Do You Know the Difference of the Aluminum Sheet/Plate and Foil - toyota1515 - 03-13-2018 When it comes to the aluminum materials, these words are not strange to you, such as the aluminum sheet, aluminum plate, aluminum foil, etc.. Because they are all made of the aluminum, so they have the same character, and you maybe wonder what is the difference between them, and today we will talk about it. In a word, the difference of them is the thickness, for example, the extremely thin thicknesses are considered foil or leaf, the aluminum foil is a solid sheet of aluminum (or alloy rolled to a thickness of 0.0059 inches or less). At a thickness of 0.006 inches or more it is referred as sheet and thickness more than 6 mm (0.25 in) is considered as plate. The application in different fields may need the different thickness, and you may need to be clear about the using purpose when you are buying the aluminum sheet or foil. If you consider them as the same, there maybe some trouble with you. RE: Do You Know the Difference of the Aluminum Sheet/Plate and Foil - aluhm - 12-07-2018 The difference between metal sheet, plate and foil is the thickness of the metal, with foil being the thinnest and plate being the thickest, but the boundaries vary depending on who you are talking to and the material you are talking about. I believe the thickness limits developed from the use of a gauge number (gage number in USA) number to specify sheet metal thickness, with metal thicker than the size range covered by the gauge standard being termed plate and metal thinner than the size range covered by the gauge standard being termed foil. A number of different gauge standards have been used for different applications. For example, gauges for ferrous metals (steels) are not used for non-ferrous metals such as aluminium and copper alloys, and there are also regional preferences for alternative gauges. Depending on the historical application of the various gauges to describe sheet metal, and their thickness limits, or simply local practice, the thickness at which metal is described as foil, sheet or plate is different. Confusingly, the same gauge number refers to a different thickness in different gauge standards. Due to this potential for confusion, the use of gauge number is discouraged by current standards organisations such as ASTM, “as being an archaic term of limited usefulness not having general agreement on meaning” (ASTM A480/A480M (08b). For a definitive answer, it is necessary to refer to a standard or specification recognised by the manufacturer of the metal product in question (so it does still depend on who you are talking to). For example, stainless steel can be purchased in compliance with the specifications of ASTM A480/A480M (08b) - Standard Specification for General Requirements for Flat-Rolled Stainless Heat-Resisting Steel Plate, Sheet, and Strip. This includes the following definitions for material complying with this standard: Plate: material 3/16″ [5.00 mm] and over in thickness and over 10″ [250 mm] in width; Sheet: material under 3/16″ [5.00 mm] in thickness and 24″ [600 mm] and over in width; Strip: cold-rolled material under 3/16″ [5.00 mm] in thickness and under 24″ [600 mm] in width. Note that the metric dimensions are not conversions of the imperial measurements: they are the measurements used by the metric version of the standard, ASTM A480M. This does not mean that all stainless steel of thickness 3/16″ and over must be called plate, but it is the correct term for material complying with this particular standard. Since ASTM A480/A480M does not include requirements for metal foil, it does not define a boundary between foil and sheet. A different standard would need to be specified for stainless steel foil, and this standard would define the thickness of material that it covered. Different standards would also need to be specified for other metals, and they may well define the sheet and plate thickness limits differently (for historical reasons, such as the gauge standard previously used). RE: Do You Know the Difference of the Aluminum Sheet/Plate and Foil - Tyeshacon - 12-07-2018 Plate and sheet are words used to describe the classification of metal depending upon its thickness. While sheet metal is less than 3 mm thick, plate metal is obviously thicker than 3 mm. Many people become confused because of classifications such as plate, sheet, foil and others, but there is no need to be, as their differences are clearly spelt out. It is mostly in terms of metal aluminum that we hear words like plate and sheet. The thickness of the product decides the category into which it falls or belongs. Plate is defined as a thickness of more than or equal to 0.25 inches, while a sheet has a thickness of 0.006 inches or more but less than 0.25 inches. At the extreme of this continuum is a foil that has a thickness of less than 0.006 inches. RE: Do You Know the Difference of the Aluminum Sheet/Plate and Foil - askaluadmin - 12-07-2018 As aluminum moves between rolls under pressure, it becomes longer and thinner, thus resulting in Aluminum Plate or sheets. One of the main differences between Aluminum Plate and sheets is that sheet metal is under .249” thick, while plate metal is .250” and above.. Another difference between Aluminum Plate and sheets has to do with the distinct applications for which they are used. Sheets Sheet is the form of aluminum that is used the most often. You can find it in all of the major markets of the aluminum industry. For instance, aluminum sheet is useful for manufacturing packages and cans in the packaging industry. It is also valuable for manufacturing tractor trailers and automobile body panels in the transportation industry. Sheets are also useful for cookware and home appliances, as well as for construction/building products, such as carports, awnings, roofing, gutters, and siding. Sheet aluminum can even be given blue, red, gold, or black colors, for instance, through color anodizing. It can also be etched to feature a matte finish, or be polished to feature a bright, sparkling appearance. Aluminum sheets may additionally be made to resemble wood through texturing. Plates Aluminum plate is the most often used for heavy-duty applications, particularly in the transportation product manufacturing, aerospace and military industries. Since certain aluminum alloys have the potential to become more durable at extremely cold temperatures, Aluminum Plate serve as the skin of spacecraft fuel tanks and jets, and can also be useful for storage tanks. Moreover, you can use Aluminum Plate in the manufacture of structural sections used in ships and railcars and for military vehicle armor.

