Aluminum Sheets & Plates

Aluminum sheets and plates are superior to other metals in lightness, strength, workability, rust resistance, recyclability, environmental friendliness and many other properties. This distinction is the reason for the material's successful role in food (e.g. beverage cans), transport (including automotive and aeronautical), electric and chemical sectors, As market demand for aluminum sheets and plates increase, quality requirements made by users are becoming increasingly diversified and sophisticated. Sumitomo Light Metal Industries is further improving thin sheet manufacturing and surface treatment technologies, in which the company excels, and striving to become a globally competitive high-performance material producer with original know-how and expert quality control.

Aluminum Extrusions (by Sumikei Techno Group)

Aluminum extrusions, with their ability to be molded into elaborate and complicated shapes as well as the material's excellent functionality, have applications in many fields including transportation, IT and machinery. In recent years, increased demand in non-construction materials sectors-automotive materials for instance- has caused higher quality requirements. Sumitomo Light Metal Industries has been refining its technical ability in order that advanced requirements, such as porous tubes for automotive heat exchangers in car air conditioning system, are satisfied by the company's high-precision sizing and unique manufacturing technologies.

Copper Products (by Sumikei Copper Tube)

Due to its excellent heat conduction and microbial resistance, copper has extensive use in room air conditioning system, industrial heat exchangers, cold and hot water supply piping and many other applications. Since 1897 when Sumitomo Copper Rolling Works was founded, Sumitomo Light Metal Industries has been fabricating high quality and high precision copper tubes. Our century-old experiences and proven techniques have won customers' unshakable trust.
