3003 H24 aluminum foil is a highly versatile semi-rigid aluminum-manganese alloy foil used in industrial applications. Its balanced performance in terms of strength, formability, and corrosion resistance makes it a core material in the global packaging, electronics, construction, and transportation industries. Leveraging large-scale production and years of overseas export experience, Haomei Aluminum’s customized 3003 H24 aluminum foil overcomes the performance limitations of ordinary aluminum foil, its process stability and quality control standards meet market access requirements, making it a highly adaptable and cost-effective industrial-grade aluminum foil.
3003 H24 aluminum foil is one of Haomei Aluminum’s core export products. It is made from an Al-Mn rust-resistant alloy (manganese content strictly controlled at 1.0%-1.5%), and is a semi-rigid foil formed through cold rolling and stabilization treatment, achieving a precise balance between strength and formability. Our standard production specifications cover thicknesses from 0.02mm to 0.20mm (20-200μm) and widths from 200mm to 1600mm. Custom cutting sizes are available upon request, with rolls being the primary supply. Regarding key tolerance control, thickness deviation is consistently within ±3%, width tolerance is ±1mm, pinhole density is ≤2 pins/m², and surface roughness Ra is ≤0.3μm, far exceeding international standards such as ASTM B209, EN 546, and GB/T 3198 (HAOMEI Aluminum Foil, Inc.). Our production process employs semi-continuous casting + multi-pass cold rolling + online stabilization annealing, ensuring uniform mechanical properties and surface quality in each roll of foil.
The core advantage of customized 3003 H24 aluminum foil lies in its balanced performance and processing stability, stemming from its unique alloy composition and heat treatment process.
In terms of mechanical properties, the tensile strength in the H24 state reaches 180-210MPa, the yield strength is 170-200MPa, and the elongation is ≥5%, representing an approximately 80% increase in strength compared to the O state, while retaining sufficient formability, making it particularly suitable for complex stamping and bending processes.
Regarding corrosion resistance, the dense oxide film formed by manganese provides excellent resistance to atmospheric and chemical corrosion, exhibiting stability in environments with a pH of 4-9. It has passed FDA/EFSA food contact certification, making it an ideal material for food containers and packaging.
In terms of processing characteristics, we employ a slot-type extrusion oiling technology to form a uniform lubricating film of 150-400mg/m² on the foil surface, maintaining a stable coefficient of friction of 0.08-0.12. This extends the die life of high-speed stamping lines (200 times/minute) for North American customers by 40% and reduces downtime for die changeovers by 50%.
In addition, this foil also possesses excellent thermal conductivity (approximately 190W/m・K) and solderability, adapting to various joining processes and providing flexibility for downstream manufacturing.
Based on our more than 25 years of export experience, the application of 3003 aluminum foil covers four core areas: food packaging, honeycomb structures, electronic components, and building sound insulation. The following are typical applications and customer cases for Haomei Aluminum:
– Food Container Sector:
50-80μm specifications are the preferred material for fast food boxes, baking trays, and disposable tableware. Our pre-lubricated 3003 H24 foil, customized for a North American chain restaurant giant, solved the cracking and sticking problems during high-speed molding. Monthly supply exceeds 500 tons, and the finished product qualification rate has increased to 99.7%. (HAOMEI Aluminum Foil, Inc.) This foil has a temperature range of -20℃ to 220℃, suitable for refrigeration, microwave, and oven heating, and complies with FDA 21 CFR 175.300 standards.
– Honeycomb structure materials:
30-50μm specifications are used for honeycomb core materials in aerospace, high-speed rail, and construction. Our customized foils for Middle Eastern clients achieve superior bonding with adhesives through special surface treatments, increasing the compressive strength of honeycomb panels by 25%.
– Electronics and heat dissipation:
20-40μm specifications are used for electrolytic capacitor casings and battery pouches. Our high-precision foils, with thickness tolerance controlled within ±2%, are supplied to South Korean electronics manufacturers, helping to increase the energy density of their products by 8%. Annual exports exceed 800 tons of Haomei Aluminum.
– Construction and decoration sector:
80-150μm foil is used for sound barriers and composite panels. Our environmentally friendly 3003 H24 aluminium foil, certified by the EU REACH, has been successfully applied in noise reduction projects on German highways, reducing noise pollution emissions by over 30% annually.
As a manufacturer specializing in aluminum foil exports, we have established a full-process quality traceability system. From aluminum ingot procurement to finished product delivery, 12 inspection processes ensure that every roll of product meets customer requirements. For export needs, we provide customized packaging (moisture-proof film + fumigated wooden pallets), sea/air freight logistics solutions, and customs clearance support under HS code 7607119000, shortening the delivery cycle to 15-25 days.
Customized3003 H24 aluminum foil, with its balanced performance, stable processing, and wide range of applications, has become the preferred material for many industries.
