A kind of brass alloys, include by weight percentage：65%~70% copper, 5.5%~6.5% aluminium, 2%~
2.5% iron, 2%~2.5% nickel, 2.8%~3.5% manganese, 0.25%~0.5% lead, 0.6%~1% silicon and
13.5%~19.8% zinc.
Further, the brass alloys include by weight percentage：67% copper, 5.5% aluminium, 2% iron, 2.5%
Nickel, 3.5% manganese, 0.25% lead, 1% silicon and 18.25% zinc.
Further, the impurity content of the brass alloys is less than or equal to the 0.5% of brass alloys gross weight.
A kind of manufacture method of brass alloys, comprises the following steps：
(1) dispensing：Raw material are weighed by weight percentage；
(2) melting：The 50% of copper raw material are first put into, the first coverture is laid on copper raw material, carries out melting；Throw again
Enter manganese raw material, the second coverture is laid on manganese raw material；Nickel raw material and iron raw material are put into again, carry out melting；Throw again
Enter remaining 50% copper raw material, carry out melting, stirring；Zinc raw material and silicon material are put into again, carry out melting；Put into again
Aluminium raw material and lead raw material, carry out melting and obtain brass alloys liquation；Brass alloys liquid is stirred, then heating input
Refining agent carries out deslagging refining；Stand insulation and slagging-off；
(3) continuous casting：Insulation carries out horizontal casting billet, and casting speed is 2.5m/h~4m/h, and billet is sawed into spindle；
(4) extrude：Spindle be heated to 630 DEG C~750 DEG C carry out hot extrusions obtaining extruding pipe or extrude rod.
Further, the step (2) is 5min~10min to the mixing time of brass alloys liquid.
Further, a diameter of 140mm of the billet of the step (2).
Further, the first coverture of the step (2) is charcoal, and the second coverture is borax.
Further, the extrusion speed of the step (4) is 15mm/s~35mm/s, and extrusion ratio is 15~35.
Relative to prior art, the present invention produces big intensity by increasing silicon, nickel and the content of manganese, to matrix and consolidated
Molten reinforcing, corrosion resistance can be increased substantially, by the interaction between alloying element, make on brass base forming component it is complicated,
The high wear-resisting phase of uniform and stable distribution, hardness, advantageously reduce the raw material usage amount of copper.
