Abstract
The invention provides magnesium alloy with a high thermal conductivity for die-casting. The magnesium alloy includes the components as following: (1) 1.5 to 3 mass% of lanthanide, (2) 0.5 to 1.5 mass% of one or two of aluminium and zincic, and (3) 0.2 to 0.6 mass% of one or two elements from manganese and zirconium, and the residuals composed by the magnesium and inevitable impurities.
Description
Technical field
The present invention relates to the good die casting of a kind of thermal conductivity and use the high thermal conductivity magnesiumalloy, in more detail, the present invention relates to a kind of die casting scatterer etc. that is suitable for needs the die casting of the product of high thermal conductivity to use the high thermal conductivity magnesiumalloy.
Background technology
The die casting article of magnesiumalloy are widely used in various uses.But according to the difference of purposes, the intensity of magnesiumalloy and thermotolerance, thermal conductivity etc. are not enough to some extent.The thermal conductivity of pure magnesium is 167W/mK, but relatively, the thermal conductivity of for example common magnesium for die casting use AZ91 is lower than 90W/mK.The reason that thermal conductivity descends as stated is that solid solution has aluminium etc. to make the element of thermal conductivity variation in the magnesium sosoloid.If the die casting article of magnesiumalloy are used for parts that use in the pyritous environment for use or the parts that in use generate heat, then can't dispel the heat well, thermal distortion may take place in parts, is not suitable for the die casting article of magnesiumalloy are applied to scatterer etc.
So, proposed to be suitable for to make the duraluminum (for example with reference to patent documentation 1～6) of the various compositions of scatterer.But the quality of magnesiumalloy is lighter than duraluminum, considers from light-weighted angle, hopes to use the high thermal conductivity magnesiumalloy to make scatterer etc.
Magnesiumalloy is used in casting as high thermal conductivity, has proposed to contain magnesiumalloy (for example patent documentation 11) that magnesiumalloy (for example with reference to patent documentation 7), the magnesiumalloy (for example with reference to patent documentation 8～10) that contains high copper of thermal conductivity and calcium, the ratio of components with 0.5～1.5 (Ca/Al) of the zinc of 8～12 quality % contain aluminium and calcium etc.

Summary of the invention
The problem that invention will solve
The purpose of this invention is to provide the good die casting of a kind of thermal conductivity and use the high thermal conductivity magnesiumalloy.
Solve the means that problem is used
The inventor is for making magnesiumalloy contain a spot of aluminium and/or zinc for the castibility of keeping magnesiumalloy; But make the magnesium sosoloid that contains aluminium and/or zinc prevent the decline of thermal conductivity as far as possible near the state of pure magnesium, the technical scheme that is used for keeping alloy strength through the precipitation strength that is produced by precipitate has carried out conscientiously studying.The result finds, contains a spot of lanthanon through making magnesiumalloy, can obtain the good die casting of thermal conductivity and use the high thermal conductivity magnesiumalloy, thereby accomplish the present invention.
That is, die casting of the present invention is characterised in that with the high thermal conductivity magnesiumalloy, contains:
The lanthanon of (1) 1.5～3 quality %,
One or both elements that are selected from aluminum and zinc of (2) 0.5～1.5 quality % and
One or both elements that are selected from manganese and zirconium of (3) 0.2～0.6 quality %,
Form by magnesium and unavoidable impurities for surplus.
Preferably, die casting of the present invention is characterised in that with the high thermal conductivity magnesiumalloy, contains the lanthanum of 1.5～3 quality %, the aluminium of 0.5～1.5 quality % and the manganese of 0.2～0.6 quality %, is made up of magnesium and unavoidable impurities for surplus.
Preferably, die casting of the present invention is characterised in that with the high thermal conductivity magnesiumalloy, contains the lanthanum of 1.5～3 quality %, the zinc of 0.5～1.5 quality % and the zirconium of 0.4～0.6 quality %, is made up of magnesium and unavoidable impurities for surplus.
The effect of invention
Therefore die casting of the present invention can be carried out die casting with the high thermal conductivity magnesiumalloy, and thermal conductivity is good, is suitable for the product that die casting scatterer etc. needs high thermal conductivity.
Embodiment
Die casting of the present invention contains with the high thermal conductivity magnesiumalloy:
The lanthanon of (1) 1.5～3 quality %,
One or both elements that are selected from aluminum and zinc of (2) 0.5～1.5 quality % and
One or both elements that are selected from manganese and zirconium of (3) 0.2～0.6 quality %,
Form by magnesium and unavoidable impurities for surplus.
Die casting of the present invention with in the high thermal conductivity magnesiumalloy because one or both elements of containing lanthanon (for example lanthanum, cerium) and being selected from aluminum and zinc; So they form intermetallics; This intermetallics disperse to be present in close with pure magnesium mutually around; Consequently, the thermal conductivity of magnesiumalloy improves.When the content of lanthanon is lower than 1.5 quality %, the insufficient tendency of thermal conductivity is arranged, even and the content of lanthanon is higher than 3 quality %, the effect that also can't obtain to be complementary with it.
Die casting of the present invention is with containing one or both elements that are selected from aluminum and zinc that add up to 0.5～1.5 quality % in the high thermal conductivity magnesiumalloy.Through containing one or both elements that are selected from aluminum and zinc that add up to more than the 0.5 quality %, the melt temperature of magnesiumalloy reduces, and it is easy that die casting becomes.But, if contain one or both elements that are selected from aluminum and zinc that total over 1.5 quality %, even then form intermetallics as stated, the tendency that also has thermal conductivity to descend.
Die casting of the present invention with contain in the high thermal conductivity magnesiumalloy add up to 0.2～0.6 quality % one or both elements that are selected from manganese and zirconium as crystal grain miniaturization material.Through containing one or both elements that are selected from manganese and zirconium that add up to more than the 0.2 quality %; Can obtain the effect of crystal grain miniaturization; Even and the total content that is selected from one or both elements of manganese and zirconium is higher than 0.6 quality %, the effect that also can't obtain to be complementary with it.
Die casting of the present invention preferably contains the lanthanum of 1.5～3 quality %, the aluminium of 0.5～1.5 quality % and the manganese of 0.2～0.6 quality % with in the high thermal conductivity magnesiumalloy, is made up of magnesium and unavoidable impurities for surplus.At this moment, manganese also plays the effect of Impurity removal agent.
Die casting of the present invention preferably contains the lanthanum of 1.5～3 quality %, the zinc of 0.5～1.5 quality % and the zirconium of 0.4～0.6 quality % with in the high thermal conductivity magnesiumalloy, is made up of magnesium and unavoidable impurities for surplus.
Therefore the die casting of the invention described above can be carried out die casting with the high thermal conductivity magnesiumalloy, and thermal conductivity is good, is suitable for the product that die casting scatterer etc. needs high thermal conductivity.
The embodiment that gives an example below to specify of the present invention.
