BRAZE STOP is a stop-off compound applied to fixtures, jigs, trays, and tooling to prevent brazing alloy from bonding to them during furnace brazing. It creates a barrier that releases cleanly after the braze cycle, protecting equipment and ensuring parts can be removed without damage.

• Applied to conveyor trays and furnace fixtures to prevent alloy pick-up
• Protects locating pins, jig components, and support tooling
• Prevents inadvertent braze bonding between stacked or touching components
• Compatible with controlled atmosphere (CAB) furnace environments
• Cleans off after braze cycle — no mechanical removal required

Alumatec™ BL 225 is a liquid surface surfactant formulated to reduce surface tension on aluminum components prior to flux or paste application. By improving the wettability of the aluminum surface, it enables more even and consistent flux coverage — particularly useful on complex geometries where flux may bead or run off.

• Reduces surface tension for improved flux spreading and adhesion
• Compatible with Alumakote™ spray flux systems
• Improves flux distribution on fins, tubes, and formed aluminum parts
• Suitable for use in pre-treatment wash stages before fluxing
• Supports consistent flux loading across high-volume production runs

Alumatec™ X79 is a purpose-formulated flux remover for post-braze cleaning of corrosive flux residues from aluminum assemblies. After flame brazing with chloride-based flux systems such as Alumaflo, residual flux must be removed to prevent ongoing corrosion. X79 neutralises and dissolves flux residues without damaging the base aluminum or brazed joints.

• Removes corrosive chloride-based flux residues after flame brazing
• Compatible with Alumaflo corrosive flux products
• Formulated to be safe on aluminum alloys — no alloy attack
• Suitable for immersion bath, spray rinse, or brush application
• Available in bulk volumes for industrial wash line integration

Note: Post-braze cleaning is required when using Alumaflo corrosive flux. Non-corrosive CAB processes using Alumatec™ or Alumakote™ do not require flux removal.

The Braze Flux Paste Dispenser is purpose-designed equipment for the controlled, precise application of flux paste — including Alumasil™ Braze Paste and Alumatec™ B Tube Flux Paste — to aluminum heat exchanger components. Consistent bead size and placement are critical to joint quality; this dispenser system is engineered to deliver repeatable results in production environments.

• Precision dispensing for consistent paste volume per joint
• Compatible with Alumasil™ Braze Paste and Alumatec™ B Tube Flux
• Reduces over-application and material waste
• Suitable for both manual and semi-automated production
• Full product flyer and specifications available in PDF format
