Brazing Flux Product Range & Grades

Aluminum brazing flux from the industry’s leading provider

IMPROVE ALUMINUM BRAZING EFFICIENCES

Jet Applied Brazing Flux (JABF) can accelerate manufacturing of EV, Wind, Turbine, Solar Panel, and EV Charging Station heat exchangers, while reducing waste, energy, and labor costs. Pinpoint accuracy enables up to 85% less flux consumption, prevents flux from entering coolant channels, and can eliminate the post-brazing wash process.

Advantages of Solstice Advanced Materials Brazing Flux

Solstice Potassium Fluoroaluminate flux (AL-2805) enables a more robust and efficient brazing process when compared to other fluxes and is characterized by a uniform amorphous and less abrasive morphology, and a high reactivity with aluminum oxide.

A lower flux melting point of 552 (± 3.0°C)

Solstice Potassium Fluoroaluminate flux (AL-2805) has a unique multi-constituent phase, with amorphous amounts, providing a melting point of 552 ± 3.0°C. This melting point is 25 °C lower than the eutectic melting point of an Al-Si filler metal.

Customer Benefits:

Low melting point
Reduced corrosion and abrasion
Controlled and narrow particle size distribution
Excellent free-flow and dispersion properties

Graph comparing the melting points of Solstice flux and competitive flux, showing that Solstice flux has a wider reactivity range.

Customer Benefits:

Wider flux reactivity range
Up to 20% extra time for improved cleaning and oxide removal
Energy savings drive eco-balance and reduces cost
Higher reactivity enables lower flux loading
Robust brazing process

A more controlled and narrow particle size distribution

Aluminum flux features controlled particle sizes to meet and exceed customer product and process requirements:

Narrow particle size distribution
High batch-to-batch consistency
Fast and complete dispersion in solution and slow settling
Leading to reduced corrosion and abrasion

Customer Benefits

Homogeneous distribution on parts and in paints / pastes
Easy and fast dispense due to uniformity of particles
No plugging of nozzles and pipes
No material loss on filters
No yield loss due to assembly defects
Uniform surface coverage
Robust application process
