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

Gongyi Hongma Trade Co., Ltd supplies aluminum strip in Aluminum Alloy 3003 and 1100 Series, grades widely employed where corrosion resistance and formability are essential. The listing cites additional availability of 1050, 1060, and 5052 grades, expanding the range to cover applications from pure aluminum deep drawing to medium-strength marine-grade forming. The 3003 alloy, with manganese as the primary alloying element, offers approximately 20 percent greater strength than 1100 while retaining excellent workability, making it suitable for heat exchangers, cooking utensils, and chemical handling equipment. The 5052 grade, with magnesium addition, provides superior corrosion resistance in saltwater environments and is the strongest non-heat-treatable alloy in common strip supply.

Typical mechanical properties for 3003-H14 strip include ultimate tensile strength of 145-195 MPa, yield strength of 125-165 MPa, and elongation of 1-6 percent depending on orientation and thickness. The 1100-O annealed condition exhibits UTS of 75-105 MPa with elongation of 35-45 percent, optimal for severe forming operations. Standard industry thickness for general-purpose strip ranges from 0.2 mm to 6.0 mm, with widths from 8 mm to 500 mm, though the supplier does not confirm stock dimensions and these must be requested. Thermal conductivity is approximately 193 W/m·K for 3003 and 218 W/m·K for 1100, relevant for heat transfer applications. Electrical conductivity of 1100 is 59 percent IACS, making it suitable for busbar and transformer winding applications where specified.

Primary application sectors for this product line include automotive manufacturing (baffles, trim, heat shields), construction (flashing, fascia, decorative trim), electrical engineering (winding strip, busbar material), and packaging (closure stock, can body tab). The 5052 grade specifically serves marine superstructure, fuel tankage, and pressure vessel applications. Buyers targeting automotive or aerospace supply chains should confirm material certification to IATF 16949 or AS9100 requirements if applicable, as the listing does not state quality system accreditation. Standard export packaging is mentioned without specification; buyers should confirm coil orientation, protective interleaving, and moisture barrier provisions. The supplier's location in Gongyi, Henan Province, positions it within China's central aluminum processing belt with access to primary metal supply from regional smelters.

Gongyi Hongma Trade Co., Ltd is located at Dufu Road, Gongyi, Zhengzhou 451250, Henan Province, China. The supplier carries a 'harbor' trust tier and 'imported' supplier tier classification. The response rate is recorded at 0.00 percent with zero average response hours, suggesting limited platform engagement or a newly established profile. The company name includes 'Trade Co., Ltd', indicating potential trading company rather than direct manufacturer status, though this requires confirmation. No information regarding year of establishment, registered capital, employee count, or factory ownership is provided in the source material.

The listing presents the company as serving automotive, construction, electrical, and packaging industries with multiple aluminum alloy grades. However, no production capacity figures, export volumes, specific clientele, or quality management certifications are stated. The location in Gongyi places the company near significant aluminum processing capacity, but proximity does not confirm manufacturing capability. Buyers should conduct due diligence including business licence verification, factory audit if manufacturing is claimed, and reference checks with existing customers before committing to volume orders.
