360 Brass hexagon bar, or key stock, is an excellent candidate for most processing techniques as well as both indoor and outdoor applications. When brass is exposed to natural elements, it will patina and develop a greenish or bluish hue over time. This product has great corrosion resistance, conducts electricity, and has a semi-smooth surface with a yellow-brass color and defined edges. Brass Hex bars are commonly used in corrosive environments, mechanical or architectural applications, gears or lock components, and ornamental projects. ASTM B16 360 brass is a standard specification for free-cutting brass rod, bar, and other shapes.
