interrupted aging

The mechanical properties of 7A04 aluminium alloy rods can meet with the customers requirements and the super-high strength aluminium alloy rod's productivity effect can be improve by means of optimizing the chemical components,improving the homogenization annealing process,adopting double hole extrusion die and higher temperature solid solution and two step ageing et al.

通过优化7A04铝合金成分配比与均匀化处理工艺,采取双孔模具挤压、高温固溶处理与二段分级时效等方法,满足了用户对产品性能的要求,提高了生产效率,实现了批量化生产超高强铝合金挤压棒材的目标。
