C6783
High Tensile Brass alloys are compositions of Copper and Zinc. Specifically, C6783 is classified as a duplex or alpha/beta alloy. C6783 brass alloy exhibits versatility by offering both high strength and excellent hot workability, making it a suitable choice for machining applications in engineering. It is occasionally identified as either a Manganese Bronze or High Tensile Brass due to its impressive characteristics.
