Aluminum alloy 5052 Aluminum Coil for Automotive Fuel Tanks | Thickness 1.0–3.0 mm | Width 800–1600 mm | Oil-free & Clean Surface

Introduction                                                

The 1.0–3.0 mm 5052 aluminum coil (oil-free clean surface, superior fatigue strength) is the global industry standard for automotive fuel tanks, diesel tanks, filler necks, fuel delivery modules and structural enclosures in both internal combustion engine (ICE) vehicles and electric vehicles (EV battery trays with fuel-cell variants).

With Mg content 2.2–2.8%, 5052 (H32/H34 temper) is classified as the highest-strength non-heat-treatable alloy suitable for deep-drawn & welded fuel tank applications and offers:

Outstanding resistance to road salt, humidity & automotive fluids

High fatigue strength for vibration & pressure cycling

Oil-free & ultra-clean surface → direct use in high-purity welding & adhesive lines

Significant weight reduction vs steel tanks → improved fuel efficiency & range

Surface features:Oil-free degreased & chemically cleaned → no rolling lubricants or residues,Optional chromate-free passivation or anti-fingerprint nano-coating

FAQ (USA/Europe/Middle East/Asia Buyers)

Q1: Why choose 5052 over 3003 or 5754 for automotive fuel tanks & battery enclosures?

A: 5052 offers significantly better corrosion resistance (especially road salt & coastal) than 3003 and is more cost-effective & easier to deep-draw than 5754. It is the marine-grade sweet spot for fuel tanks & battery trays exposed to humidity, salt & vibration.

Q2: How clean is the “oil-free” surface & is it ready for direct welding/adhesive bonding?

A: Degreased & rolling oil residue < 0.01 mg/m². Meets high-purity automotive & battery assembly requirements. We provide surface cleanliness test reports (ASTM D4940 equivalent).

Q3: Can the sheet be deep-drawn or impact extruded for complex fuel tank shapes?

A: Yes — 5052 has excellent formability (elongation >12–18%). Optimized for deep-drawn & impact extruded tank shells. Forming limit diagrams (FLD) & trial shells available.

Q4: Minimum order quantity & lead time for custom width or passivation?

A: MOQ 3–5 tons (depending on width/thickness); standard specs 15–25 days; custom width or chromate-free passivation 25–35 days. Sample coils free with freight collect.

Q5: How does 5052 perform in salted-road & high-humidity environments?

A: Excellent — passes 3000–5000 h salt-spray & humidity aging tests. No pitting or white rust in automotive underbody conditions. Salt-spray & road exposure data available.

Q6: Is 5052 suitable for structural battery trays in EVs?

A: Yes — high rigidity & fatigue strength allow thinner gauges for weight-critical structural components. Weldability & crash performance data provided.
