摘要
为满足板翅式换热器用铝合金翅片箔承压能力的要求,设计开发了Al-1. 4Mn-0. 5Si-0. 8Fe合金。该合金是在3003铝合金的基础上加入了少量的Zr、Cr、V、Ti等微合金元素;试验研究了生产翅片箔用的该合金铸锭的均匀化退火工艺,该合金铸锭适宜的均匀化退火工艺为610℃7 h。
Al-1. 4 Mn-0. 5 Si-0. 8 Fe alloy was researched and developed with small amount of Zr,Cr,V,Ti and other micro-alloying elements added on the basis of 3003 aluminum alloy,to meet the requirements of reducing the thickness and improving the pressure bearing ability of aluminum alloy fin foil used on the plate-fin heat exchanger. The homogenization process was studied in the experiments for Al-1. 4 Mn-0. 5 Si-0. 8 Fe alloy ingot and the result shows its proper homogenization process is 610℃ 7 h.
