Aluminium Coil Tubing is essentially composed of high-purity aluminium alloy, typically containing elements like magnesium, silicon, and copper to improve strength and corrosion resistance. Such a combination creates a lightweight yet robust framework with great thermal conductivity and flexibility. The mechanical properties have a tensile strength that is usually between 90 to 250 MPa, varying with the grade of the alloy, with enhanced elongation and fatigue resistance. Its exceptional corrosion resistance, along with non-magnetic characteristics, qualifies it for diverse industrial usages where performance, as well as longevity, is critical.
