With a minimum aluminum content of 99.45%, grade aluminum alloy 1145 with its sister alloy of 1235, are 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.
Grade aluminum alloy 1145 is more difficult to machine than most of the aluminum alloys. It is somewhat easier to machine in the H16, 18 or 19 tempers than in the softer or annealed temper.
Forming characteristics of AL 1145 are very good. All conventional forming methods may be used successfully with this alloy.
Weldability is very good by commercial methods, especially TIG or MIG welding.
AL 1145 is a non-heat treatable alloy. It is strengthened (hardened) by cold working.
Grade aluminum alloy 1145 Aluminium foil application
·1.Food Preparation: Aluminum foil is “dual-ovenable” and can be used in both convection and
fanassisted ovens. A popular use of foil is to cover thinner sections of poultry and meat to prevent
overcooking. The Henan Mintai also provides recommendations on limited uses of aluminum
foil in microwave ovens.
·2.Insulation: Aluminum foil is 88 percent reflective and is widely used for thermal insulation, heat exchanges
and cable liners. Foil-backed building insulation not only reflects heat, also provides a protective vapor barrier.
· 3.Electronics: Foil in electrical capacitors provides compact storage for electric charges. If the foil surface is
treated, the oxide coating works as an insulator. Aluminum foil capacitors are commonly found in electrical
equipment, including television sets and computers.
·4. Geochemical Sampling: Aluminum foil is used by geochemists to protect rock samples. Foil provides a seal
from organic solvents and does not taint the samples as they are transported from the field to the lab.
· 5.Art and Decoration: Anodizing aluminum foil creates an oxide layer on the aluminum surface that can accept
colored dyes or metallic salts. Through this technique, aluminum is used to create inexpensive, brightly colored foils.
