摘　　要：5B02-O铝合金Φ8 mm×0.75 mm管材用于飞机导管,用户对性能指标要求严格,在生产中该管材时常会出现抗拉强度超过用户所要求指标的情况。通过试验研究铸锭均火、毛料挤压、冷加工变形量、冷加工过程的中间退火及成品退火等工艺制度,找到合理的工艺方案,使产品的性能指标满足用户要求。The 5B02-O aluminum alloy tube with dimension of Ф8 mm x 0.75 mm is used as guide tube on aircraft. The mechanical properties of the tube are requested critically. The tensile strength is normally getting over the customer＇s requirement target. The reasonable processing system has been found through the investigation of ingot homogenization, stock extrusion, deforming ratio of cold working, annealing system during cold working process and annealing technology of final products. So the mechanical properties of the aluminum alloy tube can meet the requirements of customers.
