Hot rolled aluminum plate is an aluminum alloy sheet produced through a hot rolling process. The hot rolling process involves heating aluminum ingots to a specific temperature at high temperatures, then pressing and shaping them using a rolling mill. This process refines the grain size of the aluminum, improving its strength and toughness, while also enhancing its plasticity and processing performance.
Specifications of hot rolled aluminum plate:
Hot rolled aluminium plate is produced using a high-temperature rolling process, offering a wide range of specifications to meet the needs of various industries:
– Thickness:
Typically 0.8mm-600mm, with standard thicknesses ranging from 10mm-450mm. Extra-thick aluminum plates can reach 600mm, suitable for high-strength structural components.
– Width:
Standard widths range from 1000mm-2200mm, with a maximum of 2800mm, meeting the needs of wide-format curtain walls, shipbuilding, etc.

5005, 5052, 5083, 5086, 5754: Aluminum-magnesium alloy, high strength, resistant to seawater corrosion, suitable for ships and pressure vessels.
6061, 6082, 6063: Aluminum-magnesium-silicon alloy, heat-treatable, used in aerospace and automotive structural components.
7075: Ultra-hard aluminum alloy, high wear resistance, used in high-stress components.
Characteristics of hot rolled aluminum plate:
Hot rolled aluminum plates, due to their technological advantages, possess the following characteristics:
– Excellent surface quality:
High-temperature rolling results in a high surface finish and good oxidation effect, allowing for direct use for decoration or further processing.
– High mechanical properties:
Tensile Strength: 1060 aluminum sheet has a tensile strength of 110-136 MPa, with alloy series reaching even higher strengths (e.g., 5052 can reach 230-280 MPa).
– Dulleriness:
Suitable for complex processing such as stamping, deep drawing, and bending, with good formability.
– Corrosion resistance:
A dense oxide film forms on the surface, effectively preventing corrosion, suitable for humid and acidic environments.
– Lightweight:
Density is only 2.7 g/cm³, about 1/3 that of steel, significantly reducing structural weight.
– Low work hardening:
The softening process dominates during hot rolling, resulting in low deformation resistance, low energy consumption, and high production efficiency.
