Import Aluminum Sheet 5083 — Buy in Bulk from Supplier in Viet Nam

Aluminum Sheet 5083 from Shandong Jintuo Metal Materials Co., Ltd is a 5000-series marine-grade alloy sheet supplied from Viet Nam, with a stated capacity of 1000 tons per month and ISO 9001 certification. The source lists available tempers including O/H111, H112, H12/H22/H32, H14/H24/H34, H16/H26/H36, H18/H28/H38 and H114/H194. The material is stocked in dimensions up to 30 mm thickness, 2200 mm width and 12000 mm length, or as coil. Coil weights run 2-6 tons, with a thickness range of 0.3-14 mm and widths from 50-2000 mm documented across the broader product line.

5083 alloy contains magnesium as its primary alloying element, typically around 4.0-4.9% Mg with manganese additions of 0.4-1.0% Mn, giving it exceptional resistance to seawater corrosion and making it the standard choice for marine applications and cryogenic vessels. The alloy is not suited to heat treatment for strengthening; it derives mechanical properties from strain hardening and solid solution effects. Typical tensile strength for 5083-H321 plate is 275-350 MPa, with yield strength of 125-250 MPa depending on temper and thickness. Weldability is excellent using MIG or TIG with 5183 or 5356 filler wire, though the heat-affected zone experiences some softening.

This grade serves shipbuilders, offshore platform fabricators, pressure vessel manufacturers and chemical tank producers who need Lloyd's or ABS marine approval. The supplier's listed applications include decoration, heat-sink devices, external walls, storage and construction sheets. Payment terms require 30% deposit with 70% balance before delivery. Buyers should confirm temper availability, surface finish (mill, bright or anodised) and whether third-party inspection or mill test certificates are provided. Container loading is offered in 20 ft GP (24-26 CBM), 40 ft GP (54 CBM) and 40 ft HC (68 CBM) formats.

Shandong Jintuo Metal Materials Co., Ltd operates from Liaocheng City, described in its profile as the capital of steel tubes, and positions itself as a large enterprise trading carbon steel, stainless steel, galvanized and colour-coated products, plus copper and aluminium. The supplier tier is marked 'imported' with a 'harbor' trust tier. The response rate sits at 0.00% with zero average response hours recorded, which buyers should treat as a significant engagement risk requiring direct contact verification before reliance.

The company profile emphasises flexible business approaches and management mechanisms aimed at balancing customer service with project owner interests. It does not state factory ownership, specific production equipment, annual revenue, employee count, or named clients. No independent certifications beyond ISO 9001 are listed. The profile does not mention export licence details, bonded warehouse capability, or in-house testing laboratory accreditation. Buyers should verify whether Shandong Jintuo holds direct mill relationships for 5083 or sources through intermediaries, and whether it can provide original mill test certificates with full chemical and mechanical traceability.
