Hello all.
Could anyone suggest a list of magnetorheological fluids makers, possibly european. Thanks

Depending on useage, you have different sources. You can make some at home, mix powdered iron with a thick oil.

For optics finishing some slightly abrasive fluids are available.

Or GM (Cadillac) has this in shock absorbers now, maybe can buy refil at parts store?

Sorry, someone corrects me, Lord Corporation makes the Cadillac shocks. Contact them as fluid is proprietary patent.

Lord Corp. production in 2004 was several hundred tons, ~600USD per Litre for small batch, ~60-180USD per Litre for big quantity.

Delphi makes the MagneRide shocks for GM using MR fluid from Lord.
