1070 aluminum alloy sheet
1070 aluminum alloy is widely used in electronics, electricity, construction, aerospace and other fields, such as protective nets for wires and cables, wire cores and aircraft ventilation system parts and decorative parts.
The European standard is EN AW-1070
UNS number is A91070
EN chemical name is Al99.7
1070 aluminum alloy belongs to the 1000 series of pure aluminum. It is the same as 1050 aluminum alloy, 1060 aluminum alloy and 1100 aluminum alloy, and the aluminum content is more than 99%.
| Alloy | Si | Fe | Cu | Mn | Mg | Cr | Zn | Ti | Ni | Other | AL |
| 1070 | 0.20 | 0.25 | 0.03 | 0.03 | 0.03 | —— | 0.07 | 0.03 | —— | 0.03 | 99.70 |
In addition to the aluminum element, 1070 aluminum alloy also contains a small amount of impurity elements. These impurity elements are mainly iron, silicon, manganese and copper.
Iron is the most important impurity element, usually containing less than 0.25%. The presence of iron will reduce the strength and plasticity of aluminum alloys, but can improve the corrosion resistance of the material.
The content of silicon is usually less than 0.20%. The presence of silicon can improve the strength and hardness of aluminum alloys.

The content of manganese is usually less than 0.03%. The presence of manganese can improve the corrosion resistance of aluminum alloys.
The copper content is usually less than 0.04%. The presence of copper can improve the strength and plasticity of aluminum alloys.
In addition to the above main components, 1070 aluminum alloy may also contain trace amounts of other elements, such as magnesium, zinc, titanium, chromium, etc. The content of these elements is very low, usually below 0.03%, and has little impact on the performance of the material.

1070 aluminum is used in many different industries due to its versatility; some common uses include automotive parts such as bumpers and wheels; aircraft parts such as fuselage frames; marine parts such as boat hulls; industrial fasteners such as bolts; Food containers; medical equipment; sporting goods and more!
1070 aluminum sheet for car
1070 aluminum is popular for automotive parts due to its high strength-to-weight ratio, low cost, and corrosion resistance. It can make engine blocks, cylinder heads, pistons, connecting rods, crankshafts and other parts that require strength and durability. Additionally, due to its lightweight properties, aluminum 1070 is often used in the manufacture of wheels.
Alloy 1070 is also widely used in construction applications such as window frames, door frames, curtain walls and roof panels. Its light weight makes it easy to install and transport, while its corrosion resistance ensures it will last for many years without maintenance or repairs. In addition, AL1070 has excellent thermal insulation properties, helping to keep buildings cool in hot weather.
Due to its excellent electrical conductivity, 1070 aluminum is commonly used in the manufacture of electrical components such as switches and circuit breakers. The metal’s low cost makes it a popular choice for large projects, such as power lines and transmission towers that require hundreds or thousands of components. Because UNS A91070 can absorb light efficiently, it can also be used to build solar cells for photovoltaic systems.
Alloy AL 1070 is commonly used in the manufacture of food processing equipment such as conveyor belts and cookware due to its non-toxic properties and ability to resist corrosion from acids such as vinegar or lemon juice. The metal is lightweight and can also be easily moved around large factories or warehouses where food processing is frequent.
Aluminum A91070 has excellent resistance to salt water corrosion, making it ideal for marine applications such as boat hulls and propellers. The metal’s strength-to-weight ratio also makes it ideal for ship masts, which must be lightweight yet strong enough to support sails in rough seas. Additionally, AL Alloy 1070 can be polished easily, making it ideal for luxury yachts where aesthetics are of paramount importance.
