- PT Tembaga Mulia Semanan Tbk is an Indonesia-based company primarily engaged in the manufacturing of copper rods, copper wires, aluminum rods, and aluminum wires. The company operates through two main segments: Copper Rod and Wire, which produces copper rods and various sizes of copper wire, and Aluminum Rod, which manufactures electrical conductor (EC) grade rods, alloy rods, and target analyte list (TAL) rods. Besides manufacturing, PT Tembaga Mulia Semanan is involved in metal recycling activities for copper and aluminum, trading of metals and metal ores domestically and internationally, as well as non-ferrous metal foundry and mill industries. The company has an annual production capacity of approximately 155,000 tons, including about 100,000 tons of copper rods and 55,000 tons of aluminum rods. It serves both domestic and export markets, with significant sales in Indonesia and growing international exports. Founded in 1977 and headquartered in Jakarta Barat, Indonesia, PT Tembaga Mulia Semanan was the first copper rod supplier in Indonesia using the Southwire Continuous Rod system, expanding later to include aluminum rod production through acquisition in 2001.
Recent major company developments include steady financial growth highlighted by a net profit increase to Rp 144.8 billion in 2024 from Rp 95.3 billion in 2023, reflecting improved operational performance. The company has also continued to expand its production capacity and export market share, supporting its strategic focus on quality and customer satisfaction with certifications like ISO 9001:2015 and ISO 14001:2015. PT Tembaga Mulia Semanan has announced plans for a stock split with a ratio of 1:2 in early 2024 to increase market liquidity. In the latest financial year, the company undertook technological collaborations aiming at developing new fine wire products, enhancing its product offerings to meet evolving market demands. Its financial reports and annual general meetings in 2024 and 2025 reflect a stable corporate governance structure supporting ongoing business expansions and operational improvements.
The company primarily targets the metals and mining industry segment, specializing in nonferrous metal processing, with clients in the electrical, construction, and manufacturing sectors across Indonesia and other countries. The combination of manufacturing, metal recycling, and trading alongside progressive product development positions PT Tembaga Mulia Semanan as a significant player in the Indonesian and regional copper and aluminum industries.
