Import 3105 Aluminum Alloy — Buy in wholesale FOB from Supplier in China

3105 aluminum alloy from Tradematt (henan) Industry Co., Ltd is an Al-Mn wrought alloy with approximately 98% aluminum content, classifying it within the pure aluminum alloy family with strength slightly above 1xxx series grades. The material cannot be strengthened by heat treatment, relying instead on work hardening through cold rolling and forming to achieve desired mechanical properties. Tradematt supplies this alloy in sheet, coil, and plate forms, with standard tempers including H24 and O annealed conditions that directly influence machinability and forming behaviour.

The alloy's microstructure delivers excellent corrosion resistance in atmospheric and marine environments, alongside superior formability that supports deep drawing, spinning, and complex stamping operations. Weldability is rated excellent across all conventional arc and resistance welding processes, though post-weld annealing may soften heat-affected zones. Machining requires flood lubrication due to the alloy's tendency to gall and load cutting tools, with harder tempers offering improved chip formation over fully annealed stock. Standard surface finishes include mill finish, bright finish, and embossed patterns for architectural applications.

Primary applications span residential siding and soffit panels, mobile home cladding, rainware systems, screw closures and bottle caps, lamp headstocks, venetian blind slats, and general sheet metal fabrications. The alloy's combination of moderate strength, corrosion immunity, and cosmetic acceptance after anodising makes it a standard specification for building products manufacturers and packaging closure producers. Buyers should confirm temper availability, coil inner diameter, and edging requirements directly with Tradematt, as these parameters determine downstream processing compatibility and yield rates.

Tradematt (henan) Industry Co., Ltd maintains its registered office at Shenglong Plaza in Zhengzhou's Zhengdong New District, within Henan Province's industrial corridor. The company holds a Harbor trust tier classification on the platform, with a response rate currently showing 0.00% and average response hours at zero, indicating no inbound enquiry activity recorded or limited platform engagement at present. No verification of third-party audit, ISO certification, or export licence specifics appears in the available supplier profile.

The listing focuses on 3105 aluminum alloy supply in multiple semis forms, with particular emphasis on deep-drawn applications where the alloy's formability advantage over 1xxx grades delivers value. Tradematt does not disclose production capacity, annual turnover, employee count, or key account relationships in the visible profile. Buyers should request a current mill test certificate, temper certification to EN 485 or ASTM B209 as applicable, and evidence of export documentation capability before committing to trial orders.
