The hydrogen being mingled in journey：
(5) hydrogen detects：Dedicated instrument is selected to show the content of hydrogen in melt using liquid-phase extraction technology；
(6) it pours into a mould：It is poured into a mould using antigravity method or liquid level mold pouring technique, reduces the generation of oxide；
(7) cooling：Melt after cast is quickly cooled down in liquid nitrogen, obtains supersaturated solid solution；
(8) it processes：Cutting processing is carried out according to requirement to the aluminium alloy of machine-shaping using cutter.
The aluminium of the present invention, zinc, magnesium, scandium system wrought aluminium alloy manufacturing method, cutter in the step (8) can be with
Select the hard alloy cutter or diamond cutter of not the ultra-fine grain hard alloy cutter of coating or the band not method containing aluminium coat.
Beneficial effects of the present invention are compared with prior art：The present invention adds magnesium metal in aluminium, can improve aluminium conjunction
The corrosion resistance of gold, but it is easy the strength reduction enabled aluminum alloy to, therefore zinc and magnesium is added in the present invention simultaneously in aluminium, forms hardening constituent
Mg/Zn2 generates apparent invigoration effect to alloy, when Mg/Zn2 contents are improved from 0.5% to 12%, can be remarkably reinforced anti-
Tensile strength and yield strength improve the obdurability of alloy and at the same time scandium is added into aluminium, so that the performance that alloy has is improved, together
When be added tin and silver metallic addition, the cutting ability for the aluminium alloy produced can be improved, so as to improve aluminium alloy
Intensity, and its corrosion resistance can be improved, make the aluminium alloy produced that there is good quality.
