Aluminum Coil 5A03

5A03 aluminum sheet is the most commonly used material in the construction field, and also belongs 5 series Al-Mg antirust alloy. In terms of composition, the Mg content of 5A03 aluminum is slightly higher than that of 5754 aluminum alloy, so 5A03 aluminum sheet corrosion resistance and tensile strength are higher than those of 5754 alloy. And due to the addition of a small amount of Si, 5A03 aluminum alloy has better weldability than 5754 and 5A02 alloy.

5A03 Aluminum Plate Features:

Significant Weldability. Due to the Si content, 5A03 aluminum sheet has better weldability than 5754, 5A02 alloy, and is suitable for gas welding, argon arc welding, spot welding and roll welding, etc. At the same time, a small amount of Si also increases the strength between welds, and reduces the crack tendency.

Strong Weather Resistance. Even below 0℃, 5A03 aluminum sheet strength won’t decrease with the decrease of temperature, but will increase, with excellent fatigue strength. There's no low temperature brittleness.

Mechanical Proprties. 5A03 aluminum sheet tensile strength σb (MPa)≥172, elongation δ5 (%)≥12,conditional yield strength σ0.2 (MPa)≥81.
