Brass Has Those Ingredients

It is an alloy of copper and zinc. When zinc content is less than 39%, zinc can dissolve in copper to form single phase A, called single phase brass, good plasticity, suitable for hot and cold compression processing. When the zinc content is greater than 39%, there is a single phase and copper zinc based B solid solution, called dual-phase brass, B so that the plasticity is small and the tensile strength rises, only suitable for thermal pressure processing if the mass fraction of zinc continues to increase, the tensile strength decreases, no use value code with "H + number", H represents brass, The number represents the mass fraction of copper. For example, H68 represents the copper content of 68%, zinc content of 32%, brass, casting brass is in the code before the word "Z", such as ZH62 such as Zcuzn38 represents the zinc content of 38%, margin for copper casting brass. H90, H80 single phase, golden color, so there is a golden color, called plating, decorations, MEDALS, etc. H68, H59 are duplex brass, widely used in electrical structural parts, such as bolts, nuts, washers, springs and so on. In general, single-phase brass is used for cold deformation processing and dual-phase brass is used for hot deformation processing.
