IS 320 HT2

High Tensile Brass alloys are compositions of Copper and Zinc. HT2 falls into the category of duplex or alpha/beta alloys. This specific brass alloy, HT2, is highly versatile, offering high strength, excellent hot workability, and machinability. It is occasionally recognized as either Manganese Bronze or High Tensile Brass within the domain of engineering materials.
