Import 5086 Aluminum Plate For Machine Accessories — Buy in wholesale FOB from Supplier in China

5086 aluminum plate for machine accessories is a high-magnesium, non-heat-treatable wrought alloy supplied in plate form with thickness exceeding 6 mm. The material contains 3.5% to 4.5% magnesium by weight, with manganese at 0.2% to 0.7% and chromium at 0.05% to 0.25%, which together provide solid solution strengthening and corrosion resistance without requiring thermal treatment. Its strength sits above 5052 alloy and marginally below 5083, placing it in a practical middle band for structural machine components where welding and seawater exposure matter. This listing sources from a major Chinese rolling mill in Gongyi City, Henan Province, with the plate produced to ASTM B209 and EN 485 dimensional and mechanical standards.

The alloy's microstructure is characterised by a stable Al-Mg matrix with fine intermetallic dispersoids from the manganese and chromium additions. These elements refine grain structure and inhibit recrystallisation during hot rolling, which helps maintain mechanical anisotropy favourable to plate applications. Typical tensile strength for 5086-H32 plate ranges from 275 to 350 MPa, with yield strength of 145 to 250 MPa depending on temper and cross-rolling practice. Elongation at break typically falls between 10% and 14% in longitudinal orientation. The material cannot be strengthened by precipitation hardening, so cold work and solid solution effects are the only strengthening mechanisms available to the producer.

Machine accessory applications include precision jigs,夹具, structural frames for automated production lines, conveyor components, and mounting bases for heavy equipment where atmospheric or process corrosion is a risk. The alloy's excellent arc and MIG weldability, using 5356 or 5183 filler wire, allows fabricated assemblies without post-weld heat treatment. Buyers in industrial machinery, semiconductor equipment, and food processing sectors value the combination of low density, good machinability in H116 or H321 tempers, and resistance to chloride-containing environments. For import trade, confirm temper designation, flatness tolerance per EN 485-4, and whether mill test certificates include ultrasonic testing for internal discontinuities.

Henan Mingtai Al. Industrial Co., Ltd operates from Gongyi City in Henan Province, China, with this listing carrying a Harbor trust tier designation and a published response rate of 0.00% with zero average response hours recorded. The supplier address is confirmed as Gongyi City, Henan Province, China, placing it within one of China's concentrated aluminium processing corridors with access to bauxite feedstock, thermal power, and inland logistics networks. The company presents itself as a production-oriented supplier rather than a pure trader, with the listing emphasising mill-level specification control and conformance to ASTM and European norms.

What the profile does not state is equally relevant: no confirmed employee count, production capacity, ISO certification numbers, or named clients appear in the extracted data. The response rate metric suggests either a new listing, a dormant account, or a data collection gap that buyers should factor into due diligence. There is no information about export licence status, whether the company holds ASME or NORSOK approvals for pressure equipment, or its history of supplying European or North American markets. Buyers should verify directly whether the company operates its own rolling mill or sources through toll arrangements, and whether it can supply third-party inspection certificates from agencies such as SGS or TUV.
