What is 1070 Aluminum Grade?
1070 aluminum plate contains 99.7% Al, which is the alloy plate with the highest Al content among the 1xxx series of industrial aluminum. Therefore, 1070 aluminum alloy retains the excellent properties of pure aluminum itself, suitable extension processing, good thermal conductivity, high corrosion resistance, etc. In addition, by adding a small amount of alloying elements, the mechanical properties of 1070 aluminum plates are slightly enhanced.
Since 1070 aluminum does not contain other technical elements, the production process is single and the price is relatively cheap. It is currently the most commonly used series in conventional industries.
1070 is an aluminum grade that belongs to the 1000 series of aluminum alloys. Aluminum grades are designated by a four-digit number system developed by the Aluminum Institute. Each digit in the number represents a specific property or characteristic of the alloy.
Take 1070 aluminum grade as an example:
- The first number "1" means pure aluminum alloy with a minimum aluminum content of 99.00%.
- The second digit "0" indicates that it is part of the 1000 series, which includes pure aluminum alloys with excellent formability and high thermal and electrical conductivity.
- The last two digits "70" do not have any specific meaning and are used for identification purposes within the 1000 series.
1070 aluminum has relatively low strength compared to other aluminum alloys, so it is not typically used in applications requiring high structural integrity or load-carrying capacity.
In addition to aluminum, 1070 aluminum alloy also contains a small amount of impurity elements. These impurity elements are mainly iron, silicon, manganese and copper. Iron is the main impurity element, usually less than 0.25%. The presence of iron will reduce the strength and plasticity of aluminum alloys, but can improve the material's corrosion resistance.
- Silicon content is usually less than 0.20%. The presence of silicon can increase the strength and hardness of aluminum alloys.
- The manganese content is usually less than 0.03%. The presence of manganese can improve the corrosion resistance of aluminum alloys.
- Copper content is usually less than 0.04%. The presence of copper can improve the strength and plasticity of aluminum alloys.
1070 aluminum is known for its high electrical and thermal conductivity, good formability, and high reflectivity. It is commonly used in applications where these properties are required, such as electrical components, radiators, reflectors, and certain types of cookware.
