Document Type and Number:
WIPO Patent Application WO/2022/156075
Kind Code:
A1
Abstract:
An automobile hub aluminum alloy capable of being subjected to spin casting and rotary forging and a preparation method therefor, and an automobile hub and a manufacturing method therefor. The aluminum alloy comprises the following components in percentage by mass: 3.0%-4.0% of Si, 2.0%-2.5% of Mg, 0.5%-1.0% of Mn, 0.10%-0.50% of Zr, 0.05%-0.1% of Cr, 0.5%-0.8% of Cu, 0.1%-0.3% of Zn, 0.10%-0.20% of Ti, 0.01%-0.05% of B, 0.05%-0.1% of Y, 0.1%-0.2% of Er, 0.02%-0.05% of Sr, and the balance of Al. The preparation method mainly comprises melting alloying, refining, casting, heat treatment, deformation processing, and other steps. The aluminum alloy is simple in alloying, can be applied to a spin casting process and a rotary forging process to prepare a high-performance aluminum alloy hub.
