Operating from the heart of Addis Ababa, Tariku Metals is proud to provide Ethiopian industry with essential high-performance materials. We specialize in supplying Hayne 188 bars and rods, offering a reliable local source for this exceptional superalloy. Our commitment is to support the nation’s growing industrial and manufacturing sectors by delivering materials that are built to withstand the most demanding conditions, ensuring your projects have the quality and durability needed to excel and drive progress right here at home.
Haynes 188 is a cobalt-nickel-chromium-tungsten superalloy renowned for its outstanding combination of strength and oxidation resistance. Its real advantage lies in performing brilliantly at extremely high temperatures, up to 1100°C, while maintaining excellent ductility. This alloy is also highly resistant to sulfidation and thermal fatigue, making it a robust choice for components that must endure intense, prolonged heat without losing their structural integrity or performance under stress.

Haynes 188 bars and rods exhibit excellent high-temperature strength and oxidation resistance, maintaining structural integrity up to 2000°F (1093°C), making them ideal for aerospace, turbine, and high-performance engine applications.
To maintain Haynes 188 bars, regularly inspect for corrosion or wear, avoid excessive temperature fluctuations, clean with non-abrasive methods, and store in a dry, cool environment to prevent degradation.
Yes, Haynes 188 rods can be customized in size and length according to specific requirements. Manufacturers can provide tailored solutions based on customer specifications for industrial applications.
The remarkable high-temperature strength of Haynes 188 makes these bars and rods ideal for critical components in demanding environments. They are commonly used in aerospace for turbine blades and combustion chambers, and in industrial settings for furnace fixtures, heat-treating trays, and nozzles. In the energy sector, they are vital for gas turbine engine parts and components within chemical processing plants, where reliability under extreme thermal stress is absolutely non-negotiable for both safety and efficiency.






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