1145 Aluminium Foil Applications

Electrical Industry

1145 Aluminium Foil is extensively used in the electrical industry for capacitors, transformers, and other electronic components. The thickness and coating requirements vary based on the specific application, with a common thickness range of 0.02mm to 0.1mm.

Insulation

Aluminum foil is indispensable in the insulation of roofs and walls. Today, thermal insulation panels are made of solid polyurethane foam (PUR/PIR). Such panels are ideal for thermal insulation if they are additionally laminated with a top layer of aluminum foil.

In thermal insulation applications, thinner foils (0.01mm to 0.05mm) are used for their lightweight and reflective properties, contributing to energy efficiency in buildings and industrial settings.

Packaging

The malleability and corrosion resistance of 1145 foil make it ideal for packaging food, pharmaceuticals, and other consumer goods. Common thicknesses for packaging applications range from 0.012mm to 0.05mm.

Heat Exchangers

The alloy’s thermal conductivity makes it suitable for heat exchangers in various industries, with thicknesses typically in the range of 0.1mm to 0.2mm.

1145 Aluminium Foil Manufacturing Process

Casting: The process begins with casting Aluminium ingots, which are heated and transformed into rolling slabs.
Hot Rolling: The rolling slabs undergo hot rolling to form initial sheets of Aluminium.
Cold Rolling: The hot-rolled sheets are further reduced in thickness through cold rolling, creating the desired foil thickness.
Annealing: The foil is subjected to an annealing process, which enhances its flexibility and softness, making it more pliable for various applications.

Aluminium foil is a thin, flexible sheet of metal that has many uses in various industries and homes. Some of the most common applications of aluminium foil are:

Food packaging:

aluminium foil protects food from moisture, light and oxygen, maintaining its freshness and flavor. It can also be used for baking, toasting, grilling and reheating food.
