Solar Aluminum Profile

1. Introduction

Solar aluminum alloy profile is a material widely used in the field of solar photovoltaic. It has the advantages of light weight, high strength, corrosion resistance, good thermal conductivity, etc., and is widely used in the bracket system and component frame of solar photovoltaic power stations. This article will introduce solar aluminum alloy profiles in detail from multiple aspects such as material properties, production process application fields, etc.

2. Material properties

(1) Lightweight

Solar aluminum alloy profile is a lightweight material with a density of only about 2.7g/cm. Compared with steel, its weight is only about 1/3. This gives it a great advantage in suspension and support systems.

(2) High strength

Solar aluminum alloy profiles are made of high-strength aluminum alloy materials, so they have high tensile strength and yield strength. This makes it perform well when subjected to wind pressure and snow loads,

(3) Corrosion resistance

After oxidation treatment, the surface of solar aluminum alloy profiles can form a dense oxide film. This oxide film can effectively prevent the aluminum alloy material from chemically reacting with the surrounding environment, thereby improving its corrosion resistance.

(4) Good thermal conductivity

Solar aluminum alloy profiles have good thermal conductivity, which makes them more widely used in solar photovoltaic modules. Due to its good thermal conductivity, it can effectively convert sunlight into electrical energy.

3. 3. Production process

(1) Extrusion process

The main production process of solar aluminum alloy profiles is extrusion process. Extrusion is a process in which aluminum alloy bars are heated to a certain temperature and then extruded in an extruder. By adjusting the mold and extruder parameters, aluminum alloy profiles of various shapes and sizes can be manufactured.

(2) Surface treatment

Solar aluminum alloy profiles also need to be surface treated during the production process. Common surface treatment methods include oxidation, spraying and electrophoresis. Among them, oxidation is the most common surface treatment method, which can form a dense oxide film and improve the corrosion resistance of aluminum alloy materials.
