7B04 | B95(Russia) | The fracture toughness of 7A04 alloy is higher than that of 7A04 alloy by 10%~15%. The main varieties are sheet, profile, extruded wall plate and bar, forgings and so on. There are three kinds of T6, T73 and T74 in use. The ingot of this alloy is more difficult than 7A04 alloy. It is suitable for hot forming, such as rolling, extrusion, forging and so on. It can make all kinds of parts of size and shape. | 440~590 |
