The Shanghai Tian Rui Supplying copper | high-quality brass | quality aluminum and copper plate material: H59 brass; cheapest price, high strength, hardness and plasticity, but still well under heat treatment under pressure processing, corrosion resistance, similar to other performance and H62. For general machine parts, welding parts, hot red and hot rolling parts. 2, H62 brass; good mechanical properties, good thermal state plastic, cold plastic, cutting, easy brazing and welding, corrosion resistance, but prone to corrosion cracking. In addition, the price is cheap, is the application of recidivist a variety of ordinary brass. For a variety of deep drawing and bending manufacturing Shouli parts, such as pins, rivets, washers, nuts, catheters, barometer spring, screen, radiator parts. 3, H63 GB brass; apply to the cold state pressure processing, suitable for welding and brazing. Easily polished, brushed, rolled, bending, forming the main alloying. For screws, pickling with a round roller. Code H + digital means, H denotes the brass, the number indicates the mass fraction of copper. H68 copper content of 68%, 32% zinc, brass, cast brass "Z" in front of the code word, such the ZH62 such as Zcuzn38 zinc content of 38%, the balance being copper cast brass. H90, H80 single-phase, golden yellow, it is gold, Moreover, he called coating, decorations, medals. H68, H59 is a two-phase brass, widely used in electrical structural parts, such as bolts, nuts, washers, springs, etc.. Under normal circumstances, the cold deformation processing using a single-phase brass hot deformation processing phase brass. Shanghai Tian Rui Metal Materials Co., Ltd.
