1, structural difference: aerospace aluminum is an aluminum alloy material with good plasticity and toughness. Due to the addition of a small amount of components, it can still maintain high strength and stiffness at high temperature. Honeycomb aluminum plate is a sandwich plate material, and the cardboard core is sandwiched between two metal surfaces. The special design of its internal structure makes it have good pressure resistance and fire resistance

2. Different performance differences: Space aluminum plate has high mechanical properties, such as high strength, high rigidity, corrosion resistance, smooth, firm and durable surface. In contrast, the structure of honeycomb aluminum plate determines its better energy absorption and acoustic performance, which is often used in lightweight, energy absorption and vibration reduction, sound insulation and noise reduction and other fields.
