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

Gongyi Hongma Trade Co., Ltd markets aluminum coil in 1100, 3003, 5052, and 6061 alloy series, with thickness spanning 0.012mm to 10.0mm. The 6061 addition distinguishes this offering, as it is a structural grade with magnesium and silicon addition, heat-treatable to T6 temper, and suited to applications where weldability and medium-to-high strength are required alongside corrosion resistance. The supplier highlights roofing, cladding, heat exchangers, automotive body panels, and packaging as principal applications, with standard export packaging in eye-to-sky or eye-to-wall orientation.

The 6061 alloy in this product range contains 0.8-1.2% magnesium and 0.4-0.8% silicon, with copper, chromium, and zinc as trace elements. In T6 temper, it achieves typical yield strength of 240 MPa and tensile strength of 290 MPa, substantially exceeding 3003-H14 values. The 0.012mm minimum thickness suggests foil-gauge capability, likely for flexible packaging or transformer winding applications where high purity and thin-gauge control are essential. For structural applications, 6061-T6 offers excellent machinability and accepts anodizing well, though it is less formable in T6 than in T4 or O conditions. Typical industry practice specifies 6061-T6 for truck and marine frames, railway cars, and structural tubing, while 3003 dominates non-structural heat transfer and architectural applications.

Purchasers include aerospace subcontractors, automotive tier-one suppliers, construction material distributors, and packaging converters. The Henan location places Gongyi Hongma inland, with Zhengzhou as the nearest major logistics hub, approximately 50km from the supplier address. Buyers should clarify whether pricing is ex-works Gongyi or includes delivery to a port such as Qingdao or Lianyungang for containerized export. The listing does not state MOQ, lead time, or certification details, so direct negotiation is necessary. For 6061 structural grades, insist on hardness testing and ultrasonic inspection certificates if the application involves load-bearing or safety-critical components.

Gongyi Hongma Trade Co., Ltd is located on Dufu Road, Gongyi, Zhengzhou 451250, Henan Province, China. The supplier holds an imported tier designation and harbor trust tier on the platform, with a response rate of 0.00% and no recorded average response hours. This profile suggests limited platform-mediated communication history, so buyers should establish direct contact through email or telephone channels provided in the listing rather than relying on platform messaging for time-sensitive negotiations.

The company offers aluminum coil across an unusually wide thickness range, from foil-gauge 0.012mm to heavy plate 10.0mm, and includes 6061 structural alloy alongside more common 1100, 3003, and 5052 grades. No factory ownership, production capacity, year of establishment, employee count, or revenue is disclosed. The listing does not specify ISO certification, laboratory accreditation, or third-party audit status. Buyers should request factory audit reports, quality management system certificates, and sample mill test certificates before committing to volume orders. The Henan location is China's largest aluminum production province, which may indicate proximity to primary smelters, though this should be verified directly with the supplier.
