PM Industries is a manufacturer, supplier, and stockist of AMS 4152 7020 aluminum sheet and plate, a heat-treatable structural alloy that pairs high strength with low weight. 7020 belongs to the 7xxx series and draws its strength mainly from zinc and magnesium, with small additions of manganese, chromium, and zirconium that refine the structure. It is also known as EN AW-7020 and AlZn4.5Mg1. The alloy sits in a useful spot between the demand for light structures and the need for real mechanical durability. It carries a high strength-to-weight ratio and good resistance to fatigue under cyclic load, which is why it shows up in welded structures that take a beating over a long service life.

What sets 7020 apart from most other high-strength 7xxx alloys is how well it welds. Many strong 7xxx grades lose strength in the heat-affected zone and stay that way. 7020 ages naturally after welding and recovers close to its full strength in that zone over time, so welded joints hold up without a full re-treatment. The alloy also keeps reliable corrosion resistance across a range of demanding atmospheric conditions, and proper heat treatment gives it sound resistance to stress-corrosion cracking. That mix is a large part of why it is valued for long-term structural work.

The appeal for fabricators is range. 7020 machines well and cold-forms cleanly in the right tempers, so complex shapes can be made without giving up structural integrity. It does not take bright decorative anodizing well because of its chemistry, but it accepts protective anodized finishes that improve wear resistance and environmental defense. It also holds its dimensions under changing temperatures, which makes it a sound base for armor plate, heavy military vehicles, and high-load transport structures. Typical room-temperature reference values for 7020-T6 run near 350 to 385 MPa tensile strength, 280 to 320 MPa yield strength, and around 10 to 13% elongation, with a density of about 2.78 g/cm3. Actual values depend on thickness, temper, and product form, so confirm them against the mill certification.

Because it trims dead weight while keeping a high load-bearing margin, 7020 aluminum sheet and plate is used widely across heavy engineering. It is a staple in welded transport frames, railway carriages, mobile cranes, and structural bridges, where every pound saved feeds directly into energy efficiency. Its high fatigue strength and reliable stress-corrosion resistance also suit industrial machinery, armored defense structures, and aerospace parts such as radiator and heat exchanger assemblies. The combination of toughness, weld-recovery performance, and clean workability is what keeps this alloy in service across commercial, defense, and heavy transport systems.

When specifying 7020 aluminum sheet or plate, call out the required temper such as T6 or T651, the thickness and tolerances, the surface condition, and any certification tests you need, including chemical analysis, mechanical testing, and heat-treatment records. Clear callouts on these points keep the delivered material aligned with both design intent and procurement requirements.
