WELDING ALLOYS, BRAZING ALLOYS & PRE-SINTERED PERFORMS (PSPs)
We offer Aimtek’s complete line of aerospace grade welding alloys, brazing alloys and pre-sintered performs (PSPs).
Precision Spooled Wire
Aimtek precision level layer wound welding and brazing alloys are available in a variety of spool and reel sizes ranging from 12” in diameter down to 4” in diameter. Custom spool and reel sizes are also available. Spool materials include plastic, fibreboard, and metal.
Cut Length Wire
Aimtek’s precision wire straightening and cutting capabilities enable wires to be cut to any length and tolerance.
Meeting the strictest aerospace and industry standards for surface condition and cleanliness, wires are cleaned using ultrasonic, solvent, centreless grinding and other mechanical-based methods.
Braze Foil and Tape
Braze foils are manufactured using precision rolling and melt-spun processes. Custom slitting can produce widths as low as 0.020” to widths greater than 12”. Tapes are manufactured using the highest quality of binders and adhesives, which are cleanly burned in the brazing process.Braze Rings and Preforms
Brazing rings and preforms are manufactured according to customers’ drawing requirements and can accommodate endless part configurations and brazing methods, improving productivity and eliminating waste. Manufacturing processes include turning, stamping, laser, waterjet, and PSPs.Flux and Brazing Aids
Aimtek stocks all major brands of flux, stop-off compounds, and chemical aids. Flux meets popular industry specifications such as AMS3410, AMS3411, AMS3417, PWA809, AWS A5.31, and O-F-499D. Stop-off compounds are formulated for all types of brazing methods and base materials.Test Coupons
Aimtek supplies test coupons in many forms for welding and thermal spray process qualification. Test pieces are manufactured to tight tolerances from bar, sheet, and plate using precision machining methods.Custom Labelling, Identification and Packaging
Aimtek’s custom identification and packaging solutions enable customers to ensure product integrity.
Welding and brazing alloys can be individually packaged and identified by many industry-approved methods including flag tagging, colour coding, bar coding, and RFID. Flag tag labels can be custom printed to include information such as lot and purchase order numbers. Colour coding is performed using high quality painting methods and materials.
The finished product is alloy-type tested using Acromag and other approved alloy verification methods.
Packaging solutions include heavy thickness polyethylene, vapor-barrier materials and high-strength corrugated boxes. Argon purge and vacuum packaging is recommended for Titanium, high-purity, and corrosion-prone materials. All packaging and labelling are carried out according to customer specifications.Alloy Verification
All welding rods are fully verified using thermoelectric and/or XRF (X-ray fluorescence) Testing methods.

Our engineers have many years of experience in the metallurgical and thermal processing fields. Aimtek can assist our customers in developing brazing parameters, furnace conditions, surface preparation, and welding parameters. Consulting services are also available.
Many brazing alloys are available in powder and paste form. All powders are inert gas atomised and screened to various particle sizes ranging from fine to coarse.
Aimtek’s proprietary paste formulations and mixing processes provide smooth-flowing products via a variety of cartridge and syringe dispensing equipment. Binders are chosen based on the brazing process and leaves no trace of residue on the part.
