Aluminum Alloy 1145 Foil Description
With a minimum aluminum content of 99.45%, Aluminum Alloy 1145 Foil is almost identical in chemical and physical properties. At times, certain production lots can be dual certified to 1145 and 1235 alloys. Like the 1100 alloy, both are considered commercially pure alloys and have excellent formability. The 1145 alloy has even better conductivity than 1100 due to its higher aluminum content. On the other hand, the 1145 alloy is becoming sparse in the market as many have found the 1235 alloy to be more readily available as it responds just as well in most applications.

Aluminum Alloy 1145 Foil FAQs
Q1 What are the key features of Aluminum Alloy 1145 Foil?
Aluminum Alloy 1145 Foil offers:
- High purity (≥ 99.45%)
- Superior corrosion resistance
- Excellent thermal and electrical conductivity
- High ductility and formability
- Non-heat-treatable but can be strengthened through cold working
- Recyclable and environmentally friendly
Q2 What are the common applications of ALF1463 Aluminum Alloy 1145 Foil?
This foil is commonly used in:
- Packaging for food, beverages, and pharmaceuticals
- Electrical and thermal insulation
- Heat exchangers and condensers
- Chemical processing equipment
- Reflective surfaces for lighting and insulation
Q3 How does Aluminum Alloy 1145 compare to other aluminum alloys like 1100 or 1050?
Aluminum Alloy 1145 has slightly lower purity than 1050 and 1100 but offers improved strength and excellent corrosion resistance. It is an economical choice for applications requiring high thermal conductivity and formability, without the need for extremely high purity.
