Nickel-free sealing advances slowly against corrosion test performance
European regulatory pressure on nickel compounds has pushed anodisers toward rare earth and silicate sealing chemistries, and roughly 16% of European lines have converted so far. Progress is slow because the alternatives seal adequately but have repeatedly underperformed hot nickel sealing under salt spray corrosion testing, which architectural specifications treat as a pass or fail criterion rather than a comparative measure. Commercially this gives producers a longer runway than the regulatory direction suggests, though the direction itself has never reversed and conversion continues line by line. Equipment replacement cycles set the pace more than policy does.
