NAVSEA Performed TZ Corrosion Testing
GLENAIR
• Brutal test plan. Sequentially tested. • Fewer groups than MIL-DTL-38999 with as many tests, some far more difficult • Outperformed Zinc-Nickel and others • Retained functionality including conductivity after all tests • Included Electromagnetic Effects testing per MIL-PRF-28876 • Will be the ONLY approved conductive finish for MIL-PRF-28876 receptacles. • NAVSEA sent letters of recommendation to SAE and DLA for inclusion into all shipboard electrical connector specs
• Tested and Approved by NAVSEA • AIR5919 Tested/Passed (GT-17-120) • Tested/Passed VG95234 Glenair Italia (RDP 382-18) • Replaced Ni-PTFE in MIL-DTL-28840.
Tin-Zinc: Gold Standard of the Future!
• AS85049 draft proposed class V • Most compatible with Cadmium • More conductive than Zinc-Nickel
Tin-Zinc vs. Cadmium • RoHS Compliant • Same corrosion resistance, conductivity, operating temperature, and solderability • Improved resistance to SO2 and mixed gasses.
Tin-Zinc vs. Zinc Nickel • Contains less Zinc, produces less Zinc Oxide and Carbonate corrosion by product. Functionality remains after corrosion. • Higher Electrical conductivity • Better interoperability with Cadmium plated parts
Tin-Zinc vs. Ni-PTFE • Sacrificial plating protects base material if surface is damaged • Better Corrosion protection • Better interoperability with Cadmium plated parts
Cadmium and Cadmium-Alternative Finishes go Head-to-Head
