Flux Characteristics and Transfer Systems in Electrostatic Application – Part 5

  Flux Powder Adhesion: Dust formation and flux fall off are of general interest to the brazing industry. Regardless of the application method, dust generation (particularly airborne fines) must be avoided or kept to a minimum. If dust formation cannot be prevented, local exhaust ventilation and meticulous housekeeping are recommended. The inhalation of flux dust […]

Flux Characteristics and Transfer Systems in Electrostatic Application – Part 4

  Experiments for Flux Powder Fluidization: To illustrate the relationship between flux properties and fluidization, a series of tests was carried out using Sample 1 and Sample 2. Attached are print-outs of the particle size distribution analysis (Sympatec Helios H0851; dry powder analysis with laser) of both materials. Table 1: Particle Size Distribution Sample 1 […]

Flux Characteristics and Transfer Systems in Electrostatic Application – Part 2

  The background of electrostatic flux application: When controlled atmosphere brazing with non-corrosive fluxes was introduced, the only realistic method for using the flux was wet application. This strategy was supported by the physical and chemical properties of flux powder. Non-corrosive fluxes for aluminum brazing consist of potassium fluoroaluminates (inorganic fluorides) with low water solubility. […]

Flux Characteristics and Transfer Systems in Electrostatic Application – Part 1

  Introduction: This article summarizes some experimental results of a project on electrostatic application of non-corrosive fluxes for aluminum brazing. The objective is to qualify and quantify flux powder properties and equipment parameters with positive effect for dry flux technology. For more than 30 years, controlled atmosphere brazing (CAB) [NOCOLOK ® Flux brazing] has been […]
