As a professional manufacturer with many years of experience in the aluminum sheet export sector, Haomei Aluminum leverages its complete aluminum processing industry chain and stringent quality control to offer global customers 3003 and 5005 series gold anodized aluminum sheets. These aluminum sheets combine high-end decorative appeal with excellent practicality, making them suitable for various export scenarios across multiple industries.
Regarding product specifications, we strictly adhere to international standards (RoHS, ISO 45001) and can customize products to meet the needs of different global markets. The base materials are selected from two mainstream alloys, 3003 and 5005, with a thickness range of 0.1-4.0mm, a width of 50-1520mm, and the length can be flexibly cut according to customer orders. The anodized film thickness is divided into AA5-AA20 grades, with AA5-AA10 grades suitable for indoor applications and AA15-AA20 grades suitable for outdoor and moderately corrosive environments. Gold colors can be customized, including light gold, road gold, bright gold, and matte gold. The surface can be processed into various textures such as brushed, frosted, and mirror finishes, fully meeting the customization needs of customers in different countries.
In terms of core characteristics, the two alloys of gold anodized aluminum sheet each have their own focus while also sharing commonalities.
– Alloy 3003 is primarily composed of aluminum (≥98%), supplemented with manganese. Belonging to the Al-Mn series of rust-resistant aluminum, its corrosion resistance is close to that of industrial pure aluminum. It has an elongation of approximately 10%, excellent plasticity, and can be easily bent into shape.
– Alloy 5005 is primarily alloyed with magnesium, with a slightly higher aluminum purity (97.0%-99.5%). Its tensile strength is superior to alloy 3003, and it exhibits stronger weather resistance, making it suitable for long-term outdoor use. After gold anodizing, both alloys possess uniform color and are resistant to fading. The oxide film has high hardness and scratch resistance, achieving over 300 hours of salt spray testing, far exceeding ordinary aluminum plates. Furthermore, they offer significant lightweight advantages, with a density only one-third that of stainless steel.
In terms of production technology, we rely on our own CNAS-accredited laboratory and advanced production lines, employing a room-temperature golden yellow dyeing process with rigorous and controllable procedures:
– First, the substrate undergoes degreasing, alkaline etching, and neutralization pretreatment to remove surface impurities and mechanical marks.
– Then, anodizing is performed in a sulfuric acid electrolyte at 18-22℃ to generate a dense oxide film of 5-25μm; subsequently, room-temperature dyeing with organometallic dyes ensures uniform gold penetration into the film pores.
– Finally, high-temperature sealing treatment further densifies the oxide film and extends its service life. The entire process is free of harmful emissions, meeting global environmental standards, and allows for mass production, with strict control over color differences to ensure consistent quality for every batch of exported products.
Our core export advantages are prominent, aligning with global procurement needs. We possess complete export qualifications, and our products conform to international standards such as ASTM B580. We can provide customs compliance documents and quality inspection reports. Leveraging years of export experience, we can flexibly adapt to the size and standard requirements of different countries, ensuring stable delivery times. Compared to similar products, our gold anodized aluminum sheet products offer more precise color difference control, stronger oxide film adhesion, and outstanding cost-effectiveness. We also provide comprehensive after-sales and technical support to solve various problems customers encounter during export and use.
Our gold anodized aluminum sheet products have a wide range of applications, covering multiple industries globally.
In the indoor sector, they can be used for hotel lobbies, office building ceilings, shopping mall column cladding, and high-end club decoration.
Outdoors, they can be used for mid-rise building curtain walls, decorative moldings, and outdoor signage. They are also suitable for electronic appliance housings, automotive interiors, and medical device decoration.
Currently, we export to many countries and regions worldwide, gaining widespread recognition from overseas customers for our superior quality.
Haomei Aluminum prioritizes export quality. Our 3003 and 5005 gold anodized aluminum sheets combine decorative and practical features, can be customized to your needs, and are fully compliant throughout the process, making us your preferred partner for overseas procurement.
