Mourad Metals, based in Tunis, Tunisia, stands out as a top manufacturer and supplier of high-performance metal solutions, providing engineered materials tailored for demanding industrial sectors. Among their impressive product offerings are **Nickel Alloy Hollow Bars**, which are precision-formed tubular profiles celebrated for their exceptional strength and reliability. Mourad Metals merges cutting-edge production techniques with rigorous quality controls to ensure their hollow bars meet global standards and client needs. With a commitment to durability, consistency, and outstanding service, the company supports applications in aerospace, petrochemical, marine, and energy industries, guaranteeing that each Nickel Alloy Hollow Bar delivers robust, long-lasting performance even in tough environments.
**Nickel Alloy Hollow Bars** are generally crafted from high-nickel content alloys, typically featuring **nickel ≥99 %** along with carefully controlled amounts of iron, manganese, silicon, copper, magnesium, and titanium to boost performance. These alloys have a **density of around 8.9 g/cm³** and a **high melting point (~1446 °C)**, ensuring stability at elevated temperatures. They showcase **high tensile strength (∼462 MPa)**, solid yield strength, and impressive **elongation (~45 %)**, striking a balance between strength and ductility. Their hollow design offers a high strength-to-weight ratio while ensuring excellent corrosion resistance in harsh environments. ([semihmetal.com][1])
