SILVER SOLDER 20% 2.4MM FLUX COATED

Silver Solder 20% – 2.4mm Flux Coated Brazing Rod

Silver Solder 20% 2.4mm Flux Coated is a high-quality, low-temperature brazing alloy designed for strong, clean, and reliable joints across a wide range of metals. With a 20% silver content, this flux-coated brazing rod delivers excellent capillary action, smooth flow characteristics, and superior joint strength—making it ideal for both professional trades and precision repair work.

The integrated flux coating simplifies the brazing process by eliminating the need for separate flux application. It actively cleans the joint area during heating, promotes wetting, and ensures consistent alloy flow for clean, defect-free brazed joints.

Key Features & Benefits

• 20% Silver Content – Provides strong, ductile joints with excellent corrosion resistance

• Flux Coated – Built-in flux cleans and protects the joint during brazing

• 2.4mm Diameter – Ideal for controlled heat input and precise brazing work

• Excellent Capillary Action – Ensures deep penetration and uniform joint fill

• Low Melting Range – Reduces heat distortion on thin or sensitive materials

• Clean, Smooth Flow – Produces neat joints with minimal post-cleaning required

Suitable Applications

• Copper and copper alloys

• Brass and bronze components

• Mild steel and carbon steel

• HVAC and refrigeration piping

• Plumbing and general maintenance repairs

• Electrical connections and small mechanical assemblies

Why Choose 20% Silver Solder?

Compared to lower silver content alloys, 20% silver solder offers improved flow, stronger joints, and better resistance to vibration and thermal cycling. The flux coating further enhances productivity by reducing setup time and ensuring consistent brazing results—especially in field repairs or tight working conditions.
