can't quite agree with you....

1．重量轻
yes
2．强度大
No. steel wheel is more robust, that is why police chose steel,not only for financial reason.
3．散热性好
yes
4．精度高
yes,
5．美观
yes
6．耐腐蚀性强,比起钢轮圈，铝合金轮圈不会生锈。
No.absolutely wrong.
In big snow winter,exp. in Canada, they put salt to dissolve snow.The salt is very 腐蚀性强, that is why for some drivers, they change their alloy rim to steel,because steel rim is more 耐腐蚀.
