Two Popular Thickness: 4mm and 6mm Aluminum Sheet
Nov 05 25
In the global aluminum sheet market, 4mm and 6mm thick aluminum sheets consistently hold a significant position, especially favored by overseas customers. This is not accidental, but stems from the stringent considerations of overseas markets regarding product performance, application adaptability, and overall cost, requirements that 4mm and 6mm aluminum sheets precisely meet.
4mm Aluminum Sheet
1. Core Advantages
The most significant advantage of the 4mm aluminum sheet lies in the balance between lightweight and good rigidity. Compared to thicker aluminum sheets, it is lighter, effectively reducing the overall structural weight and decreasing costs and difficulties during transportation and installation.
Simultaneously, the 4mm thickness ensures sufficient rigidity, resisting deformation under pressure and external forces, meeting structural support requirements in most scenarios. Furthermore, 4mm aluminum sheets possess excellent processing performance, easily achieving cutting, bending, welding, and surface treatments (such as spraying and anodizing) with high precision, meeting the stringent requirements of overseas customers for product detail.
2. Typical Application Scenarios
Architectural Decoration: 4mm aluminum sheets are widely used in exterior wall, interior ceiling, and curtain wall decoration abroad. They can be processed into various uniquely shaped decorative panels, and after special surface treatment, they can present rich colors and textures, matching different architectural styles. For example, many modern apartment buildings in Europe commonly use 4mm anodized aluminum sheets as exterior wall decoration materials, which are both beautiful and durable.
Transportation: 4mm aluminum sheets are an ideal choice in the manufacture of RVs and light truck bodies. RVs have extremely high requirements for weight control, and the lightweight properties of 4mm aluminum sheets effectively improve the RV's range; at the same time, their good corrosion resistance can cope with the complex climates of different regions, ensuring the long-term stable use of the vehicle body.
Electronic Equipment Housings: For some medium-sized electronic devices, such as industrial control displays and small server chassis, 4mm aluminum plates provide sufficient protection without adding excessive weight, facilitating movement and installation. Foreign electronic equipment manufacturers prioritize durability and portability, and 4mm aluminum plates perfectly meet this requirement.
6mm Aluminum Plates
1. Core Advantages
The core competitiveness of the 6mm aluminum plate lies in their higher strength and excellent durability. The thicker thickness makes them far superior to 4mm aluminum plates in impact and bending resistance, able to withstand greater loads and external impacts, and less prone to damage during long-term use.
Furthermore, 6mm aluminum plates offer better heat and sound insulation, providing better environmental protection for application scenarios. Simultaneously, they also possess good corrosion resistance, maintaining stable performance in harsh environments such as humidity and acid/alkali conditions, extending product lifespan.
2. Typical Application Scenarios
Industrial Equipment Platforms and Frames: In overseas factories, many industrial equipment operating platforms and equipment frames utilize 6mm aluminum plates. For example, in automated production lines, conveyor platforms need to bear the weight of equipment and workpieces.
The high strength of 6mm aluminum plates ensures stable platform operation and prevents production disruptions due to platform deformation. Furthermore, the corrosion resistance of aluminum plates addresses potential corrosion from oil, chemicals, and other contaminants in factory workshops, reducing maintenance costs.
Outdoor Advertising and Signage: Large outdoor advertising signs and highway signs require extremely high strength and durability. 6mm aluminum plates can withstand the erosion of strong winds, heavy rain, and ultraviolet radiation, maintaining the flatness and clarity of lettering over a long period. The international outdoor advertising industry has high requirements for product lifespan; 6mm aluminum plates can meet their 5-10 year usage cycle needs, reducing the cost and hassle of frequent replacements.
Shipbuilding and Marine Engineering: 6mm aluminum plates are widely used in ship decks, bulkheads, and other components. The marine environment, characterized by high salt spray and high humidity, poses a significant challenge to the corrosion resistance of materials. 6mm aluminum plates, after special anti-corrosion treatment, can effectively resist seawater corrosion. Simultaneously, their high strength can withstand the turbulence and wave impacts during ship navigation, ensuring the safe operation of the vessel. Foreign shipbuilding companies, such as Norway's Kongsberg Group, have selected 6mm aluminum plates for some ship components.
