3. Core Product Advantages

Stable Electrical Performance

• AA3105 aluminum coil retains high and uniform electrical conductivity, with low resistivity and stable conductive performance. It will not generate electromagnetic interference or conductive failure during long-term operation of electronic equipment, fully meeting the power transmission and electromagnetic shielding requirements of precision electrical equipment.

Excellent Formability and Processability

• Compared with 1000 series pure aluminum and conventional 3003 alloy, it has higher structural strength while maintaining excellent bending, stamping and rolling performance. It supports fine deep drawing and precise shaping, no cracking or deformation during high-precision processing, suitable for mass production of electronic precision parts.

Superior Corrosion Resistance

• The optimized manganese-magnesium alloy formula effectively improves atmospheric corrosion resistance and oxidation resistance. It can resist moisture, weak acid and alkali erosion in complex electrical working environments, avoid surface oxidation and rust, and extend the service life of electrical components.

Excellent Coating and Insulation Compatibility

• The product has uniform surface texture and strong coating adhesion, which can perfectly match insulating paint, anti-corrosion coating and electromagnetic shielding coating. The coated surface is flat and firm, not easy to peel off, ensuring the insulation safety and shielding stability of electrical equipment.

High Dimensional Precision & Uniform Texture

• Adopting advanced continuous rolling process, the coil thickness and width tolerance are strictly controlled, with uniform internal metal texture, no internal stress. It effectively avoids dimensional deviation and component failure caused by material deformation in electronic assembly.

Lightweight & Energy-Saving

• Low density and light weight can effectively reduce the overall weight of electronic and electrical equipment, reduce equipment energy consumption, and improve product portability and installation efficiency.
