Abstract: As a kind of aircraft aluminum, 7075 aluminum plate is of extremely high
strength,which is widely used for aerospace, mold processing, auto parts, electronic appliances
such as smart phone shell. Welcome to learn more about it.
7075 Aluminum Plate for Mobile Phone Shell
In recent years, Apple mobile phones have been the industry benchmark, leading the trend of
mobile phone development.
Apple has been using an all-aluminum alloy body since the iPhone 5, because of its light weight,
high temperature resistance and gorgeous metallic luster. In addition, aluminum alloy is easier to
recycle, which is more in line with the contemporary environmental protection.
iPhone 6 is the last generation version of the Iphone6s in 2016 and was released in September
2014. The iPhone 6 uses the 6000 series aircraft aluminum sheet , but due to the insufficient
strength of the 6000 series alloy, it is easy to bend. Therefore, the iPhone 7 uses the higher-grade
7 series aluminum alloy.
The 7 series aluminum alloy is mainly made of zinc, and a small amount of magnesium and

2. copper are added. The hardness of the aluminum alloy is closer to the hardness of the steel,
which means that the iPhone 7's shell is less likely to bend, and the shell is more rigid.
The specific aluminum alloy is 7075 aluminum plate. It is a cold-treated forging alloy with high
strength, far better than mild steel. 7075 is one most powerful alloys commercially available.
Among this series, the 7075-T651 aluminum alloy is especially the top grade. It is known as the
best product among the aluminum alloys.
It has high strength and far better than any mild steel. This alloy also has good mechanical
properties and anodizing reaction. It has been used for the smart phone shell of OPPO N3 for the
first time in 2014. Now more and more smart phone manufacturers choose 7075 as the phone
shell. If you like to find a reliable 7075 aluminum plate supplier, welcome to leave message

7075 Aluminium Plate Thickness
7075 Aluminum plate, a main kind of aircraft aluminium sheet, is well known for high hardness
and strength, which is widely used in aerospace, mold processing, auto parts, electronic
appliances, automation and other fields.
According to the aluminium plate thickness, 7075 aluminum plate can be divided into 7075 thin
aluminium sheet, 7075 standard aluminium plate and 7075 thick aluminum sheet.
Among them, 7075 thin aluminum sheet is in T6 and TO temper, which is often used for for auto
parts, aviation parts, electronic product shells and other high-strength mechanical parts, etc. The
7075-TO aluminum sheet has good ductility and can be used in bending, stamping and other
processing fields.
7075 standard aluminum plate is divided into 7075 T6 and 7075-T651 aluminum plates. 7075-T6
aluminum plates are quenched aluminum plates
without pre-stretching, which is only suitable for
small-size parts processing. 7075-T651 aluminum
sheet is a pre-stretched aluminum sheet. It has
high hardness, no deformation and stable
anodizing effect.
The common temper of the 7075 thick aluminum
plate is T652. The thickness of 7075-T652
aluminum plate is generally greater than 200mm.
Most of them are used to make various molds or
large accessories. The 7075-T652 aluminum pate
is denser and harder than other tempers.
Haomei Aluminum has different thicknesses and
tempers of 7075 aluminum plate. Welcome to

What Will Affect The 7075 Aluminum Price
With small amount of copper, chromium and other elements, 7075 aluminum sheet has

3. extremely high strength, which is far better tan any mild steel. This aluminum alloy is widely used
in aerospace, mold processing, mechanical equipment,etc. There are three factor affecting 7075
aluminum price:
1. Production cost
and it has a high probability of failure. The production cost of the 7075 aluminium sheet is much
higher than that of 5052 aluminum plate and 6061 aluminum plate.
2. Technical factor
Since the 7075 aluminum plate has a high harness, it cannot be rolled by ordinary hot rolling mills.
Haomei Aluminum’s "1+1" hot rolling production line has been committed to the ingot casting
process and post-production of 7 series alloys, which will also be a qualitative leap for Haomei
Aluminum in the aluminum processing industry.
3. Market supply
Because of the production cost and
technical reasons, the supply of 7075
aluminum plate is very small, and the price
of 7075 aluminum plate naturally rises. If
the price of 7075 aluminium sheet is too low,
that is abnormal. Welcome to leave message

6061 Aluminium Sheet V 7075 Aluminum Sheet
6061 and 7075 aluminum sheet are two common aluminum alloys and widely used. There are an
analysis of their chemical element, mechanical properties, processing performance and price.
1. Chemical Element
Alloy Si Fe Cu Mn Mg Cr Zn Zr Ti Al
6061 0.4-0.8 0.7 0.15-0.4 0.15 0.8-1.2 0.10 0.10 - 0.10 Remainder
7075 0.4 0.5 1.2-2.0 0.30 2.1-2.9 0.18-0.28 5.1-6.1 0.05 0.20 Remainder
The main trace elements of 6061 aluminum plate are Mg and Si, forming the Mg2Si. A small
amount of copper or zinc is added to increase the strength of the alloy without significantly
reducing its corrosion resistance.
7075 aluminum plate has high content of trace elements. The main element is zinc that forms
Al-Zn-Mg-Cu with the addition of copper and magnesium.
2. Mechanical properties

4. 7075 aluminum plate is well known as aircraft aluminum,which is very superior in mechanical
properties. 7075-T6 is currently the highest strength aluminum alloy, which is better than
ordinary steel.
In industrial manufacturing, it is often used in occasions with higher standards, and its
advantages are self-evident. Not only the degree of precision is higher, but the service life is
longer.
In consumer electronics, Apple uses 7-series aluminum sheet for the middle and back covers of
iPhone phones. The Apple computer casing is
also made of all 7-series aluminum alloys. Other
smart phone manufacturers such as OPPO and
Xiaomi also uses 7075 aluminum plate.
In Equipment materials: In many special fields, it
has an irreplaceable advantage. For example, ski
poles and golf heads need to withstand the
impact of external forces repeatedly, so 7075
aircraft aluminum sheet is more preferred.
At present, more and more fields are trying to
use aircraft aluminum sheet to improve the
appearance and performance of products to
achieve differentiation from competing
products.
3. Processing Performance
 In terms of machinability, both can be milled well on CNC machine tools.
 6061 aluminum sheet can be welded, but 7075 aluminum plate is difficult to weld.
 6061 aluminum is suitable for the surface treatment such as anodizing or coloring. 7075 has
unstable anodizing effect.
 Without further processing, 6061 aluminum alloy has better corrosion resistance.
 Both 6061-T6 and 7075-T6 aluminum plate is of high hardness, which cannot be bent.

5. 4. Price difference
Generally speaking, the 7075 aluminum sheet price is about 20-40% more expensive than 6061
aluminum plate.
In conclusion, In most cases, 7075 aluminum plate is indeed superior to 6061 aluminum plate.
But we can't simply draw conclusions that 7075aluminum must be better. We still need to
consider the uses and the budget.
In general, 6061 aluminum sheet can basically meet the general industrial manufacturing
requirements. And 7075 is used in demanding occasions, such as aerospace, military products,
precision equipment, high-end electronic equipment,etc. As an aluminium sheet supplier, we
have both 6061 and 7075 aluminum plate. Welcome to leave message below to get a best price.
