As a technical engineer at Haomei Aluminum responsible for surface treatment processes, I have overseen the production of over 1000 batches of silver brushed aluminum sheets. I deeply understand that the core value of this product lies in its precision craftsmanship, stable performance, and global adaptability.
Our silver brushed aluminum sheets utilize four mainstream alloy series: 1100/3003/5052/6061, covering a full range of specifications from ultra-thin 0.2mm to thick 6.0mm. Standard widths are 1220mm/1524mm, with customization up to 2000mm for ultra-wide sheets, and lengths up to 6000mm. Tempers include H14/H16/H18/H24/H32/H34, meeting diverse strength requirements from decorative to structural applications.
Surface textures of brushed silver aluminum sheet are available in #180-#800 grit sandpaper:
#180-#320 is used for architectural decoration, offering a rugged and three-dimensional texture;
#400-#600 is suitable for appliance panels, balancing texture and fingerprint resistance;
#800 is an ultra-fine brushed finish, exclusively for high-end electronic devices and automotive interiors.
All products comply with ASTM B209, EN 573-3, and GB/T 3880 standards, and are available with international certifications such as AAMA2605, CE, and RoHS. For the North American market, weather-resistant products conforming to AAMA2605-20 can be customized.
We employ an industry-leading three-stage process: degreasing, precision brushing, and passivation sealing, with digital monitoring at each step:
1. Degreasing and purification:
Alkaline electrolytic degreasing and ultrasonic cleaning remove rolling oil and oxide layers from the aluminum coil surface, ensuring uniform brushing performance—a crucial step in resolving “texture color differences.”
2. Precision wire drawing:
Our independently developed dual-belt synchronous wire drawing machine achieves a linear speed controlled at 15-25 m/min and a pressure error ≤ ±0.5 N, resulting in a surface texture depth deviation of <0.01 mm per square meter and continuous production of 1000 meters without breakage. For export to North America, we have specifically optimized the “anti-warping wire drawing parameters” to address deformation issues in low-temperature environments.
3. Passivation and sealing:
Utilizing a chromium-free passivation process, a 2-5 μm conversion film is formed. Combined with silane sealing, it achieves 96 hours of salt spray resistance without white rust, far exceeding the industry standard of 72 hours. Products exported to the EU have additionally obtained CBAM carbon footprint certification, reducing carbon emissions per ton by 12%.
Four core advantages made brushed aluminum sheet a perfect material for construction and decoration industry.
1. Surface stability:
Through a collaborative “film-texture” design, the surface hardness reaches HV300+, improving scratch resistance by 40%, making it particularly suitable for frequently touched environments such as home appliances and automotive interiors.
2. Weather resistance:
Our customized salt spray resistant version for Middle Eastern clients passed a 168-hour salt spray test and showed no significant fading after 5 years of use in high-temperature and high-humidity environments such as Dubai and Qatar.
3. Processing efficiency:
Maintaining excellent bending performance after wire drawing, 3mm thick 3003 aluminum sheets can achieve an inner bend of R=3mm without cracking, adapting to clients’ continuous stamping production lines and increasing production efficiency by 30%.
4. Cost advantage:
Our independently developed abrasive belt regeneration technology reduces wire drawing material costs by 22%, and this cost advantage is passed on to clients through large-scale production. Our FOB Shanghai price is 5-8% lower than the industry average, while guaranteeing fast delivery within 15 days.
Applications of silver brushed aluminum sheets across all scenarios:
– Architectural decoration:
Landmark projects in North America use 3mm thick 3003 brushed aluminum sheets for facades and ceilings. The lightweight design reduces curtain wall load by 40% and increases installation efficiency by 50%.
– Home appliance manufacturing:
Brands like Haier and Midea use 0.8mm thick 5052 brushed aluminum sheet for refrigerator door panels and air conditioner casings, with an annual supply exceeding 500,000 square meters. The surface withstands 1000 wipes without leaving a mark in oil stain tests.
– Electronics & communications:
We supply Dell and HP with 0.3mm ultra-thin 1100 brushed aluminum sheets for laptop casings. Nanoscale texture control ensures a reflectivity error of ≤±3%, meeting high-end electronic aesthetic standards.
– Transportation:
We supply Tesla with 6061 brushed aluminum sheets for charging station casings, achieving a tensile strength of 260MPa, meeting the structural requirements for outdoor installations.
Our silver brushed aluminum sheets utilize a digital traceability system, from alloy ratios to surface treatment. Each batch of products allows for the tracking of 128 process parameters and 32 test data points. As a manufacturer with high volume exported, we are familiar with the technical barriers in major global markets and can provide customized solutions for our clients, including special texture development, weather resistance enhancement, and packaging optimization.
