Introduction

■Characteristics of Titanium

 Titanium, which was found in the 1790s, is the 4th most abundant practical metal existing in the upper crust of the earth. It has taken a long time before an industrial refining process for titanium was reached to completion, and not until 1946 did industrial production of this new metal, titanium begin. The metal was adopted for aerospace applications for the beginning, owing to its specific strength. And then, the demand for titanium, which also has outstanding corrosion resistance, began to increase markedly for such applications as Chemical industries and Electric power generation. Today, titanium is a well-known material for its character from aesthetic and for environmental and biological conformity. Titanium, which has excellent physical properties and is friendly to the environment, meets contemporary needs from the world and has a great potential for an expected growth in the future.  Nippon Steel & Sumitomo Metal Corporation, which was founded in 2012, as a world top-class comprehensive producer of titanium mill products, supplies its high-function, high-quality products and services to the customers by utilizing the best effectiveness of the consolidated management resources of the new corporation and the specialized expertise of the companies.  Based on the results of basic studies of titanium which has been obtained for many decades, with its more strengthened organization and staffs of research and development, we continue R&D for various fields of titanium application, such as Chemical industries, Electric power generation, Seawater desalination, Civil engineering, Architecture, Automotive, Consumer appliances, and Aerospace industries, etc. We are also developing new applications of titanium actively aiming to customers needs.  Nippon Steel & Sumitomo Metal Corporation is to pursue the infinite potential of the contemporary metal, Titanium .

Titanium has superb seawater corrosion resistance and hence is ideal for parts used in seawater.

Titanium has a specific weight of 4.51, about 60% that of steel.

CONTENTS Characteristics of Titanium

Outstanding corrosion resistance

Small thermal expansion Titanium is comparable in thermal expansion to glass or concrete.

Nonmagnetism Titanium is not magnetized.

Aesthetics Unique texture of metal surface and various menu of surface finish.

Physical Properties

Comparison of corrosion resistance between titanium and other metallic materials

The advantageous physical properties of pure titanium are as follows.

①Light weight 【Specific gravity】 (60% of specific gravity of steel and about 1.7 times that of aluminum) ②Low thermal expansion 【Hermal expansion coefficient]】 (ne-half that of 18-8 stainless steel and one-third that of aluminum) ③Low hear conductivity 【Heat conductivity】 (nearly the same as 18-8 stainless steel) ④Low electric conductivity【Electric conductivity】 (about 3% of copper) ⑤High flexibility 【Longitudinal elastic modulus】 (one-half of iron or stainless steel and the same as copper) ⑥6 Non-magnetism 【Magnetic permeability】 (non-magnetic material; magnetic permeability = 1.0001)
