3003 H24 Aluminum Foil Manufacturer
1. The first expression headed by the word 3 is: aluminum alloy with manganese as the main alloying element;
2. The word 0 in the second digit indicates that there is no special control over the limit content of impurities in this aluminum alloy;
3. The third and fourth digits 03 indicate the modified alloy, which does not have much practical connotation;
4. H represents products whose strength is improved through work hardening;
5. The 2 in 24 means the state of work hardening and incomplete annealing (that is, the product whose strength is reduced to the specified index by incomplete annealing after the degree of work hardening exceeds the specified requirements of the finished product) 4 means the middle of the O state to the 8 state That value.
Attachment: O state: the processed product with the lowest strength after complete annealing. 8 state: hard state of work hardening (super hard state is 9)
To sum up: 3003 refers to aluminum-manganese alloy, H24 refers to an aluminum substrate that has been incompletely annealed during the processing and rolling process to reach the specified strength and hardness index. In addition, there are aluminum-magnesium alloys with the 5 prefix series that are often used in aluminum-plastic panels, the other 4 prefix silicon series as the main alloying element, and the 7 prefix series with zinc as the element.
H24: Continuous casting and rolling, strong tension, local toughening.
Aluminum plate refers to an aluminum material with a thickness of 0.2mm or more to 500mm or less, a width of 200mm or more, and a length of 16m or less. It is called aluminum, and aluminum is less than 0.2mm. The width of the row or strip is equal to or less than 200mm (of course, as large The development trend of equipment, there are more and more aluminum materials with a maximum width of 600mm). Aluminum plate refers to a rectangular plate made of rolled aluminum ingot, which is divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, medium-thick aluminum plate and patterned aluminum plate.
Alloy aluminum plate is to add various alloying elements (the main alloying elements are copper, silicon, magnesium, zinc, manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc.) to improve the mechanical properties and Chemical indicators. Alloy aluminum plate has some special properties that pure aluminum plate does not have, and is widely used in special environments, such as ships, refrigerators, molds, aerospace equipment, etc., and can also be used in various industries.
