What is a High Voltage DC Contactor Stamped Pure Iron Armature?
High Voltage DC Contactor Stamped Pure Iron Armature is designed for automotive relays and high voltage DC contactor systems where electromagnetic movement, electrical conductivity, and mechanical endurance must work together under vibration and temperature cycling conditions. The assembly integrates a stamped pure iron armature, beryllium copper (BeCu) spring blade, and silver-based contact rivet through precision riveting technology. The integrated structure eliminates secondary component alignment and provides stable contact positioning during repeated switching operations.
The Precision Relay Armature provides magnetic response for relay actuation, while the BeCu spring maintains elastic recovery force and conductive performance. The silver contact interface is engineered for repeated current switching applications, including automotive power distribution, vehicle control modules, and DC relay systems.
Manufacturing Process & Structural Reliability of Relay Armature
Cold-Heading Precision: We employ high-tonnage eccentric presses to achieve a precise metallurgical bond between the AgSnO2 contact tip and the base alloy of New Energy Vehicle Relay Armature. This prevents contact separation caused by thermal expansion mismatch for EV power switching parts.
Surface Passivation: All components of EV Relay Magnetic Armature undergo a proprietary chemical passivation process. This enhances surface corrosion resistance against automotive fluids and environmental humidity, exceeding 72-hour salt spray test standards for long-life automotive relay assemblies.
Power Relay Armature is engineered specifically for the harsh electrical environments of automotive relay and contactor systems. The low-resistance contact patch minimizes heat generation during peak current draw.
High-Voltage DC Switching
EV Relay Magnetic Armature is designed for 800V HVDC EV contactors where arc-suppression is vital. The AgSnO2 material composition limits material transfer during make-break operations, extending operational lifespan.
Automotive Control Relays
Soft Magnetic Armature for EV Relay has proven performance in automotive horn switches and power distribution units (PDUs). The high fatigue strength of the BeCu substrate ensures consistent contact pressure throughout the vehicle's service life.
