The aluminum alloy frame for electrical appliances is to fix the main body of the electrical appliances and protect the electrical appliances. The aluminum alloy frame is generally rectangular, and the size and thickness of the frame are customized according to the size and weight of the appliance. Reaching the refrigerator door, as small as the mobile phone frame, now use aluminum alloy profiles. Even the TVs, which claim to be borderless, also use aluminum alloy frames. So, what are the advantages of electrical aluminum alloy so that it can be widely used?
Advantages of Aluminum alloy frame for electrical appliances
1. Low density
The density of aluminum and aluminum alloy is close to 2.7g/, which is about 1/3 of iron or copper, and the strength of aluminum and aluminum alloy is high. After a certain degree of cold working, the strength of the matrix can be strengthened, and some aluminum alloys can also be strengthened by heat treatment.
2. Good electrical and thermal conductivity
The aluminum alloy frame for electrical appliances electrical and thermal conductivity is second only to silver, copper, and gold.
3. Uniform coating and diverse colors
The advanced electrostatic spraying technology makes the adhesion between the paint and the aluminum plate uniform, the colors are diverse, and the selection space is large.
4. Easy to process
After adding certain alloying elements, cast aluminum alloy with good casting performance or deformed aluminum alloy with good processing plasticity can be obtained. The aluminum plate has lightweight, high tensile strength, good elongation performance, and high recovery residual value. Good craftsmanship, using the process first and then painting process, the aluminum plate can be processed into various complex geometric shapes such as plane, arc, and sphere. The aluminum plate is formed in the factory, and it can be processed directly without secondary cutting.
5. Good corrosion resistance
The surface of aluminum is easy to naturally produce a dense and firm AL2O3 protective film, which can well protect the substrate 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 using Kynar-500 and hylur500 as the base material can reach 25 years.
