摘 要
截至目前為止，鮮少研究團隊探討鋁合金產品與應用在建築構面，我國鋁合金材料和產品生產技術在諸多方面已處於世界前列，很多相關技術可以導入建築用鋁合金的應用，因此，開發設計鋁合金在建築或休憩硬體領域的應用，特別是耐磨耗性與海島國家的腐蝕特性的探討對建築產業的升級和推廣應用都有極其重要的意義。考量台灣許多建築材料仍以鋼筋與鑄鐵材料為主，不僅笨重又不耐鏽蝕，更有磨耗嚴重問題，基於此，本計畫擬開發鋁材: 4389, 5089, 6169新式鋁合金綠建材，並且將商用4032, 5052, 6061材料同步分析與比對。實驗結果顯示，新式4389, 5089, 6169材料特性、組織、拉伸機械性質、鹽霧試驗均較商用型4032, 5052, 6061材料性質優異，尤其是耐腐蝕特性，值得注意是，新式6169具備高強度的擠型材料，可供應用於海濱工業、遊憩園區或建築結構支撐建材應用參考。

Abstract
Limited research teams have examined aluminum alloy products and the applications in building facets in recent decades. Taiwan’s Aluminum alloy materials and product technology are maintaining the leading position in many aspects. Many related technologies can be implemented into the application of aluminum alloy for construction. The application of designing aluminum alloys in the construction field, especially the exploration of wear resistance and corrosion characteristics of island countries, is of great significance to the upgrading and promotion of the construction industry. However, the use of construction materials in Taiwan are still mainly concerned with steel and cast- iron materials, which are bulky and not rust-resistant, along with wear problems. Based on the discussion above, the plan is to develop and design new aluminum alloys for construction. Green building materials, 4389, 5089, 6169, were analyze and compared with commercial materials 4032, 5052, 6061. The results show that new type 4389, 5089, 6169 is superior in material properties, microstructure, tensile mechanical properties, and salt spray test than the commercial materials 4032, 5052, 6061, especially the corrosion resistance. It is worth noting that the new type 6169 has high strength extrusion, which can be used as a reference for the future application of seashore industry, recreation parks, or building materials
