5052 Aluminum Alloy Composite Stainless Steel Foil

5052 Aluminum Alloy Composite Stainless Steel Foil is a bimetallic layered composite material. It uses 5052 rust-resistant aluminum alloy as the surface/inner layer, combined with 304 or 316L stainless steel foil as the base layer. Atomic-level bonding is achieved through a hot-rolling composite + cold-rolling finishing process, resulting in a bond without adhesives or delamination, and with high interfacial bonding strength. It combines the low density, high thermal conductivity, and excellent corrosion resistance of aluminum alloy with the high strength, tensile strength, high-temperature resistance, and deformation resistance of stainless steel.

 Precision Electronics and Electrical Industry: Used in mobile phone shielding covers, battery tabs, flexible circuit board substrates, electrical insulation gaskets, electromagnetic shielding foils, and heat sink foils, addressing the needs for thermal conductivity, shielding, insulation, and lightweighting, improving the stability and heat dissipation efficiency of electronic equipment.

 New Energy Equipment: Heat dissipation foil for new energy vehicle power batteries, thermal insulation shielding layers for energy storage equipment, conductive gaskets for photovoltaic modules, and insulating shielding materials for charging piles; high temperature resistance and corrosion resistance, suitable for the long lifespan and high safety requirements of new energy products.

 Chemical and Corrosion Protection Engineering: Anti-corrosion coating foil for chemical pipelines, sealing gaskets for storage tanks, linings for desulfurization equipment, and seals for seawater desalination plants; acid and alkali resistance and salt spray resistance, solving corrosion problems in chemical equipment and extending equipment lifespan.

 Transportation and Shipbuilding: Anti-corrosion foil for marine interiors, lightweight automotive parts, high-speed rail sealing gaskets, and precision aerospace components; lightweight, high strength, and resistant to marine corrosion, suitable for the weight reduction and durability requirements of transportation equipment.

 HVAC and Heat Exchange Equipment: Air conditioner evaporators, condenser fins, heat exchanger foils, heat transfer sheets for waste heat recovery equipment. High thermal conductivity and corrosion resistance improve heat exchange efficiency and reduce energy consumption.

Q1: Is this composite foil adhesive-bonded or rolled? Will it delaminate?

A: This product uses a hot-rolled composite process without any adhesives. The aluminum and steel layers are atomically bonded, resulting in extremely high bonding strength. Delamination and cracking will not occur during normal bending, stamping, and rolling processes. Except for extreme damage, it is safe for normal use.

Q2: Can you customize special thicknesses and widths? What is the minimum order quantity?

A: We support full-specification non-standard customization, starting from 0.03mm in thickness and 10mm in width. The minimum order quantity for small batch samples of standard specifications is 5KG, and the minimum order quantity for large-scale production is 50KG.

Q3: Can the ratio of the 5052 aluminum layer to the stainless steel layer be adjusted?

A: Yes, the proportion of aluminum layer can be adjusted between 30% and 70% as needed. We can also customize a three-layer composite structure (aluminum-steel-aluminum) to suit different strength, thermal conductivity, and corrosion resistance requirements. Parameter solutions can be provided before placing an order.
