturer Titanium alloy screw manufacturer: What is titanium and what are its applications?

Titanium used in chemical industrial plants was the earliest to be developed, and there are currently no new projects, mainly through cost reduction to replace other materials and expand applications. Currently, the price of titanium has been reduced by half compared to 20 years ago, and titanium can be used as a substitute for stainless steel. Sumitomo's SIM-ACE alloy system will demonstrate its expertise in this field. From 1992 to 1993, Japan's chemical industry showed a downward trend, starting to climb in 1994, reaching its peak of 2543 tons in 1997, and then declining again in 1998, By 1999, it was 1368 tons and began to recover in the second half of 2000. It is expected that this recovery situation will continue in 2001, with an estimated loading capacity of up to 1900 tons

Titanium and Construction Industry

1. Introduction

Titanium was discovered by British scientists from ores in 1791, but it was not until 1936 that the magnesium reduction method was used to produce sponge titanium. Industrial production began in 1948 and has been widely used in various fields of the national economy, playing a huge role. The development of traditional metal building materials, especially roof materials, developed in the order of copper, surface treated steel plates, aluminum, stainless steel, and titanium. With the progress of the times, people's requirements for urban buildings have increased, Especially, the requirements for the aesthetics of buildings are becoming increasingly high; With the development of the construction industry, in recent years, architects have pursued the use of building materials that are more advanced than traditional materials. The series of excellent properties of titanium enable it to fully meet many performance requirements of building materials, which has been highly favored by architects and the construction industry

2. The performance of building titanium

Architects choose titanium as a building material, although considering various factors, mainly based on a series of properties of titanium that can be used as a building material

2.1 Can meet the requirements of lightweight building materials

Titanium has a low density, about 60% of steel, 50% of copper, and 1.7 times that of aluminum. However, it has almost the same strength as ordinary steel, and as a building, it can reduce weight by 70% to 75%, making it easy to lift and move the center of gravity down, improving the overall seismic resistance of the building

2.2 Good corrosion resistance

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

2.3 Low coefficient of thermal expansion

Compared with other metal building materials, titanium has a small coefficient of thermal expansion, about 50% of stainless steel and 30% of aluminum. It is close to glass, brick, cement and stone and is suitable for sharing. It can highlight the characteristics of titanium and glass in design. Titanium has a very low thermal stress, which is 1/2 of stainless steel and 1/3 of aluminum. Titanium can be used as a whole material without joints to make up for thermal expansion

2.4 No Environmental Pollution

With the development of society, people's demands for environmental protection are increasing, and their desire to return to nature is becoming stronger. Due to its good corrosion resistance, titanium can be 100% recycled without polluting the environment, meeting environmental requirements, and can be called a green and environmentally friendly material

2.5 Long service life

Titanium is used as a building material and decorative material, which can resist corrosion for hundreds of years without maintenance and repair. From this perspective, it is clearly superior to other metals. This advantage is particularly prominent in highly corrosive environments (such as coastal cities and industrial areas). Considering the long service life of titanium, its long-term cost performance exceeds all stainless steel, and titanium building materials do not require maintenance measures, so titanium buildings do not need maintenance measures

2.6 Good processability and welding performance

Titanium is easy to process into thin plates and has good welding performance. Titanium itself has a shiny silver white luster, and through treatment, a brighter surface can be obtained. In order to achieve a more beautiful decorative effect, different patterns and colors can be obtained through etching and anodizing treatment. According to needs, the roof can be made into various shapes, combined with colorful colors, which will make the entire building a perfect artwork
