Abstract

The invention relates to a light alloy photovoltaic bracket and a production technology thereof. A light alloy comprises the following elements of, by weight percentage, 0.5-9.2% of Al, 0.2-2.2% of Zn, 0.15-1% of Mn, 0-1% of Zr, 0-0.5% of Nd, 0-0.8% of Sr, impurity elements being Si, Fe , Ni, Cu with the content of a single element being less than 0.01% and the total content being less than 0.05%,and the balance Mg. Through the production technologies of pure magnesium microalloying refining casting, homogenizing annealing, extrusion molding, solid solution aging, mechanical machining, surface treatment and the like, the prepared light alloy bracket is lighter than a steel bracket and an aluminum alloy bracket, the molding is more efficient, the packaging and transportation are more convenient, the transportation and mounting are faster, and the comprehensive cost of a photovoltaic power generation system is reduced.

Description

technical field [0001] The invention relates to the technical field of light alloy deep processing, in particular to a light alloy photovoltaic support and a production process thereof. Background technique [0002] Solar photovoltaic support is a special support designed to place, install and fix solar panels, and is an important support and fixture in photovoltaic modules. According to the different materials used for the main stress-bearing members of the photovoltaic support, there are mainly steel supports, aluminum alloy supports and non-metal supports, among which non-metal supports are used less. [0003] At present, the steel and aluminum alloy materials used in photovoltaic brackets are heavy and require high load-bearing capacity of the component base, and the handling and installation are labor-intensive, time-consuming, and costly. Therefore, reducing the weight of photovoltaic supports, improving the efficiency of handling and construction, and saving installa...
