Copper and Brass are the cornerstones of modern electrical, plumbing, and mechanical engineering. While Copper provides unmatched thermal and electrical conductivity, Brass alloys offer superior machinability, spark resistance, and durability in marine and industrial environments.
Our Copper range features high-purity ETP and Oxygen-Free grades for critical electronics. Our Brass portfolio includes Free-Cutting and Naval grades, providing the perfect balance of strength and corrosion resistance for marine hardware and precision-turned components.

High Thermal Conductivity
Precision-drawn tubes for heat exchangers, plumbing, and electrical busbars. Copper tubes offer peak thermal transfer, while Brass tubes provide the structural rigidity and corrosion resistance needed for condenser systems.
Solder & Threaded Connectors
Comprehensive range of elbows, tees, and couplings. Brass fittings are favored for their excellent threadability and spark-resistant nature, making them safe for volatile fuel and gas lines.
Electrical & Decorative Grade
Highly ductile flat products. Pure copper sheets are essential for electrical grounding and architectural roofing, while brass plates are used for heavy machinery wear strips and decorative inlays.
Marine Sealing Solutions
Forged brass and copper-alloy flanges designed for low-to-medium pressure water systems, marine valve connections, and decorative architectural piping.
Free-Cutting / High Machinability
Industrial-grade bars for electrical terminals and high-speed machining. Free-cutting brass (C360) is the global benchmark for machining speed and tool life.