RE: Do You Know the Difference of the Aluminum Sheet/Plate and Foil - aadaasdark8072 - 12-07-2018 Plates are basically a part of Sheets. Sheets are industrially flattened out pieces of metal. Sheets are used in a wide array of applications and can be cut, as well as bent in to a variety of shapes. Extremely thin pieces of sheets are called as foils and thicker are considered as plates. In most parts of the world millimetre is used as a measuring unit for Sheets/Plates, whereas Gauge is used in the US to measure Plates/Sheets. 30-7 gauge is the general range used where larger the measure, thinner is the Sheet/Plate RE: Do You Know the Difference of the Aluminum Sheet/Plate and Foil - haomeialu - 12-07-2018 Plate is defined as a thickness of more than or equal to 0.25 inches, while a sheet has a thickness of 0.006 inches or more but less than 0.25 inches. At the extreme of this continuum is a foil that has a thickness of less than 0.006 inches. These are the three categories that form a bulk of aluminum used in the country in various industries. Aluminum is passed between rolls under extreme pressure to make it thinner and longer in the direction in which it is moving. The amount of pressure that is applied decides which of the three categories the resulting aluminum product will belong. This rolling process can be carried out again and again to turn aluminum into a shape and size which is desired. Rolling process is stopped as soon as we get the desired gage or thickness of aluminum RE: Do You Know the Difference of the Aluminum Sheet/Plate and Foil - 1-LVDCPN - 12-07-2018 Aluminum sheet and aluminum plate are both widely used and respected due to the metal’s light-weight strength, along with high corrosion resistance. But what is the difference between sheet, plate, and foil? When choosing between the three types of products, the only difference is the thickness – with plate being thickest and foil the thinnest. However, the exact thicknesses separating the categories depend upon the application, the metal in question, the gauge, and product specifications. Independent & Inconsistent Metal Standards Historically, gauges were the standards used to specify the thickness of metal wires before new, more accurate measurement technology was developed. Each industry created its own standards independently, and as a result, gauge numbers vary for aluminum, copper, brass, and different types of steel. For example, the Dictionary of Units of Measurement defines 10 gauge aluminum as being 0.1019 inches thick, while 10 gauge standard steel is 0.1345 inches and a 10 gauge galvanized steel is 0.1382 inches. As a result of this confusing state of affairs, the American Society for Testing and Measurement (ASTM) says in specification ASTM A480-10a, ‘The use of gage number is discouraged as being an archaic term of limited usefulness not having general agreement on meaning.’ Modern Metal Thickness Measurements The common practice today is to specify the exact thickness of the product in question, thought the gauge may also be listed. In the case of aluminum and its alloys, sheet is typically defined as a piece of metal that is less than 0.249 inches thick. Aluminum plate is 0.25 inches and thicker, while aluminum foil is defined as anything thinner than 0.006 inches. Due to their superior physical properties, aluminum sheet and plate are sought after for many different industrial applications. Aluminum plate is used for heavy-duty and structural applications, such as aerospace, military, and rail and sea transportation. Aluminum sheet is the most common form of the metal, and is used in a wide range of industries, from food & beverage canning to cookware, appliance, and auto manufacturing. It is especially useful for construction of roofing, gutters, and siding. Contact Industrial Metal Supply for your aluminum sheet & plate needs, or if you have questions.
