Abstract: |
Smelting process and heat treatment of high-strength aluminum alloy ZL205A were investigated. According to the characteristics and quality of the support structure requirements, the practical casting process was developed and a bearing casting was poured. The results show that the performance and quality of the high-strength aluminum alloy ZL205A castings meet to the design requirements and it has basically the same reliability with forgings used in bearings, which can be a substitute to reduce the manufacturing cost of the structural parts and shorten the manufacturing cycle. |
