                    An important factor behind this
                    advance is that aluminium producers,
                    such as Tokyo-based UACJ Corporation,
                    have succeeded in developing advanced
                    aluminium alloys and introducing   Markus Bereszewski

                    Another very important aspect of the
                    trend is the technology used for joining
