The sun affects metal primarily through its ultraviolet (UV) radiation and heat. UV radiation can lead to the degradation of protective coatings and finishes on metals, causing corrosion and rust over time. Additionally, the sun's heat can cause thermal expansion in metals, potentially leading to warping or structural changes. In outdoor environments, prolonged exposure to sunlight can significantly reduce the lifespan and integrity of metal objects.
