The Impact of Aluminium Profile Purity Differences on Light Reflectivity

June 06, 2024

The higher the purity of Aluminium Profile,the greater their reflectivity to light. Due to significant differences in the reflectivity of white light by aluminum profiles of varying purities, Aluminum Extrusion Profile that require a high surface brightness should opt for pure aluminum ingots or even high-purity premium aluminum ingots.

In addition, selecting the appropriate surface polishing such as mechanical polishing and chemical polishing, is essential to ensure that the aluminum profile maintains a high mirror-like reflective surface quality after anodization. For example, some Industrial Aluminum Profile can achieve an excellent shiny surface after chemical polishing with phosphoric-nitric acid solutions.

Those Industrial aluminum profiles can approach the brightness of high-purity aluminum after anodization. These highly reflective aluminum profiles are commonly used in automotive decorative components. Given that high-purity aluminum offers both superior and stable polishing results, these aluminum profiles are also employed in the production of goods with high added value.
