Specialized Aluminum Brazing Services for Demanding Projects
Parfuse Corporation provides aluminum brazing services that allow multiple joints or parts of different thicknesses to be joined with strength and precision. This method is a cost-effective option for assembling complex parts. With large brazing furnaces, we support the production of medical equipment, electronic components such as fuses and motors, aerospace structures like fuel lines, and military assemblies.
For more than five decades, Parfuse has delivered high-quality brazements for aerospace, instrumentation, medical, avionics, military, electronics, and automotive industries.
Our Primary Services
Aluminum Dip Brazing
Aluminum dip brazing is very different from conventional welding and riveting. Instead of using lots of heat to form a joint, a filler metal is introduced between the joint interfaces.
The pieces to be assembled are brazed by flowing filler metal between the joint interfaces. The temperature at the time of introduction is usually below the melting point of the base metal. When the filler metal cools and returns to its solid state, it creates a firm metallic bond and connects the joint area. Take a look at the brazeable aluminum alloys:
| Table A | Economical | Strength | Energy Used | Control | Flexibility |

Aluminum Heat Treating Services
Heat treating is a critical step in the aluminum manufacturing process to achieve the required end-use properties.
Heat treatment increases the strength and hardness of aluminum alloys. The process requires temperature uniformity, precise control of time-temperature profile, and compliance with industry specifications.
Secondary Services
Aluminum Finishing and Secondary Operations
Parfuse Corporation provides a full range of aluminum finishing and secondary operations to enhance both the appearance and performance of assemblies. Components can be polished, painted, anodized, or treated with chem film coatings to ensure corrosion resistance, durability, and long-lasting protection. These finishing processes deliver assemblies that meet aerospace, medical, automotive, and electronics industry standards for reliability and precision.
Salt Residue Testing for Aluminum Assemblies
Using the silver nitrate test, aluminum assemblies brazed using corrosive chloride-based flux are tested for flux and flux residues after flux removal.
The assembly is rinsed with deionized or distilled water until component areas are flushed. An aqueous solution of silver nitrate is then added. Assemblies are cleaned and tested until there’s no evidence of flux residue.
Aluminum Assembly Services
Our skilled technicians handle complex aluminum assemblies with precision and consistency.
From sheet metal components to electronic chassis and advanced heat exchangers, Parfuse Corporation has built a strong reputation for producing reliable, high-performance parts. Assembly is an integral part of the aluminum dip brazing process, ensuring every component is aligned with strict design specifications and quality standards.
