摩托车低成本铝合金方向把的开发

Development of Motorcycle Handlebar in Tapered Shape with Low Cost

探讨如何采用高强度铝合金材质生产摩托车方向把,使之实现轻量化及高强度的优良性能。Cu作为传统合金强化元素,其含量增加会带来降低生产率,提升成本的问题。因此,我们放弃了添加Cu,选择添加Zn来替代进行强化处理。通过优化工艺条件,改善了材料的抗应力腐蚀开裂性能,实现了同规格产品质量减轻20%,成本降低30%。

Application of tapered handlebars using high strength aluminum alloys is effective to weight reduction and high texture appearance. However, due to the influence of Cu contained as a strengthening element, the extrusion productivity of material pipe was low, and the cost was high. Therefore, an alloy in which the addition amount of Cu was suppressed and which was strengthened by addition of Zn was selected. In addition, stress corrosion cracking resistance was secured by optimizing manufacturing conditions.As a result, the weight was reduced by 20% and the cost was reduced by 30%.
