Álpappír og álspóla eru bæði fjölhæf álefni sem notuð eru í mismunandi notkun í ýmsum atvinnugreinum. Álspólublendi og álpappírsblendi hafa svipaða eiginleika á mörgum sviðum, en hafa líka marga mismunandi eiginleika. Huawei mun gera nákvæman samanburð á þessu tvennu hvað varðar eignir, notar, o.s.frv.:
Álpappír: Aluminum foil is a thin sheet of aluminum, typically less than 0.2 millimetrar (mm) þykkt. It is commonly used for wrapping food, umbúðir, insulation and cooking. Aluminum coils: Aluminum coils are continuous rolls of aluminum sheets commonly used in industrial applications such as roofing, byggingu, automotive and manufacturing.
Álpappír: Aluminum foil is very thin, typically 0.006 mm til 0.2 mm (6 microns to 200 míkron). It is available in various thicknesses depending on the specific application.
Álspóla: Aluminum coil is thicker than aluminum foil. Their thickness ranges from approximately 0.2 mm to several millimeters, depending on the intended use.
Álpappír: Aluminum foil is typically produced by rolling aluminum ingots through rolling mills to achieve the desired thickness. The foil is then annealed and may undergo additional treatments for specific properties.
Aluminum Coils: Aluminum coils are produced in a similar manner to aluminum foil but are typically thicker and wider. The process involves hot or cold rolling of aluminum ingots or billets through rolling mills to produce continuous coils of various thicknesses and widths.
