Some of the knowledge of the Pearl Foil
Bead foil - in the daily production of Pearl Foil in the application of the majority of users recognized, the use is also very wide.
1. Definition of Pearl Foil:

The bead foil is a very thin aluminum coil, strip or sheet obtained by rolling the aluminum and aluminum alloy strip rolls. In China, the thickness of less than 0.2 mm of aluminum and aluminum alloy plate is called Pearl Foil.
2. Classification of Pearl Foil foil:

① by the shape of points, can be divided into roll Pearl Foil and flake Pearl Foil foil. Porcelain foil products are available in the majority of the volume, only a handful of handicraft packaging users use flake Pearl Foil foil.
② by thickness, can be divided into thick foil, single zero foil, double zero foil three. Thick foil is the thickness of 0.1-0.2 mm foil, single zero foil is the thickness of 0.01 mm and less than 0.1 mm foil, double zero foil is the thickness of the unit for the measurement of the decimal point after the two zero foil.
③ by state, mainly for the hard state foil, soft state foil, semi-hard state foil, quarter hard foil and three quarters of hard foil.
④ according to the surface state can be divided into single-sided optical foil and double-sided optical foil.
⑤ According to the use of points, divided into packaging foil, daily necessities foil, foil for electrical equipment and building foil.
3. The nature of the Pearl Foil:

Thin, light, high strength, better gloss, high thermal conductivity and conductivity, high moisture resistance, non-toxic, tasteless, good light-blocking, heat insulation, good corrosion resistance.

4. Aluminum and aluminum alloy grades and status:

In the past, the use of domestic uniform representation, that is, the Chinese Pinyin plus sequence number, since 1996, this representation has been disabled, the current use of the international four-digit system that way. The grade of the alloy is a four-digit system representation, where: the first representative of the alloy series, such as the first digit is 1, it stands for pure aluminum series, the first digit is 2-8, Alloying elements consisting mainly of different series of aluminum alloys. 1 series represents pure aluminum, and the last two digits indicate the lowest of the zero percent of the decimal point. The second position of the grade indicates the control of the alloying element or impurity limit. For example: 1100 means that the aluminum content of 99.00%, 1235 for the pure aluminum content of 99.35%, 8011 Chemical composition: silicon content 0.50 ~ 0.90, iron content 0.60 ~ 1.0, copper content 0.10 manganese content 0.20 magnesium content 0.05, chromium content 0.05 nickel content Zinc content 0.10 Titanium content 0.08, other content 0.05, other content total 0.15, aluminum content of the remaining 8011 (H14), mechanical properties: tensile strength: 125 ~ 165 yield strength: 110 elongation: 2 ~ 5.
 5. Aluminum and aluminum alloy status and code:

Basic state: F-free machining state, O-annealing state, H-work hardening state, W-solution heat treatment state, T-heat treatment state.

Subdivision state: the basic state to be followed by 2-3 digits, the first digit is 1,2,3,4 that the state of the basic processing procedures, the basic state of the second digit that the degree of hard work, 8 indicates a hard state. For the state between O (annealing) and H × 8, the numbers from 1 to 7 are added after H × code, respectively, and the main state is O state due to the limitation of the alloy type and the use of the bead foil , H1 state and H2 state, other states rarely used.
