The invention discloses a novel light high-strength high-strength frame. The novel light high-strength high-strength frame is characterized in that the frame comprises a head tube, a middle tube, an upper tube, a lower tube, an upper fork, a lower fork, a bottom bracket and a rear hook claw; one end of the upper tube is welded to the head tube, the other end of the upper tube is welded to the middle tube, one end of the lower tube is welded to the head tube, the other end of the lower tube is welded on the bottom bracket, one end of the upper fork is welded on the middle tube, the other end of the upper fork is connected with the other end of the lower fork through the rear hook claw, one end of the lower fork is welded on the bottom bracket, and the bottom bracket is welded on the middle tube; the head tube, the middle tube, the upper tube, the lower tube, the upper fork, the lower fork, the bottom bracket and the rear hook claw are all made of 6J01 aluminum alloy tubes. the 6J01 aluminum alloy tubes are adopted to replace 6061 aluminum alloy tubes; and after the frame is welded, heat treatment and straightening procedures do not need to be carried out on the frame, so that the production efficiency of the frame is improved, and meanwhile, the production cost is reduced.
