Gun Metal

Gunmetal is a resilient bronze alloy historically renowned for its use in casting 19th-century firearms and heavy cannons.
It is traditionally forged from a highly durable mixture of approximately 88% copper, 10% tin, and 2% zinc.
Today, its exceptional resistance to steam and saltwater corrosion makes it a vital material for marine hardware, gears, and industrial valves.
Beyond the physical material, it has inspired "gunmetal gray," a sleek, dark shade characterized by subtle bluish or purplish undertones.
In modern design and fashion, this specific color is frequently utilized to convey a sophisticated aesthetic of industrial strength and authority.
