Nippon Steel Corporation's newly developed Titanium Alloy Super-TIXTM 20AFG
by TranTixxii" will be adopted in the new G-SHOCK watch to be sold by Casio Computer Co., Ltd.
("Casio” hereafter) in April 2021.
G-SHOCK is a leading Casio watch brand, characterized by shock-resistance capabilities. Numerous G-SHOCK
models are released every year. Nippon Steel's newly-developed titanium alloy has been decided to be used
for the new model GMW-B5000TR bezels and bands.
Titanium is about 60% lighter than stainless steel, has a high-quality feel, is corrosion resistant to
sweat and seawater, and is biocompatible to the human body enabling it to be used for artificial joints
and pacemakers. Although the use of titanium has been adopted to watches and other precision equipment,
there has been a limitation in that titanium is less reflective and workable than stainless steel. The new
TranTixxii Super-TIX 20AFG alloy, jointly developed by both companies for the new G-SHOCK model, has
achieved the same surface reflectance property as stainless steel, and its excellent workability has
contributed to the realization of elegant watch exteriors. Additionally, for models equipped with GPS
functions, it was also a challenge to ensure radio reception characteristics. While satisfying all
properties of surface reflectance, workability, and radio reception had long been regarded difficult in
case the conventional titanium materials, Nippon Steel developed the Super-TIX 20AFG alloy, which
satisfied all these properties by combining optimum blending of chemical composition with fine metal
structure control in microns.
Casio is expanding sales worldwide by increasing the ratio of G-SHOCK watches made of metal. Nippon
Steel’s TranTixxii provides elegance and robustness as expressed in its brand concept
"Materials transcending ages.” The company will continue to vigorously develop materials that
meets the needs of Casio’ products.
■G-SHOCK GMW-B5000
The G-SHOCK watch, made by Casio since1983, has achieved the unique shock-resistance capabilities. It
redefined what was considered to be durability and vulnerability to impact. To date, more than 100 million
watches have been shipped worldwide. G-SHOCK watches are constantly evolving as the only brand that goes
beyond the genre of watches. The GMW-B5000 has the design of the first G-SHOCK model, with a full-metal
case. The model also has unique designs in a variety of the CMF (color, material, and finishing).
■ TranTixxii Designing Titanium
TranTixxii is the first titanium brand in the world, which can be made with a variety of colors and color
tones, thanks to Nippon Steel’s advanced technologies. The colors and tones can be sustained with
the excellent corrosion and color permanence properties of titanium. Nippon Steel’s Titanium
TranTixxii, owing to its functionality, design-friendliness, and formability of the material, is being
used widely in architectural applications such as roofs and walls that both protect and decorate homes and
buildings, as well as louvers, doorplates, creasing, and other building components.
