Import 5052/5083/5754/5182 Aluminum Plate/Sheet — Buy in wholesale FOB from Supplier in United States

Zhengzhou Joda supplies Al-Mg alloy plates and sheets across four grades: 5052, 5083, 5754, and 5182, covering tempers from annealed (O) through various H-series strain-hardened conditions including H32, H34, H36, H36, H38, H111, and H112. The 5052 grade offers moderate strength with exceptional formability, bridging properties between 3-series anti-corrosion alloys and higher-strength 5-series grades. 5083 steps up to higher magnesium content for marine and welded structural applications where post-weld strength retention matters. 5754 and 5182 serve automotive body panel and closure applications where dent resistance and paint adhesion are critical performance metrics.

Each alloy responds differently to thermal and mechanical processing. 5052 cannot be strengthened by heat treatment, relying instead on cold work and annealing cycles; its fatigue resistance makes it suitable for pressure vessels and aircraft fuel tanks. 5083's higher magnesium content delivers superior saltwater resistance but requires care in welding to avoid HAZ softening and stress-corrosion susceptibility. 5754 balances strength and press formability for complex automotive stampings. 5182, with slightly higher magnesium than 5754, offers enhanced bake-hardening response and is specified for outer body panels where surface quality after pressing is paramount. Surface finishes available include smooth mill, mirror, and patterned options, with packaging scaled from simple domestic wrap through fumigated wooden pallet export configurations.

The buyer base spans shipbuilders specifying 5083 for hull and superstructure, automotive tier suppliers pressing 5182 and 5754 for closure panels, and general fabricators using 5052 for architectural and transport equipment. Zhengzhou Joda's address is listed as Zhitian Development Zone, Gongyi City, Henan Province, China, though the origin country field states United States, a discrepancy buyers should clarify. No minimum order quantities, pricing, or lead times are disclosed. The supplier cites conformance to ASTM B209 and EN 485 standards, though buyers must verify current test certification and any third-party inspection protocols directly with Zhengzhou Joda.

Zhengzhou Joda operates from Zhitian Development Zone, Gongyi City, Henan Province, China, with the listing origin country field indicating United States. This geographic inconsistency requires direct clarification from the supplier before contracting. The trust tier is 'harbor' with a 0.00% response rate and zero recorded average response hours, which may indicate a passive listing or limited active engagement. No information on workforce size, production capacity, year of establishment, or financial turnover is available in the source profile.

The supplier's product focus is on rolled Al-Mg alloy plate and sheet with multi-alloy stocking or mill-direct supply capability across the 5052-5182 range. ASTM B209 and EN 485 are cited as conformance standards, though the specific scope of any quality system certification is not detailed. Buyers should request evidence of alloy-specific testing capability, particularly for mechanical property verification and ultrasonic inspection of thicker 5083 plate. The address structure suggests proximity to Zhengzhou's industrial corridor, with potential logistics access to Xinxiang or Zhengzhou airport freight terminals, though this requires confirmation.
