Welcome to Tariku Metals, your trusted partner in the heart of Addis Ababa for high-performance metal solutions. We take pride in manufacturing and supplying premium Nilo Alloys in bar and rod forms, engineered to meet the rigorous demands of modern industry. Our commitment lies in delivering materials that combine exceptional quality with reliable performance, supporting Ethiopia’s growing infrastructure and technological advancements with products you can depend on for critical applications.
Nilo Alloys are a specialized family of nickel-iron alloys, renowned for their unique and predictable thermal expansion characteristics. Certain grades feature a very low expansion rate, while others are designed to maintain a constant rate across a wide temperature range. This, combined with their excellent strength and durability, makes them remarkably reliable in environments subject to significant heat fluctuations, ensuring consistent performance where other materials might fail.

Nilo alloy bars and rods excel in high-temperature environments due to their excellent thermal stability, low thermal expansion, and resistance to thermal shock, making them ideal for high-precision applications.
Yes, Nilo Alloy rods can be customized in size and length to meet specific requirements. Manufacturers typically offer tailored solutions based on customer needs for various applications.
To maintain Nilo Alloy bars, clean regularly with a mild detergent, avoid harsh chemicals, store in a dry environment, and inspect for wear or corrosion. Lubricate if necessary.
The unique properties of Nilo Alloys make them indispensable in precision engineering. They are primarily used in components where dimensional stability is critical, such as in glass-to-metal seals for electronics and lighting, precision measuring instruments, and thermostat rods. These bars and rods are also essential in applications like laser cavities and aerospace components, where even the slightest expansion or contraction could compromise the entire system’s accuracy and functionality.






We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
