What are the differences in thermal shock resistance between metals for fire-adjacent outdoor sculptures?

When selecting metals for fire-adjacent outdoor sculptures, thermal shock resistance is a critical factor. Metals like stainless steel, bronze, and aluminum exhibit varying levels of resistance to rapid temperature changes. Stainless steel, particularly grades like 316, offers excellent thermal shock resistance due to its low thermal expansion and high strength. Bronze, while durable, may develop stress cracks under repeated thermal cycling. Aluminum, lightweight and corrosion-resistant, has moderate thermal shock resistance but can warp under extreme heat. Understanding these differences ensures sculptures remain structurally sound and visually appealing in fire-prone environments. Proper material selection balances aesthetics, durability, and safety for long-term outdoor installations.
