Advantages Of Honeywell Brazing flux
Honeywell 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)
Honeywell 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
Customer Benefits:
- Wider flux reactivity range
- Up to 20% extra time for improved cleaning and oxide removal
- Energy savings drive eco-balance and reduce cost
- Higher reactivity enables lower flux loading
- Robust brazing process
A more controlled and narrow particle size distribution
Honeywell 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
