Products Description
This is a Monometal Contact Rivet designed specifically for high-end electrical connections. Its core feature lies in the "singleness" of the contact material; the entire contact surface is composed of a single material (such as pure silver or a specific silver alloy), eliminating heterogeneous interfaces with composite materials and ensuring exceptional electrical conduction stability. This product is commonly used in high-end relays, industrial control relays, and electric vehicle battery systems, serving as a key component for achieving highly reliable circuit switching.
Production Process and Flow
Alloy Material Selection
Based on order specifications, high-purity electrolytic silver (Ag≥99.99%) or specific silver alloys (such as AgNi10) are selected as the base material to ensure Fine Silver Contacts material uniformity and purity.
01
Precision Stamping
High-precision stamping equipment is used to stamp the material into contact rivets of specific shapes. This process requires extremely strict pressure control to prevent micro-cracks in the
Silver Alloy Point Contacts material.
02
Heat Treatment
The formed Solid Electrical Contacts undergo solution treatment or aging treatment (for specific alloys) to optimize their microstructure and improve hardness and wear resistance.
03
Surface Treatment
For non-pure silver materials, a surface oxide film is formed or a small amount of electroplating is applied as needed to further enhance resistance to sulfidation.

Frequently Asked Questions
Are Solid Ag contacts always superior to composite contacts?
They offer advantages in scenarios requiring high conductivity and stability, but are more expensive. The choice should be based on the project's requirements.
How to choose between Pure Ag and AgNi10?
Pure silver is preferable if low resistance and conductivity are emphasized; AgNi10 is preferable if arc resistance is emphasized.
Is it suitable for sulfur-containing environments?
The AgSnO₂ system exhibits stability in a 10ppm H₂S environment, with a resistance increase of <30%.
Is the Solid Electrical Contacts sample verification supported?
Small-batch sample testing is supported for lifespan and arc resistance testing
Product Certifications
This Silver Alloy Point Contacts has passed multiple international and domestic certifications, including ISO 9001 quality management system certification, IATF 16949 automotive industry quality management system certification, RoHS certification, and REACH certification. Fine Silver Contacts also complies with national industry standards such as GB/T 5583-2015 (Test Methods for Electrical Contact Materials) and GB/T 14048.1-2012 (Low-voltage switchgear and controlgear), and can be directly used in the production of high-end electrical equipment without additional certification adaptation. Furthermore, customized certification services can be provided according to customer needs, assisting customers in completing relevant certification tests to meet the specific certification requirements of their projects and ensure smooth project progress.
