Custom Brass Welded Components
Products Description
Custom Brass Welded Components are engineered electrical contact assemblies tailored for low-voltage electrical systems, consisting of a brass substrate (including machined parts, bolts, or terminals) and silver contacts permanently joined via precision welding. They leverage the thermal and electrical conductivity of brass alongside the low contact resistance and arc erosion resistance of silver contacts. These components can be fully customized to meet specific customer requirements for current rating, mounting dimensions, contact geometry, etc., and are suitable for relays, switches, sockets, connectors, and other electrical devices. Typical applications span industrial control, smart home systems, automotive electronics, and related fields.
Product Advantages
No Cold Soldering, No Spatter
Brass Relay Pin Welding utilizes a medium-frequency inverter DC welding power supply. The precise matching of current rise slope and pressure timing eliminates spatter and insufficient penetration common in traditional AC resistance welding.
High Silver Material Utilization
For brazing silver contacts to copper bars of similar thickness, we use pre-placed silver solder rings or silver paste, saving 12-18% of silver material compared to manual feeding.
Welding Complex Geometries
Even welding stepped machined bolts to curved brass sheets can achieve reliable connections using customized electrodes.
Combined Full Inspection and Sampling Inspection
Each batch of Brass Contact Welding undergoes peel force testing, resistance testing, and metallographic sampling inspection.
Product Technical Advantages
Precision Welding Process Control
A standardized welding parameter control system is employed. Welding current, pressure, and time parameters are optimized for different specifications of silver contacts and brass substrates to ensure consistent weld strength and electrical performance.
01
Product Technical Advantages
Brass Base Machining Precision: Precision welding for brass parts is achieved through precision turning and stamping processes, with dimensional tolerances controlled within industry standards. This ensures precise matching with the mounting holes and thread specifications of customer products, eliminating the need for secondary machining.
02
Silver Contact Selection and Adaptation
We can recommend suitable silver alloy contact materials based on customer requirements such as current rating, switching frequency, and operating environment, balancing electrical performance with cost control to avoid over- or under-performance of welded brass terminal assemblies.
03
Comprehensive Quality Control
Multiple inspection stages are implemented during production, including weld strength testing, contact resistance testing, full dimensional inspection, and salt spray testing, ensuring the quality stability and compliance of every batch of welded brass socket contacts.
04
Application Areas
Relays
As the core electrical contact component of relays, it is compatible with electromagnetic relays, solid-state relays, etc., to achieve circuit switching control.
Switches
Resistance Brazing Electrical Contacts can be applied to wall switches, push-button switches, micro switches, etc., serving as contact components to achieve circuit conduction and disconnection.
Connectors and Sockets
Low Voltage Electrical Contacts serve as contact terminals in sockets and connectors, enabling current transmission between electrical devices.
Automotive Electronics
Spot Welding Assemblies are compatible with automotive relays, light switches, control modules, and other components, meeting the high reliability requirements of automotive environments.
