February 03, 2026 – PRESSADVANTAGE –
Parfuse Corporation, a metal fabrication and aluminum processing company based in Westbury, New York, has announced the availability of salt residue testing for aluminum assemblies as part of its secondary operations portfolio. The testing service, which focuses on detecting and verifying chloride residue removal following aluminum brazing processes, is now being introduced at additional locations served by the company, including Garden City, Hempstead, and Mineola, New York. The announcement reflects a recent operational development aimed at supporting manufacturers that require documented surface cleanliness for aluminum components used in regulated and performance-sensitive environments.
Salt residue testing plays a critical role in aluminum assembly production, particularly for components brazed with chloride-based fluxes. Residual salts left on aluminum surfaces after brazing can contribute to corrosion, reduced service life, and long-term reliability concerns if not properly identified and removed. By formalizing and expanding this testing capability, Parfuse Corporation is responding to increasing industry requirements for verification, traceability, and quality control during post-brazing inspection.
The newly announced service applies specifically to aluminum assemblies and is aligned with Parfuse Corporation’s long-standing focus on aluminum-only fabrication and joining processes. Testing is performed after the flux removal and cleaning stages to confirm that chloride residues have been effectively eliminated before final assembly, finishing, or shipment. This step is particularly relevant for aluminum parts intended for aerospace, medical equipment, electronics, automotive, and military applications, where material integrity and surface condition are closely scrutinized.
Salt residue testing at Parfuse Corporation is conducted using a controlled silver nitrate test method. Following brazing, aluminum assemblies are rinsed with deionized or distilled water to flush component surfaces and internal passages. An aqueous silver nitrate solution is then applied to detect chloride ions. If residue is detected, additional cleaning is performed, and the test is repeated until no reaction is observed. This process allows technicians to verify that assemblies meet cleanliness requirements before progressing to downstream operations.
The formal expansion and communication of salt residue testing reflect changing customer expectations and compliance requirements. Many aluminum assemblies are produced for applications where surface condition is critical alongside structural performance. Salt residue testing provides an objective method for verifying effective post-brazing cleaning and supports consistent quality documentation and inspection practices across all serviced locations.
The value of salt residue testing extends beyond corrosion prevention. In complex aluminum assemblies that include enclosed channels, tight joints, or thin-wall components, undetected flux residue can interfere with later finishing steps such as anodizing, coating, or chem film application. By verifying cleanliness earlier in the production cycle, manufacturers can reduce the risk of rework, delays, or nonconformance during final inspection.
Parfuse Corporation’s expansion of this service is also tied to its integrated production model. The company performs aluminum dip brazing, heat treating, etching and cleaning, aluminum parts finishing, and secondary operations within the same facility. This allows salt residue testing to be incorporated directly into established workflows rather than treated as a separate or outsourced step. As a result, aluminum assemblies can move through fabrication, joining, cleaning, testing, and finishing under a single quality system.
Industry standards and customer specifications increasingly call for documented evidence of post-braze cleanliness, particularly for assemblies exposed to moisture, thermal cycling, or long service intervals. Salt residue testing supports these requirements by providing a repeatable and observable verification method. While the process itself is well established, its formal inclusion as a defined service reflects a broader trend toward greater transparency and process validation in aluminum manufacturing.
The availability of salt residue testing across Parfuse Corporation’s service areas is expected to benefit regional manufacturers that rely on aluminum brazed assemblies but lack in-house testing capabilities. By offering the service locally, Parfuse Corporation helps reduce the need for additional handling or transportation to third-party laboratories, thereby reducing scheduling challenges and logistical complexity.
In addition to serving Westbury, the company’s primary location, the service is now being communicated to customers in Garden City, Hempstead, and Mineola. These areas include a mix of industrial, commercial, and light manufacturing operations that utilize aluminum components in both prototype and production environments. The expanded availability ensures that customers across Nassau County can access consistent testing procedures regardless of project location.
Parfuse Corporation has operated for more than five decades and is known for its specialization in aluminum dip brazing and related secondary processes. Its focus on aluminum assemblies has allowed the company to develop process controls and inspection methods tailored to the material’s specific properties. Salt residue testing builds on this foundation by addressing one of the most common post-brazing concerns associated with aluminum and chloride-based flux systems.
While the service is technical in nature, its implications are practical. Assemblies that pass salt residue testing are better positioned to perform reliably over time, particularly in environments where corrosion resistance is critical. The testing also provides manufacturers with added confidence during audits, customer reviews, and regulatory assessments.
As production requirements continue to evolve, Parfuse Corporation expects verification services, such as salt-residue testing, to play an increasingly prominent role in aluminum assembly workflows. By introducing this capability across its service areas, the company is aligning its operations with current industry expectations for documented quality assurance.
Parfuse Corporation is located at 65 Kinkel Street in Westbury, New York, and serves customers throughout Nassau County. The company specializes exclusively in aluminum fabrication, brazing, and finishing services. Inquiries regarding salt residue testing for aluminum assemblies and related secondary operations are accepted via email to support engineering review and technical coordination before production.
