Aluminum Sheet and Foil 101

Manufacturing Aluminum Foil

Aluminum foil products are commonplace in the modern world – nearly everyone has a roll in their kitchen for cooking applications. Manufacturing aluminum foil was is a process that dates back to the early 20th century when small quantities of foil were produced by hammering. This method of manufacturing aluminum sheet foil was labor-intensive and took too long to be practical.

 

The Modern Foil Manufacturing Method

Over time, the foil manufacturing methods we use today were popularized. Modern foil is produced by rolling aluminum through a continuous mill which makes the aluminum thinner and longer. Thickness is reduced through this process and the aluminum product is wound into a coil at the end of the production line. These coils are then cold rolled in cold rolling mills. The coils can be heated in a furnace to soften it for further cold rolling or to produce the mechanical properties desired.

For some aluminum sheet products. cold rolling is the last step in the process. However, other types of aluminum sheet require more processing. In this case, they go through further elevated temperature processing in order to increase their strength.

Types of Aluminum Alloys

Like many metals, aluminum is available in several different alloys. An alloy is a mixture of metallic elements that can improve metal quality.

There are a great deal of aluminum alloys available, and selecting one means considering a variety details such as corrosion resistance, density, tensile strength, workability and more. Luckily, the experts at All Foils have been helping partners determine the ideal types of aluminum alloys for their unique applications for decades.

 

Gauge Sizes of Aluminum Sheet

Gauge is a measurement indicating the thickness of a sheet metal. Higher numbers refer to a thinner sheet and vice versa. Generally speaking, 000000 gauge aluminum sheet is the thickest measuring 14.732 mm while 40 gauge aluminum sheet is the thinnest measuring .079 mm.

All Foils has a variety of aluminum sheet on-hand ranging from 1.016 mm to .00508 mm in thickness or .040” to .0002”. We are happy to work with you to determine the appropriate gauge or thickness for your needs and discuss custom orders if your desired gauge is outside our current inventory.
