The aluminum brass alloy comprises zinc, copper, aluminum, arsenic, titanium, nickel, chromium, boron, etc., and the aluminum brass alloy comprises the components by the following weight percentage: 76.0 to 79.0 % of copper(Cu), 1.8 to 2.5 % of aluminum (Al), 0.02 to 0.06 % of arsenic (As), 0.01 to 0.10 % of titanium (Ti), 0.05 to 1.0 % of nickel(Ni), 0.01 to 0.50 % of chromium (Cr), 0.001 to 0.10 % of boron (B), zinc (Zn) as the rest and the total amount of at most 0.05 % of impurity. The proportion design of the present invention is reasonable, and on the basis of existing aluminum brass corrosion-resistant alloys, the arsenic (As), the titanium (Ti), the nickel (Ni), the chromium(Cr) and the boron (B) are added according to the main corrosion forms of the material in use so that a special surface film containing minor elements is formed on the surfaces of the material by microalloying so that the secondary surface corrosion is prevented, and the corrosion resistant property is enhanced.
Description
Technical field
The present invention relates to a kind of anticorodal aluminum brass alloys, belong to metallic material alloyization and material antiseptic erosion technical field.
Background technology
The main trade mark of existing aluminum brass non-corrosive metal is HA177-2, its each component is by weight percentage: Cu 76.0～79.0%, Al 1.8～2.5%, all the other are not more than 0.05% impurity for Zn and total amount, though this aluminum brass non-corrosive metal has Dezincification corrosion resistant and anti-erosion corrosion ability preferably, is containing NH
4 +, Cl
-, when abominable condition of water quality such as high salt uses down, its resistance to corrosion is relatively poor, easily is corroded, cause tubing to leak, thereby has influenced the work-ing life that application aluminum brass non-corrosive metal pipes such as steam turbine, condenser carry out the equipment of condensing heat-exchange.
Along with problems such as environmental pollution become increasingly conspicuous, the prolong environment for use is more abominable, and the corrosion resisting property of the non-corrosive metal that is used to make prolong is also had higher requirement.When existing HA177-2 alloy used in polluting bigger water quality, its life-span had only 3～5 years, and replace tubes is frequent, has not only reduced the efficient of unit, and has increased consumption, caused cost to rise.Therefore existing aluminum brass non-corrosive metal has been difficult to satisfy the service requirements of prolong alloy material.
Summary of the invention
The purpose of this invention is to provide a kind of anticorodal aluminum brass alloys with comparatively ideal corrosion resisting property and mechanical property.
The present invention is a kind of anticorodal aluminum brass alloys, includes zinc, copper, aluminium is characterized in that also comprising simultaneously arsenic, titanium, nickel, chromium, boron etc., the composition of its each component is respectively by weight percentage: copper (Cu) 76.0～79.0%, aluminium (Al) 1.8～2.5%, arsenic (As) 0.02～0.06%, titanium (Ti) 0.01～0.10%, nickel (Ni) 0.05～1.0%, chromium (Cr) 0.01～0.50%, boron (B) 0.001～0.10%, all the other are that zinc (Zn) and total amount are not more than 0.05% impurity.
The composition of described each component can be preferably respectively by weight percentage: copper (Cu) 76.0～79.0%, aluminium (Al) 1.8～2.5%, arsenic (As) 0.02～0.06%, titanium (Ti) 0.05～0.10%, nickel (Ni) 0.05～0.20%, chromium (Cr) 0.02～0.10%, boron (B) 0.05～0.10%, all the other are that zinc (Zn) and total amount are not more than 0.05% impurity.
Described arsenic (As) can copper-arsenic (Cu-As) master alloy mode add in zinc (Zn) ingot and aluminium (Al) ingot.Described titanium (Ti) can copper-titanium (Cu-Ti)) mode of master alloy adds in zinc (Zn) ingot and aluminium (Al) ingot.Described nickel (Ni) can copper-nickel (Cu-Ni) master alloy mode add in zinc (Zn) ingot and aluminium (Al) ingot.Described chromium (Cr) can copper-chromium (Cu-Cr) master alloy mode add in zinc (Zn) ingot and aluminium (Al) ingot.Described boron (B) can copper-boron (Cu-B) master alloy mode add in zinc (Zn) ingot and aluminium (Al) ingot.
The present invention is on the basis of existing aluminum brass non-corrosive metal, at the in use main form of corrosion of this material, add arsenic (As), titanium (Ti), nickel (Ni), chromium (Cr), boron (B) element of trace, form the special list facial mask that contains trace element at material surface by microalloying, stop the corrosion of two subsurfaces, thereby improved corrosion resisting property, its proportion design is reasonable, compare with existing aluminum brass non-corrosive metal, at dissolved solid 4500mg/l, NH
4 +100mg/l, Cl
-Following abominable water quality, the polluted water environment of 2200mg/l, quantity of sand and mud 600mg/l descends and the large-scale thermal power machine group is used in the condenser, has better corrosion resisting property.Anticorodal aluminum brass alloys of the present invention can be widely used in the fields such as manufacturing of condenser, steam turbine, interchanger usefulness tubing.Result of use in coastal water quality is better, and with the heat exchanger brazed copper tube that anticorodal aluminum brass alloys of the present invention are made, can reach more than 15 years work-ing life, and alternative White Copper Tubes is used for air removal section.
Embodiment
Frequency cored induction furnace is adopted in the preparation of anticorodal aluminum brass alloys of the present invention, in the copper zinc alloy melt, press composition proportioning and order of addition(of ingredients), add zinc (Zn) ingot, aluminium (Al) ingot and copper-arsenic (Cu-As), copper-titanium (Cu-Ti)), materials such as copper-nickel (Cu-Ni), copper-chromium (Cu-Cr), copper-boron (Cu-B) master alloy, adopt vertical direct chill casting, prepare cylindrical anticorodal aluminum brass alloys ingot.The add-on of its each component is respectively by weight percentage: copper (Cu) 76.0～79.0%, aluminium (Al) 1.8～2.5%, arsenic (As) 0.02～0.06%, titanium (Ti) 0.05～0.1%, nickel (Ni) 0.05～0.2%, chromium (Cr) 0.02～0.10%, boron (B) 0.05～0.10%, all the other are zinc (Zn).
