| titleOfInvention | A kind of brass tube and preparation method thereof |
| abstract | The present invention relates to a kind of brass tube and preparation method thereof, it is characterised in that including following quality composition：Copper 61% 70%, phosphorus 0.5% 1%, arsenic 1% 2%, silicon 0.5% 1%, carbon 1% 2%, manganese 2% 3%, tin 0.5~1%, aluminium 0.01~0.1%, boron nitride 0.05 0.1%, magnesium nitride 0.01 0.05%, remaining is zinc and inevitable impurity, and 1) preparation method of inevitable total impurities≤0.03% is prepares brass tube embryo using continuous casting and rolling；2) phosphatization and saponification are carried out to brass tube embryo；3) the brass tube embryo after saponification is heated to after 700 800 DEG C carry out drawing process, the brass tube of size needed for obtaining；4) brass tube is subjected to normalizing and tempering processing；Brass tube prepared by the present invention is on the premise of corrosion resistance and high-elongation is ensured, also with hardness is big, wearability is good, good toughness and heat-resist, not easy to crack, service life length advantage. |
