More Information
Summary:The invention discloses a large-size aluminum alloy ultrathin-wall-thickness hollow round cast ingot which is composed of the following elements of, by weight, 1.0%-1.45% of Si, 0.1%-0.3% of Fe, 0.8%-1.2% of Cu, 0.8%-1.2% of Mn, 0.8%-1.2% of Mg, 0.15%-0.25% of Cr, smaller than 0.03% of Ti and the balance Al, the outer diameter of the manufactured hollow round cast ingot finished product is phi 560 +/-3 mm, the inner diameter of the manufactured hollow round cast ingot finished product is phi 360 +/-3 mm, and the wall thickness of the manufactured hollow round cast ingot finished product is 100 +/-1 mm. During preparation, through the procedures of smelting, purifying, degassing, filtering, casting and the like, the hollow round cast ingot finished product for the large-tonnage extruding machine is obtained through one-time forming machining through specific alloy component composition and the smelting and casting technology, the current technical blank is solved, all indexes of the prepared hollow round cast
