4045 Aluminum Alloy Powder · TIJO-4045
Aluminum-silicon brazing alloy -300 mesh / -150 mesh
Process Advantages
Low-melting eutectic system
Al–Si eutectic composition, with a moderate melting point and a favorable brazing temperature range, results in minimal thermal impact on the base material.
Excellent liquidity
The powder exhibits a well‑balanced particle size distribution, excellent spreading properties upon melting, strong gap‑filling capability, and produces brazed joints that are dense and reliable.
Specialized aluminum brazing filler metal
Standard brazing filler metals for aluminum and aluminum alloys exhibit excellent wettability with the base material, resulting in high joint strength and outstanding corrosion resistance.
Flexibly customizable granularity
We offer standard particle size specifications such as -300 mesh and -150 mesh, and also provide customized solutions tailored to customers’ specific process parameters.
