What are Gold Plated Bimetal Contacts?
Engineered for demanding micro-load switching and signal transmission applications, these components serve as critical switching interfaces inside telecommunication relays, smart meter latching mechanisms, and sensitive auxiliary switches. Fabricated using advanced cold-heading composite technology paired with precision electroplating, these Gold Plated Bimetal Contacts eliminate surface oxide films and guarantee stable signal integrity across millions of mechanical cycles. As an established direct factory supplier in China, we deliver custom-engineered wholesale solutions tailored to rigorous electrical and mechanical specifications.

Production & Quality Control of gold plating on electrical contacts
Dust‑Free Production Workshop
Manufacturing occurs in a climate‑controlled, dust‑free stamping and heading environment to eliminate airborne particulate contamination between core bonding stages.
Advanced Electroplating Equipment
Automated barrel and rack gold‑plating lines utilize strict chemical bath monitoring to ensure uniform coating thickness, crystal structure density, and zero pinhole defects.
Strict In‑Process Quality Inspection
Every production batch undergoes automated optical sorting and X‑ray fluorescence (XRF) coating thickness analysis to guarantee compliance with exact engineering blueprints.
Frequently Asked Questions about gold plated contact
What is the typical thickness of the gold plating on these Bimetal Contacts with Au Plated?
+
-
The standard gold flash thickness ranges from 1.0 to 3.0 micrometers, deposited over a nickel underplate diffusion barrier to prevent base metal migration.
Why use a gold flash layer on silver‑nickel or silver‑cadmium oxide contact rivets?
+
-
Gold flash prevents surface oxidation and sulfide film formation during storage and low‑frequency operation, ensuring low initial contact resistance in dry circuits.
How is the bonding strength between the precious tip and substrate tested?
+
-
Bonding integrity is verified via destructive shear strength tests, requiring minimum force thresholds exceeding 250 MPa to ensure separation resistance under great mechanical shock.
Can these Gold Plated Contacts withstand high‑frequency mechanical switching operations?
+
-
Yes, the robust cold‑headed bimetal structure and uniform gold coating endure millions of actuation cycles without micro‑welding or structural delamination.
What lead time can we expect for custom tooling and prototype sampling?
+
-
Custom tool design and initial sample fabrication typically require 10 to 15 business days, followed by express air shipping for engineering evaluation.
