Titanium building materials are characterized by being “lightweight,” “strong,” and “durable. Pure titanium is also one of the building materials that can be processed in a variety of ways because it is relatively soft.
Taking advantage of these characteristics, titanium is used for roofing, metal fittings, and interior applications in long-term durable construction.
Currently, the SDGs include the goal of “creating cities where people can continue to live,” and it can be said that titanium, with its long-term durability, is one of the building materials that will play an active role in realizing a sustainable society in the future.
In this article, I will explain the long-term durability functional expression using titanium with these features, based on some examples.

Features of Titanium Building Materials
The following are typical features of titanium building materials.
(1) Outstanding weather resistance (especially in salt-damaged areas near the sea)
(2) Light weight
The specific gravity of titanium is 4.51, which is a little more than half the weight of stainless steel and iron, which have a specific gravity of about 8, making it lightweight.
(3) High specific strength
The specific strength of titanium is twice that of iron and three times that of aluminum.
(4) Less susceptible to expansion
The coefficient of thermal expansion is small, and dimensional changes due to heat are minimal.
1/2 of stainless steel, 1/3 of aluminum.
(5)Gentle on the human body
No elution of metal ions, making it very gentle to the human body.
(6) Hard to feel cold
Volume specific heat is 60% of that of iron and stainless steel.
A small amount of heat warms it up, so it is less likely to feel cold to the touch.
The Guggenheim Museum is a world-famous example of titanium building materials with these characteristics.
Price of Titanium Building Materials
When considering titanium building materials, the most important thing to consider is the price, isn’t it?
A simple comparison of materials shows that the price of titanium is more than ten times higher than that of stainless steel for the same weight.
The price of titanium is ten times higher than that of stainless steel. But
However, the fact is that the aforementioned weight is more than half that of stainless steel, and because of its high specific strength, it is possible to make the material thinner.
By making the material thinner, it is possible to create a more realistic construction.
Applications of Titanium Building Materials
Titanium roofs that transcend the ages
Titanium is light, strong, and corrosion resistant, making it ideal for long-term durable construction.
In particular, the roofs of temples and shrines are much lighter than conventional tile roofs.
In addition, it maintains its appearance and performance without corrosion for a long time. For this reason, the most common application of titanium is currently in materials related to temples and shrines.
Shrines and temples are rooted in the community and pass on the culture, climate, and history of the land to the next generation.
They are buildings that need to exist in the flow of eternal time.
Therefore, titanium, which can overcome the flow of time, is chosen.
Ryuoh Shrine, with its golden pure titanium roof, is located in Kumamoto Prefecture.
With its majestic appearance and long-term durability, you can feel the blessings that have been passed down from generation to generation.
Titanium fittings that transcend time
However, recently, titanium fittings with high long-term durability have been developed and adopted mainly for decorative fittings.
Like roofing, titanium metal fittings are durable, light, and strong, but they are not only that. Their low specific heat of volume makes them very gentle to the wood frame.
These titanium fittings can coexist gently with buildings while maintaining long-term durability.
We installed titanium decorative metal fittings “”Rokuba”” at shrines and temples in Hiroshima Prefecture.
Many people have an image of titanium as a “brownish-silver” metal, but one of the characteristics of titanium building materials is that they can express a variety of colors.
However, titanium building materials can be used to create a wide variety of colors, not by painting or plating, but by altering the surface of titanium itself. Therefore, titanium building materials are free from weather deterioration and cracking.

Titanium building materials that can be processed in various ways
There are a lot of rumors out there about titanium being hard and difficult to work with, difficult to weld, and impossible to cut. These rumors refer to titanium alloys used in aircraft and medical equipment.
Titanium alloy is literally titanium fused with various metals to enhance its performance.
In concept, it is like stainless steel, which is made by mixing iron with chromium and nickel.
In other words, iron is soft, while stainless steel is hard.
The same thing can happen with titanium.
Titanium is originally pure titanium. Titanium is originally pure titanium, and titanium alloys are made by dissolving metals into the pure titanium.
Therefore, pure titanium is relatively soft and easy to process.
This is a temple in Koyasan.
The roof is made of black titanium.
And shining in gold is the golden titanium jewel.
This golden titanium jewel is made by an all-welded process.
Since the technique of spatula drawing was not available, the craftsman made a development drawing and welded it together like the skin of an apple.
The weld marks are cleaned up by design polishing and then IP Golden processing is performed.
As you can see, titanium building materials can be processed into a variety of shapes and have both a beautiful appearance and long-term durability.
Titanium building materials used in interior design
Many people think that titanium building materials are appropriate for exterior applications because of their lightness, strength, and long-term durability, but they are actually also used for interior applications.
The outside of a building must last for decades, but the inside will last for decades as well.
While Japan has four distinct seasons, it also has high humidity and cold differences.
Therefore, by installing titanium building materials on the interior walls, it is possible to form strong interior walls.
Titanium building materials have excellent abrasion resistance and high corrosion resistance, which makes it possible to use alcohol and solvents, and to regenerate the beautiful surface many times.
In this way, titanium building materials are also used in interior decoration to maintain a sustainable environment.
A temple used for interior decoration.
It will not only last for a long time, but also contribute to the daily care of the temple.
Expanding Applications of Titanium Building Materials
Titanium building materials, a sustainable metal with long-term durability, originated in traditional architecture.
Recently, it has been accelerating its development in a variety of applications.
It is beginning to be used in a variety of applications, from outdoor use to art.
Fields that require long-term durability such as monuments and signs
Works by calligraphers and artists passed down from generation to generation
Titanium products that combine function and durability
And nice titanium.
However, another feature of titanium building materials is that they are “nice”.
It is light, strong, and corrosion-resistant. 。。。。 Nice titanium
Titanium is a metal that has only just been born.
The practical use of titanium is finally underway.
The expression of “nice titanium” is evolving one after another.
A New Look for Designing Titanium
The texture variation of golden titanium is a design titanium that can be fully customized to meet the needs of customers.
Finally
In this article, I introduced titanium building materials, a metal with long-term durability, in response to the SDGs goal of “building communities where people can continue to live” to see what we can do for the earth in the future.
Of course, like any other metal, titanium is melted down again and regenerated when it has finished its role.
A large amount of carbon is now needed to create the metal.
But once it is extracted, it can be regenerated repeatedly by the power of electricity.
In the future, when the supply of electric energy becomes greener, metals will be a very earth-friendly material.
Among them, titanium building materials, which are highly durable and take a long time to regenerate, will play an increasingly important role in the future.
