Wherein the cabinet is made of aluminium alloy, and the ingredient of the aluminium alloy is by mass percentage are as follows: and Mg0.6%~
0.9%, Si0.4%~0.6%, Mn0.1%~0.3%, Cr0.3%~0.4%, Fe0.2%~0.3%, Ti0.3%~
0.4%, Zr0.2%~0.4%, Sc0.2%~0.3%, surplus Al, wherein the ratio of Mg and Si is 1.3~1.7:1.
The present invention uses the aluminium alloy of reasonable element proportion, and the performance of aluminium alloy can be improved.The impurity member in aluminium alloy
Element, alloying element state is precipitated and non-solid solution state is present in metal, resistance is smaller, and electronics is easier to be passed through, and metal is led
Electricity, heating conduction are better, and the addition of rare earth Zr has the function of degasification and removal of impurities, and stable rare earth hydrogenation can be generated with hydrogen
Object (ReH2, ReH3) changes existing forms of the hydrogen in molten aluminum, inhibits the forming core of bubble, and therefore, the aluminium alloy added with Zr is solidifying
Pin hole rate decline after Gu；Rare earth can also form stable intermetallic compound (such as with the former objectionable impurities being solid-solubilized in aluminium such as iron
FeRe5 it) is precipitated in crystal boundary, to reduce the solid solution capacity of impurity element in the base；And damage of the micro Zr to aluminium electric conductivity
Less than Cr, Mn, Ti, Al under the conditions of equilibrium freezing aluminium at room temperature hardly be dissolved Zr, can in nonequilibrium freezing Zr in aluminium
In solid solubility expand, even up to 4.9% under conditions of Quench.It is big using solid solution Zr atom diffusion activation energy, in aluminium lattice
In diffusion it is very slow, carry out anchoring dislocation, the heat resistance of Al alloy can be improved.But with the increase of rare earth adding quantity, aluminium
The conduction of alloy, heating conduction can occur reducing tendency again, are on the one hand the additions of rare earth, cause aluminium alloy grain structure
Refinement, increases the difficulty that electronics passes through, the increase of another aspect rare earth content causes part rare earth to be solid-solution in aluminium alloy crystal
Therefore needing suitable additive amount just can guarantee the maximization of performance.
Solid solubility of the Sc in aluminium is 0.27% at 655 DEG C, and with the reduction of temperature, the solubility of Sc is drastically reduced, institute
The Al3Sc phase of very high density can be precipitated.Al3Sc phase is a kind of LI2 type phase, with parent phase aluminium coherence, has great coherence wrong
Match, therefore there is strong pinning effect so that alloy is remained that fine grain is granular so that crystal grain be hindered to grow up dislocation and subgrain

Strong dispersion-strengthened action, and the recrystallization temperature of aluminium alloy can be significantly improved, therefore, Sc can significantly improve the strong of aluminium alloy
Degree, wearability.
Sc and Zr is added simultaneously in aluminium alloy of the present invention, can be formed the more complicated ternary compound Al3 of composition (Sc,
Zr), the beneficial effect of Sc is improved.If Al-Sc-Zr ternary alloy three-partalloy is in addition to generating the big Al3Sc particle of size, there are also sizes more
Small Al3Sc containing zirconium or Al3 (ScZr) phase, structure are also Ll2 type, and with matrix coherence, can effectively prevent the migration of dislocation
Formation with subgrain is grown up or is merged.Therefore, this size is small, the presence of density height and the AlScZr phase being evenly distributed, can be into
One step significantly refines crystal grain and improves recrystallization temperature, obtains the tissue of non-recrystallization, moreover it is possible to strong inhibition grain boundary fracture tendency,
Be conducive to improve intensity, the plasticity of alloy.
Further, the ratio of Mg and Si is 1.3~1.7:1 in the aluminium alloy, when magnesium silicon ratio is 1.5~1.7:1
When, superfluous micro Si is just with Fe Dispersed precipitate in aluminum substrate in aluminium alloy, to reduce Si, Fe element in aluminum substrate
In solid solubility.When element silicon is superfluous more, superfluous silicon is not only solid-solution in aluminum substrate, is also easily formed with iron coarse
Phase, therefore the capacity of heat transmission is caused to be declined.
