From the heart of Addis Ababa, Tariku Metals is proud to be a trusted local source for high-quality industrial components. We specialize in the manufacturing and supply of Copper Nickel 7030 forgings for Ethiopia’s demanding industries. With a deep commitment to precision engineering and reliable service, we deliver forgings that meet the toughest standards. Our focus is on supporting our nation’s growth by providing durable, corrosion-resistant solutions that you can count on for your most critical applications.
The distinctive strength of Copper Nickel 7030 comes from its balanced composition, primarily 70% copper and 30% nickel, with small additions of iron and manganese. This alloy is engineered to offer excellent mechanical properties, including high tensile strength and outstanding ductility. It maintains its integrity under stress and is remarkably resistant to thermal expansion. Most importantly, it possesses a proven toughness that stands up to both impact and fatigue over long periods, making it a reliably robust material.

The durability of Copper Nickel 70/30 forgings is ensured by excellent corrosion resistance, high tensile strength, superior weldability, resistance to seawater, anti-biofouling properties, and consistent alloy composition for enhanced performance.
Copper Nickel 70/30 forgings offer superior strength, enhanced corrosion resistance, improved material utilization, reduced waste, better grain structure, and higher durability compared to machining, making them ideal for demanding applications.
Compatible welding processes for Copper Nickel 70/30 forgings include TIG (GTAW), MIG (GMAW), and shielded metal arc welding (SMAW), ensuring strong joints, excellent corrosion resistance, and minimal thermal distortion.
These forgings are indispensable in environments where failure is not an option. You will find them hard at work in critical marine systems, such as seawater piping, pumps, and valves, where their superb corrosion resistance is vital. They are also essential in the oil and gas sector for fittings and manifolds, and in power generation plants for condenser tubes. Essentially, wherever components face constant exposure to aggressive saltwater or high-pressure steam, Copper Nickel 7030 forgings provide the long-lasting, dependable performance that keeps operations running smoothly.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
