Comparison of composite aluminum plate 2024 6061 and aluminum alloy veneer



Composite aluminum plate – two 0.5mm thick aluminum plate in the middle folder PVC or PEC plastic roll, heat together.
Aluminum alloy veneer – 2 ~ 3mm aluminum alloy plate.

Fluorocarbon coating
Composite aluminum plate – one-time roll made, the coating thickness is generally 20μm.
Aluminum alloy veneer – 2 times or 3 times to complete the coating, the coating thickness is generally 30 ~ 40μm.

Aluminum composite panel – can choose a variety of colors, color main points: monochrome and magic color system, patented color products with a film surface, excellent durability, color and good identity.
Aluminum alloy veneer – according to the design and the requirements of the owners of any color selection.

Composite aluminum plate – made about 10 years of domestic plate, imported sheet fineness and strength of up to 20 years and more years, maintenance-free.
Aluminum alloy veneer – up to 15 years, mostly due to wind pressure caused by deformation, the board color spent.

Composite aluminum plate – four corners open.
Aluminum alloy veneer – four corners welded together.

Wind resistance
Composite aluminum – wind pressure deformation is small, the import of composite sheet of high wind pressure strength.
Aluminum alloy veneer – wind pressure deformation of large, easy to deformation.

Anti-temperature degeneration
Composite aluminum plate – ordinary adhesive processing of composite panels, aluminum and plastic expansion coefficient is quite different, prone to blistering, stripping phenomenon. However, the choice of DuPont folder membrane membrane, it will not blister, stripping.
Aluminum alloy veneer – the same material, the temperature changes when the wall itself has no effect.

Lightning resistance
Composite aluminum – not anti-lightning, a strong current is difficult to ground through the composite aluminum, 0.5mm thick aluminum will be breakdown.
Aluminum alloy veneer – can be used as a good conductor of electricity, through the building grounding system to lightning rapid transmission of the current to the ground.

Composite aluminum – can be processed on-site to meet the size of the building building errors caused by errors.
Aluminum alloy veneer – production plant production, to adapt to the site building error is poor, the secondary design requirements.

Finished rate
Composite aluminum – generally 80% ~ 95%.
Aluminum alloy veneer – 100%.

Composite aluminum plate – on-site manual operation planing groove, if the depth of the groove control is not good, will hurt the outer aluminum, so that bending fracture, resulting in waste, the yield is generally 96% to 98%.
Aluminum alloy veneer – the production plant production, factory finished rate of 100%.

Construction Quality
Composite aluminum – due to the wall for more on-site processing, poor quality control conditions, jerry-building, shoddy situation prone to appear in this link, the quality of the wall will affect the construction quality.
Aluminum alloy veneer – the production plant in accordance with international standards to control the quality of production, wall quality and reliable, to provide the premise of ensuring the quality of construction.

The scope of application
Composite aluminum plate – suitable for curtain wall works.
Aluminum alloy veneer – for facade decoration, elevated corridor, pedestrian bridge, low-rise curtain wall.

Environmental protection
Composite aluminum – the choice of core materials, the general core of high temperature will produce harmful gases, no fire, not easy to recover.
Aluminum alloy veneer – fire, easy to recover, do not pollute the environment.
