The surface of aluminum is easy to produce a dense and firm Al2O3 protective film naturally, which can well protect the matrix from corrosion. Through artificial anodizing and coloring, cast aluminum alloy with good casting performance or deformed aluminum alloy with good processing plasticity can be obtained. PVDF fluorocarbon paint with kynar-500 and hylur 500 as base materials can reach 25 years without leg color.
After adding certain alloy elements, cast aluminum alloy with good casting performance or deformed aluminum alloy with good processing plasticity can be obtained. The aluminum plate has light weight, high tensile strength, good elongation and high recovery residual value. Good manufacturability. The aluminum plate can be processed into various complex geometric shapes such as plane, arc and spherical surface. The aluminum plate is formed in the factory and can be directly processed twice without cutting.
