Import Aluminum Coil Roll 5052 — Buy in wholesale FOB from Supplier in China

Chongqing Exceed Metal Co., Ltd produces aluminum coil roll in 5052 alloy, a non-heat-treatable Al-Mg alloy with nominal composition 2.2-2.8% magnesium, 0.15-0.35% chromium, and alloyed aluminium. The mill offers this product in tempers O/H111, H112, H12/H22/H32, H14/H24/H34, H16/H26/H36, and H18/H28/H38, with thickness spanning 0.1 mm to 7.0 mm and maximum width of 2630 mm. This width capability exceeds many standard mills and suits buyers requiring wide-format coil for trailer siding, large tank fabrication, or architectural cladding without longitudinal welding.

The 5052 alloy's magnesium content provides exceptional resistance to marine and industrial atmospheres, while chromium addition controls grain structure and enhances stress corrosion cracking resistance. H32 temper, strain-hardened and stabilized by low-temperature thermal treatment, delivers target tensile strength of 230-280 MPa with yield strength of min 195 MPa per ASTM B209. The H34 temper increases strength further to 255-305 MPa tensile with min 230 MPa yield, traded against reduced formability. Typical elongation ranges 10-14% for H32 and 8-12% for H34 in 50 mm gauge length, values buyers should verify on mill test certificates for their specific order.

Primary applications include printing plate bases, anti-skid tread plate substrates, lid stock for food and beverage containers, industrial equipment panels, storage cabinets, and lighting reflectors. The 5052-H32 variant particularly suits welded structures in salt-water environments such as small boat hulls and marine superstructures, where its fatigue limit of approximately 115-140 MPa (fully reversed loading, typical) outperforms many comparable alloys. Chongqing's inland location in Shapingba District offers rail or river-transport connections to Chongqing Port on the Yangtze River for export consolidation, though buyers should confirm the supplier's preferred export routing and container loading facilities.

Chongqing Exceed Metal Co., Ltd is located at 6-23, Building 2, No. 21 Xishuang Avenue, Shapingba District, Chongqing City, 400030, China. The company holds a Harbor trust tier and, like the previous listing, shows a 0.00% response rate with zero average response hours on the platform, suggesting limited active engagement or incomplete data capture. Its specialisation appears concentrated on flat rolled aluminum products rather than diversified metal trading.

The supplier's profile does not indicate factory ownership, production capacity, number of employees, annual revenue, specific quality certifications, or notable client references. Its stated product range covers multiple alloy series (1xxx, 3xxx, 5xxx) with emphasis on width capability up to 2630 mm, which may indicate slitting and processing investment or partnership with a wide mill. Buyers should independently verify whether Chongqing Exceed Metal operates its own rolling mill, functions as a processor/reseller, or maintains exclusive mill relationships, as this affects quality accountability and pricing structure.
