5052 aluminum coils is Aluminum-magnesium alloy aluminum coils.
Mg is the main alloying element in 5052 aluminum coils. It is the
most widely used rust-proof aluminum. The alloy is high in
nature, especially fatigue resistance, plasticity and corrosion
resistance, with high strength. It can not be heat-treated, the
plasticity of it is good in semi-cold hardening. It s low in
plasticity during cold hardening, and good in corrosion
resistance with good weldability, poor machinability and
polishing.
The main alloying element of 5052 aluminum sheet is magnesium,
and aluminum-magnesium alloy also contains a small amount of Mn,
Cr, Ni, Ti, etc. Most of the Mn in the alloy forms MnAl6 except
for a small amount of solid solution. In the interior of the 5052
aluminum coils, the effect of Cr is similar to that of Mn, which
improves the resistance to stress corrosion cracking, improves
the strength of the base metal and weld, and reduces the tendency
of weld cracking, but its content generally does not exceed
0.35%.
Surface Advantages of 5052 Aluminum coils:
1. surface of 5052 aluminum coils is not allowed to have cracks,
corrosion spots and traces of nitrate.
2. The surface is allowed to have peeling, air bubbles, surface
roughness. and it is also allowed to have local mechanical damage
with a depth not exceeding 8% of the nominal thickness of the
part where the defect is located. But the maximum depth of the
defect shall not exceed 0.5 mm, and the total area of the defect
shall not exceed the total area of the coils 5%.
3. Allow the supplier to illuminate the profile longitudinally to
a smooth surface.
4. Other requirements: There are demanders and suppliers to draw
up their own.
Application of 5052 Aluminum coils:
5052 aluminum coils is mainly used for high plasticity with good
weldability. It is also commonly used in transportation vehicles,
ship sheet metal parts, instruments, street lamp brackets and
rivets, hardware products, electrical enclosures, etc. It can
also be used to manufacture aircraft fuel tanks, oil pipes,
aerospace aluminum alloy materials, and is a typical rustproof
alloy material.
The atates of 5052 aluminum coils includes F, O, H12, H14,, H16,
H18, H19, H22, H24, H26, H28, H32, H34, H36, H38, H111, H112,
H114.
