AI-Powered supplier vetting

SummaryHENAN CHALCO ALUMINUM INDUSTRIAL CO., LTD is identified as both a trading company and manufacturer/factory in China, offering a broad aluminum product range. It reports substantial production capacity across precision plates, forgings, industrial profiles, and sublimation sheets, supported by 50 R&D engineers and 50 quality-control staff. The supplier provides extensive customization, ODM, OEM, CAD/SolidWorks, and 3D design services, but reports zero R&D patents and no private molds. Complaint handling has a clear procedure and records, while corrective/preventive-action and supplier-assessment procedures are undocumented. Overseas service infrastructure is limited, with no overseas showroom, agents, branches, or offline trade-show participation. Financial information is indicated for 2022–2024, but no substantive financial condition is provided. Certification holdings and customer case details are not evidenced.

Supplier typeThe supplier is explicitly classified as both a trading company and manufacturer/factory, with a limited-company ownership structure and a stated aluminum-product business scope. This indicates a combined manufacturing and trading model rather than a purely intermediary operation.

After-Sales capabilityThe supplier has a clear procedure and follow-up records for handling customer complaints, which supports a defined complaint-response capability. However, it has no overseas showroom, agents, branches, or offline trade-show participation, and its broader service-assessment procedure lacks written procedures or records, indicating limited documented service infrastructure.

R&D capabilityThe supplier reports new products within the past year, ODM services, SolidWorks and CAD capability, and 3D software design services. Counterbalancing evidence includes zero R&D patents, no private molds, and no available SDK, so innovation capability is demonstrated mainly through applied design and development services rather than patent or software-platform assets.

Production capacityReported annual capacities include 50,000 tons of precision aluminum plate, 45,000 tons of aluminum forgings, 40,000 tons of industrial aluminum profiles, and 35,000 tons of sublimation aluminum sheet. The supplier also reports 50 quality-control staff and identifies itself as a manufacturer/factory, providing explicit evidence of substantial production capability.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, together with ODM services and 3D CAD/SolidWorks design support. These capabilities directly support broad product customization and design adaptation.

Product Q&A

Q:What is the composition ratio of the bimetallic washer?

The standard composition is 80% aluminum and 20% copper, but this ratio can be customized according to your requirements.

Q:Can the dimensions be customized?

Yes, we can manufacture the washers in mm or inches based on your specifications, drawings, or provided samples.

Q:What are the main applications of this product?

It is used for connections between copper and aluminum conductors in air conditioners, refrigerators, water tubes, and oil cooler pipes to prevent corrosion.

Q:How does the washer prevent corrosion?

The bimetallic structure, obtained by explosion welding, molecularly links copper and aluminum surfaces, preventing the onset of galvanic corrosion caused by electrolytes like humidity.

Q:What are the mechanical strength requirements?

The tensile strength is more than 120 N/mm2, and the peeling strength is more than 12 N/mm.
