Aluminum Armor Plate

Chalco armor plates have strict quality control and meet standards such as MIL-DTL-32341, MIL-DTL-45225, MIL-DTL-46027, MIL-DTL-46083E, MIL-DTL-32375B, GJB 9614-2019, and GJB 1540-2021. Chalco can provide multiple quality inspections if needed.

Chalco's latest composite armor plate product

Aluminum alloy layered composite armor plate can also be referred to as a "sandwich structure" plate. It is composed of aluminum alloys with higher strength and aluminum alloys with lower strength but better toughness and weldability. The hard layer panel has bulletproof ability, the resilient layer back plate can prevent debris from peeling off, and the separation of the interface between the panel and interlayer can absorb energy in layers. The overall penetration resistance is higher than that of homogeneous armor, and the explosion-proof performance is better.

Chalco first generation armor plate products

Early armored vehicles were mainly made of steel. With the increasing demand for protective capabilities of armored vehicles in modern warfare, ideal armor materials also need characteristics such as lightweight, impact resistance, high mobility, and corrosion resistance. As the first generation of lightweight armor plates, aluminum alloy plates such as 5083, 5456 were developed and applied under this demand.

Chalco second generation armor plate products

Most of the first generation aluminum alloy armor plates cannot be strengthened by heat treatment and have poor resistance to direct impact from small caliber projectiles, making it difficult to meet the protection requirements. Chalco second-generation armor plate alloys such as 7039, 7056, 7020, 7017 have made up for these deficiencies and are used to resist high-speed shrapnel, warheads, explosive impacts, and other threats.

Chalco third generation armor plate products

To address the ballistic and stress corrosion resistance of aluminum alloys, Chalco third-generation armor plate alloys such as 2519, 2139, 2195 have been introduced, which have higher mechanical properties, ballistic resistance, weldability, and stress corrosion resistance.

The importance of replacing steel with aluminum in armor plate

• Aluminum has low density and good mechanical properties, which can reduce the weight of armored vehicles and increase driving speed while improving structural stiffness;
• Aluminum has high strength and toughness, with comprehensive performance of anti-penetration and anti-fragmentation;
• Aluminum has better processing performance and is suitable for mass production;
• Aluminum has stronger welding performance, which better adapts to the manufacturing of different models of armored vehicles;
• Aluminum has stronger thermal nuclear resistance, which can effectively protect personnel inside the vehicle from radiation damage.

Choose Chalco as the supplier for the armor plate project

Chalco hot rolling project utilizes the German Sigma (1+4) 4500mm continuous rolling line, and the cold rolling project uses the German Sigma six-high cold rolling mill.

Chalco armor plate product quality inspection

Unlike other functional aluminum plates, armor plates have higher and stricter quality requirements due to the unique nature of their use areas. Chemical composition, strength, hardness, processability, and corrosion resistance must be strictly controlled during and after production.

Chalco product development and production are within the MIL-DTL standard range, and can provide finished product testing to ensure quality meets customer requirements.

Initial product inspection testing methods

• Chemical composition: extract samples for chemical analysis from each plate selected for ballistic testing.
• Mechanical performance: extract tensile test samples from each board selected for ballistic testing.
• Ballistic testing: according to the standards in the standard attachment, two 12x36 inch plates of each thickness provided in the contract are taken for ballistic testing.
• Stress corrosion test: the stress corrosion test samples are extracted from the same plate selected for ballistic testing.

Product compliance inspection testing methods

• Chemical composition: when tested according to the provisions of this standard, the sample must meet the chemical composition requirements.
• Mechanical properties: for tensile testing, samples are randomly selected from different plates in the batch, and only one tensile test sample is taken from each sample.
• Ballistic testing: randomly select a 12x36 inch plate from each batch for ballistic testing.
• Stress corrosion test: randomly select a 12x12 inch plate from each batch for this test.
