DIN 50965 was a German industrial standard titled "Electroplated coatings on iron and steel – Zinc-iron alloys (ZF) and Zinc-nickel alloys (ZN)." Before the harmonization of European standards (EN), this document was the gold standard for specifying alloy-based zinc plating.
Unlike standard zinc plating (DIN 50960), DIN 50965 focused specifically on alloy coatings to provide superior corrosion resistance and better thermal stability than pure zinc.
Because DIN 50965 is withdrawn, free PDFs floating on websites often contain scanning errors missing crucial appendices (like adhesion test methods). Here is where to find accurate documents:
If your search for DIN 50965 PDF is because you have a specific substrate issue, consider these other German standards:
| If you need... | Standard to search for... | | :--- | :--- | | Zinc plating on iron/steel (Pure Zn) | DIN 50960 (withdrawn) → ISO 2081 | | Zinc on Copper/Brass | DIN 50966 (withdrawn) | | Mechanical plating (Peen plating) | DIN 50967 | | Cadmium plating (Aerospace) | DIN 50951 (Restricted/RoHS exempt) |
To understand the value of the old DIN 50965 PDF, you must understand the metallurgy:
| Feature | Pure Zinc (DIN 50960) | Zinc-Iron (ZF) | Zinc-Nickel (ZN) | | :--- | :--- | :--- | :--- | | Nickel Content | 0% | 0.5% - 1.5% | 12% - 15% | | Hardness | Low | Medium | High | | Corrosion (Salt Spray) | 72 - 120 hrs | 150 - 250 hrs | 500 - 1000+ hrs | | Hydrogen Embrittlement Risk | Moderate | Low | Very Low | | Typical Use | Indoor hardware | Brake calipers, Fuel lines | Under-hood, High heat |
The DIN 50965 PDF provided specific tables dictating which alloy to use based on the "Stressed Condition" of the part.

DIN 50965 is a German technical standard that provides specifications for electroplated tin coatings on iron (ferrous) and copper-based materials. Overview of DIN 50965
The standard defines the requirements for tin coatings used to provide corrosion protection, improve solderability, or reduce contact resistance in electrical and industrial components.
Current Status: The most recent version is DIN 50965:2020-04.
Previous Editions: It superseded the previous edition, DIN 50965:2000-05. Primary Scope:
Specifies minimum coating thicknesses for different service conditions. DIN 50965 was a German industrial standard titled
Provides guidance on the surface finish and heat treatment of the base metal (substrate). Covers coatings on iron, steel, copper, and copper alloys.
Exclusions: It generally does not cover semi-finished products or specific fasteners, which are often handled under standards like DIN EN ISO 4042. Key Technical Components
Ordering Information: The standard specifies exactly what information a purchaser must provide to the manufacturer to ensure the coating meets the required specification.
Heat Treatment: It includes requirements for heat-treating parts to prevent hydrogen embrittlement, especially for high-strength steel components.
Solderability: While it specifies tin coatings, testers often refer to related standards like DIN EN 60068-2-20 to verify the actual solderability of the finished coating. Comparison of 2000 vs. 2020 Editions
The 2000 edition introduced amendments to ordering information and removed specific "service condition numbers" that were found in the 1982 version. The 2020 update was primarily an editorial and technical revision to align with modern European standards. Where to Access the PDF
