C3602
C3602, a brass alloy created by blending copper and zinc for enhanced machinability, exhibits the highest level of ease in machining among all copper alloys, setting the standard against which others are compared. C3602 Brass is notable for its robustness and resistance to corrosion, showcasing properties closely akin to steel. It stands as one of the most widely utilized copper alloys in contemporary applications. The precision machining of C3602 Brass is a straightforward task. Despite its ductile state when softened, C3602 Brass remains formidable and sustains its strength even under the most strenuous conditions. C3602 Brass develops a delicate protective “patina,” distinguishing it from steel and iron by resisting rust when exposed to atmospheric conditions. With its elevated density, C3602 Brass is particularly suitable for crafting heavy industrial components. Additionally, the polished finish of C3602 Brass is highly valued. This versatile material is offered in various configurations, including rounds, flats, squares, hexagons, shapes, and hollows.
