Brazing AND Soldering Alloys

Brazing and soldering alloys form a specialized category of metals engineered for joining other materials at temperatures significantly lower than those used for structural metals. Key representatives include tin, lead, bismuth, and their alloys, all valued for enabling strong, conductive, and reliable joints with minimal heat input. These alloys are crucial in applications such as electronics assembly, safety devices, and precision manufacturing where controlled joining is required.

BRAZING VS. SOLDERING ALLOYS

Characterization & Comparison

Characterization & Properties

While both brazing and soldering alloys serve as joining materials, they differ notably in their working temperatures, chemical composition, and application areas:

Brazing / Soldering alloys possess several distinct properties that make them essential in various industries. Key characteristics include:

Soldering Alloys

Typically melt below 450°C and are primarily tin-based, sometimes alloyed with lead, silver, or bismuth. They are used in electronics, electrical work, and plumbing, forming conductive but lower-strength joints ideal for delicate or heat-sensitive assemblies.

Brazing alloys

Have melting or flow points above 450°C yet remain below the melting temperature of the base metals. Common base elements include copper, silver, aluminum, and nickel. Brazing produces stronger joints suitable for structural, automotive, and aerospace applications, where greater strength and temperature resistance are required.

BRAZING AND SOLDERING ALLOYS

KEY PROPERTIES

Brazing and soldering alloys are essential in industry thanks to their:

01

Low Melting or Flow Temperature

Sufficiently low to protect sensitive components, but high enough for secure bonding.

02

Excellent Conductivity

Many alloys exhibit outstanding electrical and thermal conductivity—vital for electronic applications.

03

Castability and Wetting

Formulated for excellent wetting and bonding to base metals, crucial for strong, durable joints. Their optimized compositions also allow for efficient powder atomization.

ULTRASONIC ATOMIZATION

HIGH QUALITY METAL POWDERS

Production Process: How Brazing and Soldering Alloy Powders Are Made

Our powders are produced by transforming ingots or pellets into small, uniform particles tailored to joining technologies. Induction-based ultrasonic atomization is used:

01

Melting

The alloy is heated to its flow point and introduced onto a vibrating sonotrode.

02

Atomization

Ultrasonic vibrations disperse the molten metal into fine droplets.

03

Solidification

These droplets quickly solidify into spherical, uniform powders in an inert atmosphere.
