Abstract
The invention relates to free-cutting extrusion zinc alloy. The free-cutting extrusion zinc alloy comprises the following chemical compositions in percentage by weight: 6-30 percent of aluminum, 2-7 percent of copper, 0.05-1.0 percent of bismuth, 0.01 percent of lead and 1t, 0.05-0.5 percent of other elements and the rest of zinc and inevitable impurities, wherein the other elements comprise at least two of rare earth, titanium and boron.
Description
Technical field
The present invention relates to a kind of Cutting free extruded zinc alloy.
Background technology
Plumbous as a kind of to human body and the great element of environmental hazard, such as plumbous to blood of human body and neural system, particularly can cause irreversible damage to the kidney of children and cranial nerve.In recent years, the understanding of countries in the world to the harm that lead brings to human body and environment is more and more deep, and has reached and know together widely, and government, the Risk health behavior of various harpoon to lead also form various ordering within a certain time.Such as: European Union ROHS instruction (forbidding of electric/electronic device objectionable impurities makes) in January, 2003 formally promulgates, on July 1st, 2006 formally implements, China has also promulgated " electronics and IT products pollution control management way " and enforcement in 1 day March in 2007 subsequently, recently water tap national environmental standard " environmental labelling product technical requirements water nozzle " has newly been promulgated again, and formal implementation from 1 day April in 2008.This series of loops is recommended with personal guarantee and is arranged, and has all given strict restriction to the content of heavy metal element lead in metal or amount of precipitation.In view of above reason, unleaded zinc alloy material is used in exploitation processing, has both met environmental protection development trend, has had again good market outlook.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of Cutting free extruded zinc alloy of environmental protection.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of Cutting free extruded zinc alloy, the weight percent of its chemical composition is: aluminium 6-30%, copper 2-7%, bismuth 0.05-1.0%, plumbous <0.01%, other element 0.05-0.5%, all the other are zinc and inevitable impurity; Other described element comprises: in rare earth, titanium, boron at least two kinds.
Further, the weight percent of its chemical composition is: aluminium 6-13%, copper 2-5%, bismuth 0.07-0.5%, plumbous <0.01%, other element 0.05-0.5%, and all the other are zinc and inevitable impurity; Other described element comprises: in rare earth, titanium, boron at least two kinds.
Compared with prior art, the invention has the beneficial effects as follows:
Cutting ability of the present invention is excellent has good mechanical property simultaneously, and easily realizes.
Embodiment
Below in conjunction with embodiment, the present invention is further illustrated.
The invention provides a kind of Cutting free extruded zinc alloy, the weight percent of its chemical composition is: aluminium 6-30%, copper 2-7%, bismuth 0.05-1.0%, plumbous <0.01%, other element 0.05-0.5%, and all the other are zinc and inevitable impurity; Other described element comprises: in rare earth, titanium, boron at least two kinds.
Further, the weight percent of its chemical composition is: aluminium 6-13%, copper 2-5%, bismuth 0.07-0.5%, plumbous <0.01%, other element 0.05-0.5%, and all the other are zinc and inevitable impurity; Other described element comprises: in rare earth, titanium, boron at least two kinds.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All any amendments done within the spirit and principles in the present invention, equivalent to replace and improvement etc., within the protection domain that all should be included in the claims in the present invention.
