5083 H131 H11 Aluminum Sheet for Tanker

5083 aluminum alloy belongs to the Al-Mg alloy family. The addition of magnesium gives it many core properties suitable for tank truck applications:

Firstly, its exceptional corrosion resistance is crucial for tank trucks that frequently transport chemical liquids, food-grade materials, or operate in harsh outdoor environments. 5083 aluminum sheet resists corrosion from seawater and acidic and alkaline solutions, preventing safety incidents caused by corrosion and leakage, significantly extending tank truck maintenance cycles.

Secondly, it offers balanced strength and plasticity, with a tensile strength of 300-350 MPa. This allows it to withstand the pressure of the medium inside the tank while also possessing sufficient formability to meet complex processing requirements such as rolling and stamping tank heads.

Another advantage is its lightweight. Compared to traditional carbon steel, 5083 aluminum sheet has a density of only 2.66g/cm³. Using it to manufacture tank truck bodies can reduce vehicle weight by 15%-20% while maintaining strength, directly reducing fuel consumption and increasing cargo capacity, meeting the current logistics industry's demand for cost reduction and efficiency improvement.

5083-h131

5083 h131 process involves increasing the material's hardness through cold rolling, followed by low-temperature stabilization to eliminate internal stresses and ensure stable performance. Its yield strength achieves 210-260 MPa, offering higher hardness, strong deformation resistance, and excellent dimensional stability.

It resists plastic deformation even under long-term tank pressure. It also retains the corrosion resistance of the 5083 series, effectively resisting corrosion even when transporting slightly corrosive liquids (such as weak alkaline solutions and salt water).
It is primarily used in critical pressure-bearing areas of tank trucks, such as the midsection (which withstands the longitudinal pressure of the medium), the inlet and outlet flange connections (which must withstand the impact pressure during loading and unloading), and the head reinforcement layers of some high-pressure tank trucks, ensuring the structural safety of the tank trucks during full transport.

5083-h11

5083 h11 is the product of "work hardening followed by natural aging." Compared to H131, it reduces the stabilization process and prioritizes a balance between plasticity and strength. Its yield strength is slightly lower than that of H131 (approximately 180-220 MPa), but its elongation is higher (up to 15%-20%).

It is less susceptible to cracking during bending and stamping, making it particularly suitable for machining complex curved surfaces. Its corrosion resistance is also unaffected, meeting the hygiene and corrosion protection requirements of food-grade tank trucks (e.g., those transporting milk and cooking oil).

It is mostly used for "special-shaped parts" of tank trucks, such as tank heads (which require deep stamping), tank truck side guardrails (which need to be bent into an arc shape), and bottom support structures (which require multi-angle welding and forming). This can not only ensure the structural strength of the parts, but also reduce processing difficulty and scrap rate.
