The main alloy element of the 3 series aluminum sheet is manganese, collectively called aluminum magnesium manganese aluminum sheet, representing alloys 3003, 3004, 3005, 3104, 3105, 3A21. Due to the presence of manganese, this series of aluminum alloys have excellent rust resistance, and are often used as rust-proof aluminum plates for areas requiring high rust resistance. 3003 h14 aluminum sheet is one of the tempers of 3003 aluminum sheet, and it is also a high quality aluminum alloy.

What does h14 in 3003 h14 aluminum sheet stand for?

Many people are not very clear about the numbers behind the aluminum plate. Here we will use 3003 h14 aluminum sheet as an example to explain to you. H represents the temper of cold work hardening, and the following figures indicate the different degrees and types of cold work hardening. The first digit after H indicates the basic treatment procedure for obtaining this temper, and H1 is the simple work hardening temper. Applicable to tempers without additional heat treatment, and only after working hardening to obtain the required strength. The second digit after H indicates the work hardening degree of the product. The larger the number, the higher the hardness. The tensile strength limit of 3003 h14 aluminum sheet is the middle value between O and h18 state.

3003 anti-rust aluminum plate has temper temper H111, H112, H12, H14, H16, H18, H19, H22, H24, H26 and H28. The hardness will be different in different tempers. The hardness of 3003 h14 aluminum sheet is 46, the elongation is 2 ~ 5 (different according to different thickness), the yield strength is 125, and the tensile strength is 145 ~ 185.

3003 h14 aluminum sheet for curtain wall aluminum plate

One of the common applications of 3003 h14 aluminum sheet is for curtain wall aluminum sheet. Building decoration materials are often affected by external factors such as wind and rain, so they need to have good anti-rust properties. Its raw materials must also have the same performance.

3003 aluminum sheet and 5052 aluminum sheet have good corrosion resistance, close to industrial pure aluminum, and have good corrosion resistance to seawater, organic acids, gasoline, and other solutions. However, considering the economic practicability, the 3 series is often used. The treated curtain wall aluminum plate has excellent corrosion resistance and resistance to various air pollutants, which makes the curtain wall aluminum plate widely used in many buildings.
