Welcome to Tariku Metals, your trusted partner in Addis Ababa for premium specialty alloys. We take pride in supplying industry with high-performance materials like Grade Mar-M 247, available in both bar and rod forms. Sourced for reliability and engineered for the most demanding conditions, this superalloy is a cornerstone for projects where failure is not an option. We are committed to delivering not just a product, but a solution that empowers Ethiopian innovation and industrial growth, supporting local engineers and manufacturers with materials that meet a global standard of excellence.
Grade Mar-M 247 is a nickel-based superalloy known for its exceptional strength and resilience. Its sophisticated composition includes significant amounts of cobalt, chromium, and tantalum, which grant it outstanding creep resistance and the ability to retain its mechanical properties at extreme temperatures, often exceeding 870°C. This combination makes it incredibly resistant to deformation under heavy loads and high heat, offering a unique blend of durability and long-term performance that is essential for critical applications where ordinary metals would quickly falter.

Yes, Grade Mar M247 bar can be welded using appropriate welding techniques like gas tungsten arc welding (GTAW) or laser welding, but preheating and post-weld heat treatment are often recommended.
Yes, for welding Gr Mar M247 Bar, typically used consumables include Inconel 625, Inconel 718, or similar high-nickel alloys to ensure compatibility with its high-temperature and corrosion-resistant properties.
Grade Mar M247, primarily used for turbine blades, is generally resistant to galvanic corrosion due to its high alloy content. However, galvanic corrosion risk can arise when coupled with dissimilar metals.
The remarkable properties of Mar-M 247 bar and rod make it the material of choice for the most challenging environments. You will find it at the heart of gas turbine engines, forming essential components like turbine blades and vanes that must withstand intense heat and rotational forces. Beyond aerospace, it is critical in high-performance power generation equipment and is increasingly valued for specialized tooling and dies, especially in processes involving high temperatures where its strength and thermal stability prevent premature wear and failure.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
