Китай 5052 Алюминиевая полоса катушки для крышки с вытяжным кольцом

5052 aluminum strip coil for ring pull can lid
1. Typical Products
5052 aluminum ring pull can lid strip: thickness: 0.22 - 0.5mm; width: 1280mm; 5052/5182: H19 alloy

2, Product Features
(1) Ring Pull stock generally adopts 5182 aluminum alloy processing, the Ring Pull Can Lid material generally use 5052 and 5182 aluminum alloys processed;
(2) flexible, stamping deformation is not easy to crack;
(3) small density, light weight, smooth surface, feel good;
(4) environmental protection is easy to recycle and reuse.
3. Main Quality Requirements
Surface processing is good, does not allow to have a black, marks, tire tracks, corrosion, pressure folds, creases, straightening roller printing, oil stain, stick injuries, scratches, metal and non metal pressed into etc. obvious defects, the strip flatness degree greater than 10I (or wave height is less than or equal to 3 mm, wavelength is preferably more than 400mm).

4. Production Control
(1) strict control of good width tolerance.
Thickness tolerance: + 0.01mm (preferably 0.005mm)
Width tolerance: + 1mm
Flatness requirements: height less than 3mm, within 1 meters of the wave number is less than 3;
(2). Mechanical properties:
Yield strength: 295-380Mpa;
Tensile strength: 355-420 Mpa;
Extension rate: 5.5%;
After baking: yield strength: 320MPa; tensile strength: more than 360MPa; the elongation rate: = 5.5%
(3). plate shape control:
Combined with roll, bending roll, spray the use of control good flatness, ensure hot machine convex degree control between 0.1 ~ 0.8%, hot online visual without obvious wave.
(4). appearance quality:
No end edge crack, roll end neat, no staggered pyramid.

5. Casting Process Control Points
(1) to control the content of Na, to avoid excessive sodium content, the emergence of sodium embrittlement (memory can be associated with the Nazis);
(2) note that the addition of gas, refined, to prevent the subsequent rolling of large cracks and cracks;
(3) note that in addition to the slag initial gas and other metallurgical quality, to prevent the use of the slag caused by the customer when the explosive tank.
