7150 Aluminum Plate

7150 aluminum plate is a high-strength aluminum plate produced using 7150 aluminum alloy. It belongs to the 7000 series of heat-treatable alloys and is primarily composed of zinc, copper, and magnesium. This alloy is specifically designed for aerospace structural components, offering an excellent balance of strength, fatigue resistance, fracture toughness, and corrosion resistance. While its strength is slightly lower than that of 7055, the 7150 aluminum plate performs better in thick-section properties, resistance to stress corrosion cracking, and overall reliability. It is widely used in critical aircraft parts that demand exceptional structural stability.

In the T7751 or T6151 temper, 7150 aluminum plate exhibits good quench uniformity, maintaining high strength and toughness even in large thicknesses. Typical applications include aircraft wing spars, wing skins, landing gear supporting structures, fuselage bulkheads, and frames. It is an ideal material for high-load and fatigue-resistant designs.

Chalco offers 7150 aluminum plates compliant with AMS 4252 (7150-T7751) and AMS 4306 (7150-T6151) standards, with a maximum width of 2650 mm and thickness up to 200 mm. Custom widths, fixed-length cutting, and machining services are available. Each plate is supplied with the original mill test report, ultrasonic testing, and third-party inspection certifications to meet the demanding requirements of aerospace manufacturing. Quick Quote

Performance of 7150 aluminum plate

What are Chalco's advantages as a 7150 aluminum plate supplier?

Equipment strength

Chalco is equipped with the German SMS (1+4) 4500mm hot rolling production line, utilizing Siemens electrical systems and the German IMS online shape meter, enabling closed-loop automatic control of thickness and plate shape.

The rolling mill is equipped with hydraulic adjustment, CVCplus control, bending roller system, regional cooling, temperature control system, as well as light shear, heavy shear, edge trimming, coiling, scrap recycling, and flue gas purification equipment, ensuring stable plate quality, minimal deformation, and flat plate shape.

Cold rolling capability

For cold rolling, Chalco uses the German SMS 2800mm single and double stand CVC cold rolling mills, with a maximum rolling force of 20, 000kN and a maximum rolling speed of 1800m/min.

The high-precision CVC system, combined with automatic thickness and shape control, ensures the 7150 aluminum plate has excellent surface quality and dimensional consistency, significantly reducing defects such as waviness and scratches, meeting the demands of aerospace and high-end manufacturing.

Production capacity

Chalco can produce ASTM B209 standard 7150 tempered aluminum plates with a maximum width of 4000mm and a maximum thickness of 250mm. For coils, the maximum width is 2650mm, and the minimum thickness can reach 1.8mm.

Custom products in various thicknesses, widths, and heat-treated conditions can be tailored to meet diverse engineering applications.

FAQ

What is the price of 7150 aluminum plate?

The price depends on the alloy temper, specifications, quantity, and the current aluminum ingot price. As an aerospace-grade material, 7150 is relatively more expensive than conventional aluminum alloys. Feel free to provide the specifications for a real-time quotation.

How to calculate the weight of 7150 aluminum plate?

Weight = Length (mm) × Width (mm) × Thickness (mm) × 2.83 × 10⁻⁶ (kg/mm³), where 2.83 g/cm³ is the theoretical density of 7150 aluminum alloy.

If you want to quickly calculate the weight of aluminum plates in other alloys, you can also use Chalcos online calculator.

Is the price of 7150 aluminum plate higher than 7075?

Typically, yes, it is slightly higher. Due to its superior corrosion resistance and performance in thick plates, 7150 aluminum plate adds more value in aerospace and high-end manufacturing sectors.

What surface treatments can be applied to 7150 aluminum plate?

Surface treatments such as anodizing, electrophoretic coating, spraying, and anti-corrosion coating can be applied to enhance appearance and improve corrosion resistance.

How is 7150 aluminum plate typically packaged and transported?

It is wrapped in waterproof plastic film and reinforced with fumigation-free wooden crates or pallets to ensure no surface scratches or oxidation during transportation, meeting requirements for sea and air shipments.

Common quality issues with EN AW-7150 aluminum plate

• Plate shape quality: 7150 aluminum plate is widely used in aerospace and high-precision structural components, requiring extremely high plate shape flatness. Improper process control during hot and cold rolling can lead to localized stress unevenness, causing surface waviness. This is particularly critical for ASTM B209 7150 T651 aluminum plates, as residual stress must be relieved through stretching to prevent deformation after cutting or shape changes during subsequent processing.
• Appearance quality: Due to the high surface quality requirements for 7150 aluminum plate, common appearance issues include warping, waviness, dents, scratches, edge burrs, or microcracks. These defects, especially in aerospace-grade materials, can directly affect product acceptance during delivery.
• Dimensional quality: Aerospace structural components have very strict dimensional tolerance requirements for thickness, width, and length. If thickness control during rolling is unstable or cutting/shearing equipment lacks precision, it may lead to out-of-tolerance conditions, risking scrap or rework.
• Surface quality: Common surface defects in 7150 aluminum plate include roller marks, roller scars, pulling marks, water stains, streaks, oxidation prints, black spots, and corrosion spots. These issues are often related to rolling speed, emulsification status, roller cleanliness, and annealing processes. Full-process monitoring and optimization of cleaning procedures are necessary to control these defects.
