5052 Aluminum Coil

5052 aluminum coil is the highest-strength common sheet alloy in the 5xxx series, built on a 2.5% Mg + 0.25% Cr composition. Where 3003 aluminum coil handles general fabrication, 5052 aluminum coil is specified when the part meets salt water, fuel, pressure, or fatigue loading - marine structures, pressure vessels, fuel tanks, and automotive structural panels.

The chromium addition in 5052 aluminum coil controls grain structure during annealing, while magnesium provides solid-solution strengthening. H32 temper - strain-hardened and stabilized - delivers tensile 210–260 MPa and yield ≥150 MPa, roughly double the strength of 1100 at comparable corrosion resistance. The magnesium level (2.2–2.8%) sits below the stress-corrosion-cracking threshold that affects higher-Mg alloys like 5083, making 5052 aluminum coil a stable choice for welded structures exposed to wet service.

Functional advantages: Approximately 2× the yield strength of 1100/3003 at similar corrosion performance · Excellent weldability by GMAW/GTAW · Good formability in H32 for bending and forming · Suitable for service from −196°C to 120°C.

Henan Yongsheng Aluminum Industry Co., Ltd. produces 5052 aluminum coil at its Gongyi, Henan facility - a site within China's largest aluminum sheet and strip processing cluster, with 25 years of export experience.

5052 aluminum coil from Yongsheng is rolled from prime Al-Mg stock with controlled chromium addition. Key controls:

• Composition verification - Mg and Cr checked against 5052 range on every heat
• Temper stabilization - H32 properties verified by tensile and yield testing per lot
• Flatness and edge quality - measured inline to support downstream welding and forming
• Salt-spray sampling - retained coil samples available for buyer-side corrosion testing
• Slitting to customer widths, cut-to-length processing, and PVC film application are performed in-house for 5052 aluminum coil orders.

5052 aluminum coil is specified across four load-bearing and corrosion-critical environments where 3003 or 1100 would be under-strength or under-durable.

Marine & Offshore Structures. The defining application for 5052 aluminum coil is boat hulls, decks, bulkheads, wheelhouse panels, portholes, and small marine craft. 5052 is recognized as a marine-grade aluminum: salt-spray resistance exceeds 1,000 hours in marine atmosphere, outperforming 5005 in seawater exposure. 5052 aluminum coil is also used for offshore platform components, dock fittings, and pipe covers where long-term salt exposure is unavoidable.

Pressure Vessels, Tanks & Fuel Systems. 5052 aluminum coil in H32 is listed under ASTM B209 for pressure vessel and fuel-tank service, and is permitted in cargo-tank construction referencing the ASME Code. Applications include stationary fuel tanks, road tanker shells, oil and fuel tubing, and air receiver bodies. 5052 aluminum coil is also used for LNG-adjacent cold-service components, since strength rises at low temperature rather than embrittling.

Automotive & Transportation Panels. 5052 aluminum coil serves as body panels, truck side panels, semi-trailer skins, shock-absorber components, and heat shields. The strength-to-weight ratio of 5052 aluminum coil enables gauge reduction versus steel while maintaining structural integrity under road vibration; its fatigue limit supports long-cycle service in suspension and chassis-adjacent parts.

Industrial Equipment & Enclosures. 5052 aluminum coil is fabricated into chemical equipment housings, GIS enclosures, silo and flange material, refrigerator liners, and storm shutters - parts that need weldability plus resistance to mildly corrosive media.

• Temper: H32 for the majority of 5052 aluminum coil orders - the practical balance between strength and forming. H34/H36 for higher-strength panels; O for severe forming; H112 for elevated-temperature or welded applications.
• Thickness & width: 0.30–6.0 mm; slit to 20–2,600 mm. Tighter tolerances quoted against buyer drawing for 5052 aluminum coil.
• Surface: Mill finish, stucco embossed, or PVC protective film. 5052 aluminum coil can be supplied degreased for coating, anodizing, or painting lines.
• Coil parameters: ID 405/505/605 mm; coil weight up to 2,000 kg.
• MOQ: 2–5 MT per size for 5052 aluminum coil; trial coils considered.

Pre-sale support for 5052 aluminum coil covers temper selection and weldability review: send the part drawing, service environment (marine, fuel, pressure, road), and joining method, and the team confirms whether H32, H34, or O condition fits. Mill Test Certificate (EN 10204 3.1) with Mg/Cr composition and mechanical properties accompanies every 5052 aluminum coil shipment. Salt-spray test reports and retained samples are available for buyer qualification. A 12-month quality response window applies to 5052 aluminum coil with batch traceability through coil ID. Export documents and third-party inspection (SGS, BV) coordination are handled in-house. Payment: T/T, L/C at sight. 

5052 aluminum coil is eye-protected and edge-ringed, wrapped in plastic film and craft paper, then secured on wooden pallets or in plywood cases. Labels show alloy, temper, thickness, width, coil ID, heat number, and net weight.

A 20′ container loads 18–22 MT of 5052 aluminum coil. Primary loading port: Qingdao; Tianjin and Shanghai on request. FOB, CFR, and CIF accepted. Lead time: 7–15 days for stock H32 specifications; 15–25 days for custom 5052 aluminum coil production.
