Overview
5083 aluminum alloy is an Al-Mg series alloy renowned for its exceptional weldability, corrosion resistance, and processing performance. Delivering excellent comprehensive performance at medium strength levels, it is the ideal material for manufacturing liquid tankers and cryogenic pressure vessels. Particularly in the transportation of ultra-low temperature media such as LNG and long-haul freight in coastal/salt-spray environments, 5083 plate is the industry's preferred choice due to its structural stability and environmental adaptability.
Specification
Alloy: 5083
Temper: O, H111
Thickness: 3-12mm
Width: 1000-2600mm
Length: 2000-12000mm
Feature
Excellent Low-Temperature Toughness: Performs reliably at LNG temperatures (-162 °C), maintaining both strength and ductility, making it ideal for cryogenic transport and storage.
Outstanding Corrosion Resistance: High magnesium content delivers strong resistance to salt spray and marine atmospheres, significantly reducing long-term maintenance costs.
Excellent Weldability: Supports various processes including TIG, MIG, gas welding, and spot welding. The welded joints offer high strength and good elongation, capable of withstanding vibrations and impacts during tanker operation.
Lightweight Design: Higher strength-to-weight ratio than steel reduces vehicle dead weight and increases payload capacity, improving transport economics.
Recyclable & Sustainable: Fully recyclable aluminum supports green manufacturing and lifecycle cost efficiency.
Application
5083 aluminum plate is primarily used for tank bodies, tank heads, baffles, bulkheads, and manhole covers, and can also be applied to high-stress components such as level gauges and air inlets.
