5083 H112 Marine Grade Aluminum Coil & Sheet
Product Overview
5083 aluminum is a classic medium-strength Al-Mg corrosion-resistant alloy, known as the standard marine-grade aluminum for harsh saltwater environments. This H112 temper grade is the most widely used structural specification, offering an excellent balance of corrosion resistance, weldability and formability. It can be fabricated by welding, bending, stamping and machining into various structural components, and is the material of choice for shipbuilding, offshore engineering and pressure vessel manufacturing.
Why Choose CNB 5083 Aluminum?
Our 5083 aluminum products are manufactured from high-purity primary ingots with strict control of alloying elements (Mg, Mn, Cr) to ensure consistent corrosion resistance and mechanical properties. We use advanced hot and cold rolling processes to guarantee uniform through-thickness properties and surface quality. Every batch undergoes full mechanical testing and corrosion performance verification to meet international marine and pressure vessel standards.
