Al 3003 Brazed Aluminum Honeycomb Core For Building Exterior Walls

Al 3003 Brazed Aluminum Honeycomb Core For Building Exterior Walls

1. Descriptions:

The metallurgical bonding formed by brazing results in high node strength, and compared to adhesive honeycomb panels, its mechanical properties such as drum peeling strength, compressive strength, and tensile strength are superior. The porous structure of its honeycomb core results in a small solid cross-sectional area and an overall density much lower than the density of the material itself, effectively reducing the weight of the structure. Brazed aluminum honeycomb core is used for building exterior walls, roofs, indoor partitions, etc. It has good insulation and sound insulation effects, and can also improve the overall strength and stability of the building.

2. Specifications of brazed aluminum honeyomb core:

• Substrate type: The mainstream is aluminum alloy (such as 3003, 5052, 6061 series, commonly used in aviation grade 5A06, 2A12)
• Core aluminum foil thickness: usually 0.03-0.2mm (thinner for aviation grade, thicker for construction/transportation grade)
• Solder type: mostly aluminum based solder (such as Al Si system, melting point 577-615 ℃), which needs to be matched with the substrate to ensure metallurgical bonding.

• Side length: 3-15mm, For aviation, it is 3-6mm, and for construction, it is 8-15mm

• Thickess: 5-10mm, 10-30mm for high-speed rail carriages and 20-50mm for aviation structures

3. Brazed Aluminium Honeycomb core has several advantages:
Strong temperature resistance: The brazed honeycomb panel made of pure aluminum alloy has a forming process temperature of up to 600 ℃, and its temperature resistance depends on the aluminum alloy material, which is much higher than that of general adhesive honeycomb panels.
Good impact resistance: When subjected to external impact, the honeycomb core in the middle layer can decompose and absorb the impact energy, protect the panel, and reduce overall structural damage.
Good processability: It can accept secondary welding assembly of any thickness and area, which is convenient for processing, manufacturing, and assembly, and can meet the needs of different application scenarios.

4. Applications:

Petroleum floating plate: Welded honeycomb composite panel, which has the characteristics of "light weight", "high strength", and "lightning protection", has become an ideal material for floating roofs and external mesh shells in oil storage tanks. Effectively solved problems such as floating and sinking disks, structural disintegration, and oil and gas evaporation.

In the aerospace field, such as aircraft wings, fuselage structures, satellite components, etc., they can reduce the weight of aircraft, improve fuel efficiency and flight performance.

In the field of transportation, it can be applied to the floor, ceiling, and partition of high-speed rail and subway carriages, as well as the body structure of automobiles and ships, which can reduce the weight of vehicles and improve energy utilization efficiency.

In the field of architectural decoration, it is used for building exterior walls, roofs, indoor partitions, etc. It has good insulation and sound insulation effects, and can also improve the overall strength and stability of buildings.

5. Quality control:

A very technical engineering team. The general manager has worked in the Netherlands. The core technologies are introduced from the Netherlands. Others are very young and have more than 5 years of practical experience.

Strict QC team: 8 people are responsible for micro-porous aluminum honeycomb core of quality control of parts, processing, testing, packaging, etc.
