Aluminium Boiler Tubing generally comprises high-purity aluminium alloys like 1060, 3003, or 6061 with superior thermal conductivity and corrosion resistance. Silicon, magnesium, and manganese can be the major alloying elements that contribute to strength and weldability. Mechanical properties are grade-dependent, but typically include tensile strength 150–290 MPa, yield strength 130–240 MPa, and 10–20% elongation. Tubes are good in formability, have lightweight properties, and have a high thermal efficiency with these characteristics making them fit for high-performance boiler plants and heat exchange procedures in harsh environments.

Aluminium Boiler Tubing is generally applied in industries requiring efficient heat transfer, corrosion resistance, and light materials. Some of these applications are power generation, chemical processing, marine engineering, food and beverage, and heating, ventilation, and air conditioning systems. The tubing is a crucial element in heat exchangers, condensers, economizers, and boilers because it has superior thermal conductivity. Its high-temperature corrosion and oxidation resistance also qualify it for use in industrial boilers and fluid systems for extended periods. Aluminium‘s reusability and reduced weight also contribute to it being a favored option in green and energy-saving engineering solutions.
