Import 7050 Aluminum Sheet/Plate — Buy in wholesale FOB from Supplier in China

7050 aluminum sheet and plate is a high-strength, heat-treatable alloy in the Al-Zn-Mg-Cu system, supplied with nominal composition of zinc 5.7-6.7%, copper 2.0-2.6%, magnesium 1.9-2.6%, and balance aluminum. Detect Metals Co., Ltd. supplies this material in T7451 temper, which delivers superior stress corrosion cracking resistance and fracture toughness compared to legacy 7075-T6, particularly in thick sections from 3 to 6 inches (76 to 152 mm). The alloy is specified for wing skins, fuselage frames, and other primary structural components in commercial and military aerospace programs, and trades globally under HS code 7606.

The T7451 temper designation indicates solution heat treatment, stress relief by stretching, and precipitation hardening to a condition optimised for resistance to exfoliation and intergranular corrosion. In the 3-6 inch thickness range, 7050-T7451 maintains more uniform through-thickness properties than 7075 due to lower quench sensitivity, a consequence of its copper and zinc balance. Typical tensile strength in this temper ranges from 510 to 550 MPa ultimate, with yield strength of 460 to 490 MPa and elongation of 8-10% in longitudinal orientation. Fracture toughness (K_IC) values are typically 30-40 MPa(m)^0.5, depending on specimen orientation and testing standard.

Primary buyers include aerospace sub-tier manufacturers, defence contractors, and precision machine shops producing landing gear components, bulkheads, and structural brackets. Procurement typically requires material certification to AMS 4050 or customer-specific variants, with full traceability back to the mill source. Detect Metals Co., Ltd. sources from Chinese mill production; buyers should verify whether the supplied material carries NADCAP-approved testing, mill test certificates to EN 10204 3.1 or 3.2, and conformance to specific OEM material specifications such as Airbus or Boeing process standards.

Detect Metals Co., Ltd. is headquartered in Tianjin, China, postal code 300400. The company holds a harbor trust tier on the platform. Its response rate is recorded at 0.00% with an average response time of 0 hours, indicating no reliable platform-mediated communication channel. Buyers should obtain direct contact details, preferably a dedicated sales engineer familiar with aerospace material certification, before relying on platform inquiry tools.

The supplier's profile focuses on aluminum alloy plate distribution, with explicit positioning in the aerospace and defence supply chain. No manufacturing facility details, ISO/AS9100 certification status, or export licence specifics are stated. The listing does not indicate whether Detect Metals stocks material in Tianjin or operates on mill-direct drop-ship arrangements. Importers should request evidence of supply chain traceability, including mill name, heat number protocol, and whether the company holds OEM-approved vendor status for any aerospace prime contractor.
