In addition to our extensive procurement capabilities from both domestic and international sources, we meet our customers' diverse needs through various inventory, logistics, and processing functions.

Aluminum and its alloys are representative lightweight metals that are close to our daily lives. They form a stable oxide film on the surface known as anodizing, which gives them excellent corrosion resistance and beauty. Additionally, they have excellent workability and sufficient strength, and generally do not have issues with low-temperature brittleness like steel materials. Furthermore, due to their high electrical conductivity and non-magnetic properties, as well as good thermal conductivity, they can also be used in precision machinery and electrical components. They possess characteristics such as good surface treatment properties, non-toxicity, and ease of processing for joining, making them materials that can be utilized in various situations.
