1, small density
The density of aluminium and aluminium alloys is close to 2.7g/, about 1/3 of iron or copper, and the strength of aluminium and aluminium alloys is high. After a certain degree of cold processing, the strength of the matrix can be strengthened. Some brands of aluminium alloy can also be strengthened by heat treatment.
2. Good conductivity and thermal conductivity
The thermal conductivity of aluminium is second only to that of silver, copper and gold.
3. Uniform coatings and various colors
Advanced electrostatic spraying technology makes the adhesion between paint and aluminium sheet uniform and uniform, with a variety of colors and a large choice space.
4, easy processing
After adding certain alloying elements, cast aluminium alloy with good casting properties or deformed aluminium alloy with good processing plasticity can be obtained. The aluminium plate has light weight, high tensile strength, good elongation and high recovery residual value. The process is good. Aluminum sheet can be processed into plane, arc, spherical and other complex geometric shapes by the process of first processing and then painting. Aluminum sheets are formed in factories, and can be directly processed twice without cutting.
5. Good corrosion resistance.
Aluminum surface is easy to naturally produce a dense and firm protective film of AL2O3, which can protect the matrix from corrosion. Cast aluminium alloys with good casting properties or deformed aluminium alloys with good processing plasticity can be obtained by artificial anodizing and coloring. PVDF fluorocarbon paint based on kynar-500 and hylur 500 can be used for 25 years without leg color.
