EFFECT OF SURFACE COATING LUBRICITY ON ALUMINUM FIN-STOCK FORMABILITY

摘要

We studied the effect of surface coating lubricity on aluminum fin stock formability using evaporative lubricants, which are mainly in use recently. Surface treatment decreasing surface friction showed following results : (l)The limiting ironing ratio improves. (2)The wear of forming tools is decreased. (3)The troubles of fin-pitch disorder in the product are decreased.
