26100 mmCLOSEUPDeveloping innovative materials for national projectsIn addition to its own R&D, UACJ participates in national projects in Japan. For example, in a project led by the New Energy and Industrial Technology Development Organization intended to make airplanes lighter and more fuel-efficient, UACJ is developing the world’s strongest aluminum alloy and Heat exchangers are assembled of many precisely formed parts, including aluminum parts that are brazed together by using filler metal. While this is the Helping reduce vehicle weight with lightweight aluminum bumper assemblies UACJ has developed lightweight bumper assemblies in collaboration with major automakers. It helped optimize the materials and construction of each component of the assemblies while aiming for the highest level of strength, superior design, and light weight. As a result, the assemblies are about 30% lighter than conventional products. High-strength aluminum alloy for increasingly large smartphonesManufacturers have been concerned about insufficient strength of smartphone bodies as screens have become increasingly larger. In response, UACJ developed ZK75, a high-strength 7000-series extruded aluminum alloy specifically for smartphones and similar devices. Featuring twice the strength of widely used 6000-series alloys and offering outstanding alumite properties, ZK75 is highly suited for products that require a stylish design and beautiful color finish. Aluminum brazing technology enables higher quality and productivityconventional method, UACJ has developed a technology by which sections of the aluminum parts themselves are melted and then joined together using the molten aluminum instead of the filler metal. This new technology, named Monobraze, has been attracting attention for its ability to maintain quality, such as through excellent corrosion resistance, and enable more efficient manufacturing.enabling it to be produced domestically. UACJ expects that the technologies developed through this project will also be useful in other areas, including product development in the auto industry. Examples of recently developed products and technologiesDeveloping value-added materials that contribute to customers’ productsUACJ carries out product development in close cooperation with its group companies and customers in order to tailor products to their respective needs. Through various means, such as recreating and assessing its customers’ production environments, UACJ develops products that help its customers solve problems in their manufacturing operations.
