Aisha Nickel Alloys is a reliable manufacturer and supplier of Inconel 718 Tubing in Muscat, Oman. We provide high-performance nickel alloy tubing engineered for applications where exceptional strength, fatigue resistance, and temperature stability are essential. Our Inconel 718 tubes are manufactured to international standards and thoroughly inspected to ensure consistent quality and long service life. Serving industries such as aerospace, oil & gas, power generation, and advanced engineering, we focus on delivering tubing solutions that engineers can trust, supported by technical expertise and responsive customer service.
Inconel 718 tubing is made from a nickel-chromium alloy strengthened through precipitation hardening with niobium and molybdenum. This composition provides exceptionally high tensile and yield strength, outstanding fatigue and creep resistance, and excellent toughness. The alloy maintains stable mechanical properties over a wide temperature range, from cryogenic conditions to elevated temperatures. Inconel 718 also offers good resistance to corrosion and oxidation, making it suitable for high-stress and high-temperature tubing applications.
