Abstract
The invention discloses a zinc-base alloy. The zinc-base alloy is a Zn-Al-Cu-Mg series alloy and comprises the following elements in percentage by mass: 4%-5.5% of aluminum, 0.8%-1.2% of copper, 0.05%-0.08% of magnesium, not more than 0.02% of iron, not more than 0.001% of lead, not more than 0.002% of cadmium, not more than 0.001% of tin, and the balance of zinc and inevitable impurities, wherein the content of the zinc is no less than 94%, and the total content of the impurities is not more than 0.02%. By the manner, the zinc-base alloy is low in the content of detrimental impurities, has high corrosion resistance, high strength and high wear resistance and is suitable for the casting of metal ornaments and accessories which are high in accuracy and complicated in structure; and castings have high surface quality and are difficult to fracture.
Description
Technical field
The present invention relates to metal alloy compositions field, particularly relate to a kind of zinc base alloy.
Background technology
The main adding elements of zinc base alloy has aluminium, copper and magnesium etc., can be used for casting household electrical appliances accessory, building decoration, fittings of bathroom, lamp decoration part, toy, clothes metal insert etc., foundry goods need have higher surface quality and good surface treatment properties, and the common defect of Zinc Alloy Die Castings is surface blistering.
As everyone knows, in zinc base alloy, inevitably there is detrimental impurity, these detrimental impurity cause intergranular corrosion as lead, cadmium, tin can be gathered in crystal grain intersection, metallic matrix is because of intergranular corrosion fragmentation, and electroplate, accelerated this disaster, be subject to the position of intergranular corrosion can expand and by coating jack-up, cause cast(ing) surface to bubble.Particularly under wet environment, intergranular corrosion meeting makes casting deformation, cracking, even broken.For intergranular corrosion phenomenon, be mainly the detrimental impurity content of controlling in alloy raw material, particularly plumbous, lead also can damage human bone marrow's hemopoietic system and neural system alloy.Therefore the zinc base alloy a kind of with high corrosion resistance energy has become the trend of zinc alloy development.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of zinc base alloy, detrimental impurity content is low, has high corrosion resistance, has high strength, high-wearing feature simultaneously, is suitable for casting high precision, baroque metal decoration accessory, and surface quality of continuous castings is high, be difficult for breaking.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of zinc base alloy is provided, described zinc base alloy is that Zn-Al-Cu-Mg is associated gold, contained element and mass percent are: aluminium 4 %-5.5%, copper 0.8%-1.2%, magnesium 0.05%-0.08%, all the other are zinc and inevitable impurity, described zinc content is not less than 94%, described total impurities is not higher than 0.02%, and contained element and mass percent are: iron not higher than 0.02%, lead not higher than 0.001%, cadmium not higher than 0.002%, tin is higher than 0.001%.
In a preferred embodiment of the present invention, described impurity is not leaded.
In a preferred embodiment of the present invention, the total amount of described aluminium, copper, magnesium elements is 5.5%-6%.
The invention has the beneficial effects as follows: adopt aluminium, copper, the magnesium elements of reasonable ratio, improved the castability of alloy, increased intensity, hardness and the mobility of alloy, and reduced the response capacity to detrimental impurity; Especially effectively reduced the content of the impurity that cannot avoid in alloy, and in impurity, do not contained or containing the harmful metallic element lead of trace, reduced intergranular corrosion, made alloy there is high corrosion resistance.Zinc base alloy of the present invention is suitable for casting high precision, baroque metal decoration accessory, and surface quality of continuous castings is high, is difficult for breaking.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
The embodiment of the present invention comprises:
