1. aluminum foil Category:
① according to the shape points, it can be divided into a roll of aluminum foil and a sheet of aluminum foil. Foil products delivery methods - like the vast majority of the volume, only a handful of users to use artisans packaging sheet of aluminum foil.
② Press thicknesses can be divided into thick foil, single zero foil, double zero foil three. Thick foil is a foil thickness 0.1-0.2㎜, single zero foil with a thickness of 0.01 mm and less than 0.1 mm foil, double zero foil, there are two zeros after the decimal point when the foil thickness mm for the units of measurement.
③ by state, major hard for the whole state of foil, foil soft state, semi-rigid foil state quarter and three-quarters of a hard foil hard foil.
④ Press the surface state can be divided into single-sided and double-sided foils foils.
⑤ according to zoning, divided foil packaging, household foil, electrical equipment and construction with foil with foil.

2. Foil properties:
Thin and light, than strength, good gloss, high thermal and electrical conductivity, high moisture resistance, non-toxic, tasteless, good cover optical, thermal insulation, good corrosion resistance.

3. aluminum and aluminum alloy grades and status:
In the past it is based on national unified representation that Pinyin plus a sequence number, since 1996, this representation has been disabled, is currently used in four-digit representation of the international system. Alloy uses a four-digit system of representation, wherein: the first representative of the alloy series, such as the first digit is 1, represents pure aluminum series, the first digit is 2-8, the representative of a the main alloying elements of different series of aluminum alloys. 1 Department represents aluminum, its last two digits indicate the minimum percentage amounts of aluminum in two after the decimal point. Indicates control of alloying elements or impurities limit the content of the second grade. Example: 1100 represents an aluminum content of 99.00%, 1235 represents aluminum content of 99.35%, 8011 Chemical composition: silicon content of 0.50 to 0.90, the iron content of 0.60 to 1.0, manganese copper content of 0.10 Mg 0.20 0.05 0.05 chromium content nickel content 0.10 Ti 0.08 Zn content, other content 0.05, total content of other 0.15, the balance aluminum content of 8011 (H14), mechanical properties: tensile strength: 125 to 165 yield strength: 110 elongation: 2 ~ 5.
4. The status of aluminum and aluminum alloys and code:
Baseline: F- free machining status, O- annealed condition, H- hardening state, W- solution heat treatment, T- heat treatment.
Subdivision Status: state foundation behind to pick 2-3 digits, the first digit is 1, 2 shows a basic processing program of the state, the basic state of the second digit indicates the degree of hardening products, digital 8 shows a hard state for state 8 between O (annealing) and H ×, should add a number from 1-7 indicates the alloy species and limit the use of aluminum foil, the main state O state respectively after H × code, H1 and H2 status state, other states rarely used.
