7Y69。
Compared with prior art, the invention has the beneficial effects as follows：The anti-wear-resistant aluminum alloy of superhigh intensity has lightweight, intensity
High, anti-wear-resisting advantage, can be widely used for manufacturing speed changer synchronizing tooth ring and other auto parts and components.With very good Jing
Ji benefit and social benefit.Also being provided to Aeronautics and Astronautics, unmanned plane and underwater vehicle etc. simultaneously needs to use superelevation strong
Degree, and and need light-weighted field to apply.
Specific embodiment
The present invention is described in further detail with reference to specific embodiment：
The present invention uses wrought aluminium alloy chemical composition standard GB/T/T3190 and Cast aluminium alloy ingot country mark
In quasi- GB/T8733 without formula, the anti-wear-resistant aluminum alloy of superhigh intensity of the present invention is by aluminium, copper, magnesium, zinc, neodymium, zirconium, nickel, titanium
Element melting is made, and is carried out on aluminum alloy smelting furnace and casting unit.
1. first melting is carried out in aluminum alloy smelting furnace；
2. at a temperature of 710 DEG C -800 DEG C, aluminium ingot 76.5～the 85.7%, (copper of electrolytic copper plate 1.6～2.9% are initially charged
Can also be in the form of aluminum bronze intermediary alloy), add zirconium 0.05～0.20%, after carry out melting；
3. temperature is risen to into 750 DEG C -810 DEG C after aluminium, copper, zirconium all dissolve, add magnesium 1.8～2.9% and zinc 7.0
～13.5%, then carry out melting；
4. after aluminium, copper, zirconium, magnesium, zinc all melt and is interposed between together, titanium is added when temperature is risen to into 780 DEG C -830 DEG C
0.01～0.07% and neodymium 0.2～1.3%, after carry out melting；
5. treat that various composition is substantially dissolved in together, degasification deslagging refining is then carried out again；
6. by it is molten every aluminium alloy round casting rod or square ingot casting are cast on casting unit；
If being 7. cast into the aluminium that circle casting rod is just crushed to round casting rod manufacture speed changer synchronizing tooth ring using extruder
Alloy pipe stock or bar stock.Need the sheet material of thickness same for manufacturing speed changer if the side's of being cast into ingot casting is just rolled into using milling train
Step ring gear.
8. ingot casting is squeezed into after pipe, rod or sheet material carries out Quenching Treatment, and quenching is carried out in glowing furnace, and hardening heat is
455 DEG C -515 DEG C, the cool time is 3-5 hours, and the time uses cold water chilling to rear；
9. the material after Quenching Treatment is carried out again Ageing Treatment, timeliness is carried out in aging furnace, and aging temp is 120
DEG C -180 DEG C, aging time is 26-30 hours, and aging time is to rear material along with the furnace cooling.
The anti-wear-resistant aluminum alloy 7Y69 of superhigh intensity of the present invention may be cast processing, then extrude, forge and press, rolling and be processed into manufacture
The blank pipe fitting of synchro converter ring, forging-ring or sheet material, then forged and machining is manufactured into synchro converter ring.
7Y69 tensile strength Jing after T6 process is more than 730MPa, and yield strength is more than 610MPa.(according to existing seamless aluminium tubing
