Based in the vibrant heart of Addis Ababa, Tariku Metals stands as a leading supplier and manufacturer dedicated to quality and resilience. We specialize in providing robust materials engineered for demanding environments, with a particular focus on our superior Copper Nickel 9010 forgings. Our commitment is to deliver components that offer unmatched durability and long-term performance, supporting the ambitious growth of industries across Ethiopia and beyond with reliable, high-integrity solutions built to last.
The specific composition of Copper Nickel 9010, with its 90% copper and 10% nickel blend, is what gives these forgings their exceptional character. This alloy is renowned for its outstanding resistance to corrosion, especially in challenging seawater and marine atmospheres. Furthermore, it possesses impressive mechanical strength and toughness, maintaining its integrity under high stress. It is also highly ductile, allowing for complex fabrication, and retains these superior properties across a wide range of temperatures, making it incredibly versatile.

Copper Nickel 90/10 forgings may face challenges like higher cost, susceptibility to galvanic corrosion in specific environments, and limited availability in some sizes, requiring precise processing and material sourcing.
Common welding processes compatible with Copper Nickel 90/10 forgings include TIG (GTAW), MIG (GMAW), and SMAW. Proper filler materials, such as CuNi rods, ensure strong, corrosion-resistant welds for optimal performance.
Durability of Copper Nickel 90/10 forgings is ensured by factors like corrosion resistance, proper heat treatment, precise manufacturing, adequate welding techniques, and protection against galvanic corrosion in marine and industrial environments.
The unique properties of Copper Nickel 9010 forgings make them indispensable in critical applications, particularly within the marine sector where they are used for essential components like propeller shafts, pump bodies, and underwater fittings. Their reliability also extends to the oil and gas industry for valves and pipe fittings, and to power generation plants for condenser tubes and heat exchangers. Essentially, wherever equipment faces constant exposure to corrosive elements while requiring structural strength, this alloy provides a trusted, long-lasting solution.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
