Aluminum alloys are used in all scenes in our daily life for a
variety of applications, such as car bodies, engine components,
optical devices including cameras, home electric appliances, and
housing materials. Needless to say, the chemical ingredients of
aluminum alloys vary with the product applicable.
Daiki has been responding to such diversified needs steadily. After
adding a variety of metals in units of ppm to aluminum scraps while
taking advantage of the characteristics of aluminum, Daiki has been
producing versatile aluminum alloys by melting and refining the
Although aluminum alloys are made from aluminum as a major ingredient,
finished aluminum alloys are very different in metal characteristics.
Some of them may be excellent in castability, corrosion resistance,
and impact resistance. Other ones may be excellent in machinability,
tensile strength, and pressure tightness. Daiki's cultivated technology
is applied to the production sites where aluminum alloys are newly
as a pioneer in the aluminum alloys industry has been achieving
substantial result and developing casting technology since its establishment
in 1922. Daiki products are highly evaluated not only in Japan but
also overseas and ranked as a benchmark(index and standard) in the
You cannot see Daiki's <DIK> trademark on processed Daiki
products used as part of finished consumable products. A large number
of Daiki's aluminum alloys are, however, playing important roles
all over the world.
