경량 알루미늄 소재 적용 Front End Carrier 개발

Development of Lightweight Front End Carrier of Aluminum Sheet

While all-aluminum front end carriers have been frequently used by major foreign auto-makers, the carriers domestically produced are typically hybrid types. It is understood that higher fuel efficiency due to weight reduction can be achieved by using aluminum carriers because of aluminum's light weight. Moreover, aluminum is expected to posess high corrosion resistance and recyling rate. As a first step to enhance feasibility of domestic production of all-aluminum carriers, several carriers made by advanced auto makers are examined and compared. Besides basic characteristics such as appearance and weight, physical properties including composition, strength and elongation are carefully analyzed to obtain critical design and process factors.
