Silver Brazing
is a precision joining process offered at Subbaiah Enterprises, widely used in the fabrication of high-strength, leak-proof, and corrosion-resistant joints. This technique is especially suitable for joining dissimilar metals or components that cannot tolerate the high temperatures of welding.
What is Silver Brazing?
Silver brazing involves the use of a silver-based filler metal, which has a lower melting point than the base materials being joined. The filler metal is melted and distributed by capillary action between closely-fitted metal surfaces, forming a strong metallurgical bond without melting the base components.
- Typical brazing temperatures: 600°C to 850°C
- Common filler alloys: Silver-copper-zinc, Silver-copper-phosphorus, Silver-nickel
- Atmospheres used: Open flame, flux-assisted, or inert environments
Advantages of Silver Brazing
- Joins Dissimilar Metals: Effective on copper, brass, steel, stainless steel, and carbide.
- No Distortion or Warping: Base metals retain their mechanical and dimensional integrity.
- Strong, Durable Joints: High tensile and shear strength with excellent fatigue resistance.
- Leak-Proof Sealing: Ideal for pressure-tight and fluid-handling applications.
- Precision and Clean Finish: Minimal post-process machining or cleaning required.
