1.質輕｜Light Weight
鋁的比重約為鋼、銅密度的1/3。
在油價高漲的時代，鋁在運輸工具及自動化設備之輕量化上扮演重要的角色。
Aluminium is a very light metal with a specific , about a third that of steel. 
For example, the use of aluminium in vehicles reduces dead-weight and energy consumption while increasing load capacity.

 2.耐蝕性｜Corrosion Resistance
鋁的氧化膜可阻絕空氣中之氧氣進一步氧化，具優良耐蝕性，可適用於室外或較惡劣之環境。
Aluminium naturally generates a protective oxide coating and is highly corrosion resistant. 

3.加工性｜Machining
鋁的加工性特佳，可加工成棒、線、擠型材等等……，供各種用途使用，尤其鋁的擠型性較其他金屬佳，擠型材在鋁的用量佔極大的比例，是極具市場潛力的材料。
Aluminium is very easy to machine. Ordinary machining equipment can be used such as saws and drills. Aluminium is also suitable for forming in both the hot and the cold condition.

4.表面處理｜Surface treatment
鋁的表面處理包括陽極處理、表面化成處理、塗佈及電鍍等，尤其陽極處理可生產各種不同色澤、硬度之皮膜，其特殊之光澤及顏色可增加產品外觀上之變化，而適用於各種用途。 
This surface treatment oxidizes the top layer of the aluminum, which is then compact and hard and is well-balanced with the basic material. The oxidized layer ensures excellent protection of aluminum against corrosion and wear.

5.可塑性｜Malleability
鋁加熱後具有良好的可塑性。
其中鋁擠型藉擠壓加熱之鋁合金錠進入模具後而自然定型，可依不同需求製造不同形狀產品，且生產長度適用於對長度有不同需求之工業產品。
Aluminium has a good malleability, a characteristic that is used to the full in extruding. Aluminium can also be cast, drawn and milled.

6.環保性/再生性｜Recyclability
鋁之價格雖較一般鐵、鋼高，但重熔後仍可重新使用，且取得容易，為目前最環保之金屬材料。
Aluminium is 100% recyclable without any loss of its natural qualities.
