Daechang’s R&D Center is a specialized research organization that has accumulated more than 30 years of expertise in non-ferrous metals and special copper alloys since the company was founded.
It develops core technologies in-house to meet industrial demand across corrosion-resistant copper alloys, eco-friendly lead-free brass, precision-processing alloys, and nano materials, and currently holds 30 domestic registered patents.
In response to global environmental regulations, the center continues to develop lead-free brass alloy technology that eliminates lead content. It has commercialized application-specific eco-friendly alloys such as bismuth-inclusion spheroidized lead-free brass, high-strength lead-free brass, and low-silicon lead-free brass, helping supply safer materials for drinking-water valves and plumbing systems.
The center develops special alloys that meet demanding industrial requirements, including high-strength wear-resistant copper alloys for synchronizer rings, brass electrode wire for wire EDM, and filler materials for dissimilar metal joining. It continues to secure precision material technology applicable to automotive, electrical and electronics, and semiconductor equipment industries.
Research is expanding into next-generation functional materials including flame-synthesis copper oxide nanopowder, copper oxide production technology for printed circuit boards, and porous copper-based antimicrobial filter technology.
