In every electrical system — from everyday appliances to industrial machinery — the invisible heroes that ensure reliable power transfer are often the Contact Rivets.
These tiny yet powerful components are the silent conductors of electricity, ensuring that every connection remains stable, efficient, and durable.
At Surinder Rivets Industries, a renowned Manufacturer and Supplier of Contact Rivets, innovation meets metallurgy. The company’s precision-engineered rivets are crafted to perform under the most demanding industrial conditions — from high-voltage circuits to intricate electronic devices — making them indispensable in modern engineering.
Contact rivets are metallic fasteners specifically designed to conduct current between two electrical parts while maintaining mechanical integrity.
Unlike regular rivets, contact rivets combine mechanical fastening and electrical conduction, forming a permanent bond with low resistance and high durability.
The secret lies in their material composition — metals like silver, copper, brass, and tungsten are commonly used for their excellent electrical and thermal properties. In modern designs, bimetallic combinations such as Silver-Cadmium Oxide or Silver-Nickel are employed for enhanced arc resistance and longevity.
These rivets are crucial in:
Every single rivet produced at Surinder Rivets Industries is precision-machined to meet exacting standards of conductivity, contact pressure, and dimensional tolerance.
The performance of contact rivets depends heavily on metallurgical factors. Metals with high conductivity, oxidation resistance, and wear endurance are preferred.
Some of the most widely used alloys include:
At Surinder Rivets Industries, every metal is selected after rigorous testing for purity, hardness, and microstructure consistency. Advanced metallurgical techniques such as sintering, forging, and bonding are employed to produce contact rivets with unmatched homogeneity.
The process of manufacturing contact rivets involves high-precision stages that define the rivet’s quality and lifespan.
Step 1: Raw Material Selection and Preparation
Only certified grades of metals are sourced to ensure consistent conductivity and resistance.
Step 2: Wire Drawing and Cutting
The metal is drawn into fine wires, maintaining uniform cross-sections, which are then cut into exact lengths.
Step 3: Head Forming
Specialized cold-forming or hot-pressing machines create the rivet head, ensuring proper shape and strength for consistent contact pressure.
Step 4: Surface Finishing and Cleaning
Each rivet undergoes precision polishing and cleaning to remove oxides and improve surface conductivity.
Step 5: Quality Inspection and Testing
Rivets are subjected to resistance, hardness, and dimensional tests, ensuring compliance with international standards such as IEC and ASTM.
Step 6: Packaging and Delivery
Surinder Rivets Industries ensures moisture-free, secure packaging to preserve integrity during transportation and storage.
