Abstract: A continuously cast aluminum alloy rod 101 is produced through a horizontal continuous casting method employing a tubular mold which is supported such that its center axis extends substantially horizontally and which has a forced cooling device. The rod includes a Si-rich portion 104 having a thickness of at least 20 ?m on a surface of a lateral side of the rod that has a central angle 103 of at least 30°.
