Product Introduction
Aluminum steel explosion proof composite plates are lightweight, multi-functional bimetallic metallurgical composite panels manufactured using a high-energy explosion cold welding process. This process overcomes the technical bottlenecks of the large melting point difference and poor weldability between aluminum and steel through high-speed explosion-driven collisions, achieving complete metallurgical bonding at the interface. The product combines the lightweight, excellent electrical and thermal conductivity, and atmospheric corrosion resistance of aluminum with the high strength, ease of welding, and cost-effectiveness of steel. Using aluminum only for functional surfaces and steel for the main body, material costs can be reduced by 30%-50% compared to pure aluminum panels. It also solves the industry problems of easy cracking and low bonding strength when directly welding dissimilar metals like aluminum and steel. Widely used in new energy vehicle battery trays, rail transit vehicle body structures, power conductive busbars, heat exchange equipment, and corrosion-resistant transition components, it is a core composite structural material for lightweighting, cost reduction, and upgrading in the industrial sector.

Product Features and Applications
Product Advantages
Explosive cold welding achieves atomic-level metallurgical bonding, perfectly avoiding the problem that aluminum and steel cannot be welded due to their huge difference in melting points. The interface bonding strength far exceeds that of rolling and brazing composites, and there is no delamination after bending, stamping, and stretching.
The aluminum layer provides corrosion resistance, electrical conductivity, and heat dissipation, while the steel layer provides structural load-bearing capacity. Under the same strength, it is 30%+ lighter than pure steel plates and more than twice as strong as pure aluminum plates, balancing lightweight and structural safety.
Only the functional contact surfaces use aluminum, while the main body uses low-cost steel. Compared with pure aluminum plates, it saves 30%–50% of material costs while achieving the same performance, significantly reducing the overall cost of the equipment.
It can perform deep processing such as bending, stamping, rolling, CNC machining, and welding, and supports the production of various components such as battery trays, housings, transition joints, and heat exchange plates.
It possesses multiple properties such as resistance to atmospheric corrosion, electrical conductivity, thermal conductivity, and electromagnetic shielding, making it suitable for the diverse needs of various industries, including new energy, transportation, power, and chemical industries.
Application Areas
New energy industry: power battery trays/shells, energy storage battery structural components, heat dissipation and conductive base plates.
Rail transit: lightweight structural components for car body, door/floor frame, conductive transition joints.
Power industry: conductive busbar transition busbars, transformer heat dissipation components, photovoltaic conductive supports.
Heat exchange equipment: plate heat exchangers, radiators, cooler liners, chemical heat exchange components.
Chemical corrosion protection: reactor lining, pipe transition joints, structural components for atmospheric corrosion environments.
Marine Engineering: Marine superstructure, corrosion-resistant and conductive transition components for offshore platforms.

Professional Consultation Q&A
Q1: What international standards do your aluminum-steel explosion-proof composite panels meet?
A1: Our aluminum cladding strictly adheres to ASTM B209 standards, our steel substrate conforms to ASTM A36 / ASTM A516 / ASTM A240 standards, and the production of our composite panels complies with ISO 15614-12 explosive welding specifications. Each batch of products comes with an EN 10204 3.1 material inspection certificate.
Q2: What is the difference between exploded composite aluminum steel sheet and rolled composite aluminum steel sheet?
A2: Explosive bonding forms a complete metallurgical bond with high shear strength. It will not delaminate after bending, stamping, and deep drawing, making it suitable for load-bearing and deep processing applications. Rolled bonding, on the other hand, only achieves a mechanical bond with lower strength. It is prone to peeling under stress and is mostly used for simple decoration or flat lining applications.
Q3: Which grade of aluminum should be used for the tray of new energy batteries?
A3: F5052 aluminum-magnesium alloy is an ideal choice for battery trays, possessing high strength, excellent corrosion resistance, and good formability. For higher conductivity requirements, 1060 pure aluminum can be used for the conductive contact surface.
Q4: Can aluminum-steel composite panels be bent, stamped, and welded?
A4: Yes. Our exploded composite panels have a stable metallurgical bonding interface and can pass a 180° cold bending test without cracking or delamination. We support secondary processing such as stamping, CNC drilling, and welding according to customer drawings.
