UACJ Corporation

UACJ Corporation is a Japanese rolled aluminum manufacturer that promotes the development of aluminum materials, looking five, ten and twenty years ahead.
尽管UACJ公司仍是一个陌生的company in the auto parts field in Europe and the United States, it is a high-quality rolled aluminum manufacturer with the third largest production capacity in the world and reliable technological development capabilities based on a long history of research and development.
We consider social responsibility and sustainability as the most important aspects and strive to reduce the environmental impact of aluminum in all manufacturing steps.
We are committed to working with our customers to develop optimal aluminum automobile parts.


We manufacture the Mazda MX5's body and chassis components. A typical example of the MX-5's lightweight design is the front bumper, which is made from 7000-Series aluminum alloy. The bumper is an important strength element for crushable zone shock absorption. It is also the element furthest from the vehicle's center of gravity, so weight reduction is important to reduce the yaw moment of inertia. Based on these required performances, we have developed materials and extrusion processes and realized the production of thin-walled hollow bodies for bumpers using a high-strength 7000-Series aluminum alloy. This newly developed aluminum alloy has excellent weldability.
Major advantages of using aluminum are its low weight and high recyclability. Compared to the recycling of aluminum from ore (bauxite) to produce aluminum ingots, the energy required to recycle it into aluminum ingots is only 3%. In Japan, the public and private sectors are jointly developing more advanced recycling technology. The recycling technology is "upgrade recycling" that removes impurities and produces high-purity recycled aluminum ingots. Through the widespread use and recycling of rolled aluminum products, we can reduce environmental impact and contribute to the realization of a sustainable mobility society.
