As a supplier of 2124 aluminum plates, what production equipment does Chalco possess?

Chalco owns world-class aluminum plate rolling and heat treatment equipment, including:

• Germany's SMS 4500mm hot tandem rolling production line, integrated with intelligent systems such as CVCplus control, roller bending control, thickness closed-loop system, and zoned cooling, ensuring stable plate shape and uniform thickness;
• 2800mm CVC cold rolling mill (single/double stand), with a maximum rolling force of 20, 000kN, ensuring surface quality and dimensional accuracy for medium-thick plates;
• High-precision stretching equipment and annealing furnaces, used to eliminate residual stress, ensuring dimensional stability of T851 condition plates after cutting and machining;

Complete supporting systems for edging, coiling, quality inspection, packaging, and environmental protection.

What are the common quality issues of EN AW-2124 aluminum plate?

Flatness issue: Plates that are not stress-relieved may warp or distort, especially during thick plate cutting. Chalco applies the T851 stretching process to effectively eliminate internal stress and ensure dimensional stability.

Appearance issue: Wave patterns, scratches, dents, and edge cracks may occur during hot or cold rolling. Chalco utilizes online flatness monitoring systems and imported precision-ground rolls to effectively control surface defects.

Dimensional issue: High-end structural components require strict tolerance control in thickness, width, and length. Chalco maintains thickness tolerance up to ±0.01mm and width deviation within ±1mm to ensure cutting and assembly accuracy.

Surface issue: Oxidation spots, roll marks, streaks, and corrosion may occur on the surface. We improve surface quality through cleanroom production, anodizing, and corrosion-resistant packaging to meet aerospace-grade standards.

The difference between 2124 aluminum plate and 2024 aluminum plate

2124 aluminum plate and 2024 aluminum plate are both widely used in aerospace, but they differ in key properties. Understanding these differences is essential when choosing the right material for specific applications.

Chalco's hot-selling 2124 aluminum plate series application fields

2124-O aluminum plate application

2124-O is in the annealed soft state, offering good plasticity and formability, making it suitable for processes that require further machining or heat treatment.

It is used for aerospace part preforming, deep drawing structural components, and blanks that require subsequent T state heat treatment.

2124-T351 aluminum plate application

The T351 state undergoes solution heat treatment, followed by stretching to relieve stress and natural aging, combining strength and machinability. It is suitable for structural components that require high strength but still need some formability.

It is widely used in aircraft fuselage structures, support frames, and fuselage segment connectors, where both strength and machinability are needed in aerospace structures.

2124-T851 aluminum plate

The T851 state undergoes solution heat treatment, stretching to relieve stress, and artificial aging, providing excellent fatigue resistance and fracture toughness, particularly suitable for high-stress areas.

It is used for primary load-bearing beams, wing skeletons, wing skins, fuselage bulkheads, and other high-safety areas, making it an ideal choice for critical structural components.

2124 aluminum plate purchasing guide

2124 aluminum plate weight

The weight of an aluminum plate is calculated based on its length, width, and density. For example, the density of 2124 aluminum alloy is 2.78g/cm³. The formula for calculating the weight is:

Weight = Length (mm) × Width (mm) × Thickness (mm) × 2.78g/cm³

This formula helps customers accurately assess logistics costs, container space, and transportation methods, providing important reference for project budgeting and transportation planning.

2124 aluminum plate price
