Abstract

The invention discloses a processing process of a high-performance photovoltaic aluminum alloy frame, and belongs to the technical field of preparation of aluminum alloy materials. The processing process comprises the following steps of proportioning the following elements in percentage by mass: 0.60-0.65% of Si, less than or equal to 0.15% of Fe, less than or equal to 0.05% of Cu, less than or equal to 0.05% of Mn, 0.50-0.55% of Mg, less than or equal to 0.05% of Cr, less than or equal to 0.1% of Zn, less than or equal to 0.1% of Ti and the balance of Al, then carrying out casting, extrusion, sand blasting and oxidation procedures, and achieving processing and forming of the aluminum alloy frame. The Vickers hardness is 15 Hw or above, the mechanical property is high, compared with 6063 aluminum alloy, under the same strength requirement, the wall thickness of the photovoltaic solar frame can be reduced by 50% or above, the cost of aluminum for the photovoltaic frame is reduced by 50%, and the power generation cost of the photovoltaic industry is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of preparation of aluminum alloy materials, in particular to a high-performance photovoltaic aluminum alloy frame and a production process thereof. Background technique [0002] The global energy crisis promotes the rapid development of the new energy industry, and solar energy is the most important cost-saving energy among various renewable energy sources. Therefore, as a solar power generation technology that converts solar radiation energy into electrical energy, the photovoltaic industry is developing rapidly. Photovoltaic solar bracket is a special bracket designed for placing, installing, and fixing solar panels in solar photovoltaic power generation systems. It is characterized by no welding, no drilling, 100% adjustable, and 100% reusable. [0003] Today’s photovoltaic solar frame is mainly made of 6063 material, which has good surface quality but relatively low strength, and generally has a large wa...
