This composite armature assembly is a critical component for electromagnetic actuators in electric vehicle high-voltage DC switching systems, engineered to balance high electrical conductivity and magnetic performance. The part combines 99.9% pure C110 copper contact surfaces (for low-resistance current transfer) with DT4C electrical steel (for optimal magnetic permeability), joined via precision brazing to ensure structural integrity under dynamic loads.
Machined to tight standard tolerances of ±0.005mm using advanced CNC processes, the assembly features precision mounting pins and alignment features for reliable integration into automotive switch mechanisms. Optional surface treatments include silver plating (5-10μm) for enhanced conductivity and oxidation resistance, or tin plating (3-5μm) for corrosion protection in harsh underhood environments.
Compliant with IATF 16949:2016 and ISO 9001:2015 standards, this armature assembly supports rapid prototyping (3-5 days lead time) and volume production (2-3 weeks lead time) for new energy vehicle OEM applications, with full material traceability and PPAP-ready documentation.
