6061 aluminum alloy, as a 6-series aluminum magnesium silicon alloy, has moderate strength, good weldability, high corrosion resistance, can be heat treated to improve strength, and good mechanical properties, making it the mainstream material for solar photovoltaic brackets. Which type of bracket to choose is generally considered from the anti-corrosion performance, price, wind and snow resistance and other requirements of these two brackets. So how to choose between aluminum alloy photovoltaic bracket and steel bracket? This article will briefly introduce it to you. As the main skeleton of Aluminum Photovoltaic Bracket Accessories, the supporting structure is often made of high-strength aluminum alloy or hot-dip galvanized steel, which has excellent mechanical properties and environmental resistance; As the connecting link between various structures. Solar photovoltaic brackets are fixed devices in solar photovoltaic power generation systems, commonly made of materials such as aluminum alloy and stainless steel. Today Let's talk about the advantages of aluminum alloy photovoltaic brackets 1. Natural corrosion. Solar photovoltaics (PV) use the photovoltaic effect of semiconductor materials in solar cells to generate electricity from sunlight, which can be used for own use or sold to the public grid.
