The accounting of 3wt%, Fe are 0.5-1wt%, and the accounting of Cu is 1.5-2.5wt%, and the accounting of Zn is 10-13wt%, and the accounting of Mn is
The accounting of 1-2wt%, Zr are 0.15-0.20wt%, and surplus is aluminium and inevitable impurity.
It preferably, also include the grain refiner containing Ti and B of optionally 0.01-0.2wt%.
Preferably, the ratio of the Fe/Mg is adjusted within the scope of 0.2-0.4, preferably in 0.25-0.35.
Preferably, the Zn is the Zn in intermediate alloy Al-Zn, and the Zr is the Zr in intermediate alloy Al-Zr.
Technical solution of the present invention second is that:
A kind of preparation method of high hardness aluminium alloy material, includes the following steps:
Step 1: alloy casting: regarding Al fusing as molten bath, furnace temperature is risen to 840-860 DEG C；
Step 2: Cu, Fe, Mn and intermediate alloy Al-Zr is added, is cooled to 790-810 DEG C after fusing, stirs and intermediate conjunction is added
Golden Al-Zn, Mg is added in stirring after fusing, stirs evenly；
Step 3: temperature is reduced to 600 DEG C, is transferred in heat extruder and carries out hot extrusion molding.
High hardness aluminium alloy of the invention can be used for the manufacture of ATM machine shield.
When for manufacturing ATM machine shield, cast by extruding, forging or in permanent mold to be produced.
By high hardness aluminium alloy material of the invention produced above, hardness is at least 200HV, more preferably at least
