WE ARE RECYCLERS OF USED CARBON WIND TURBINE SLIP RING BRUSHES

If you regularly replace carbon brushes in doubly fed generators we are interested in your commutator & slip ring carbon-metal brushes in any condition. Carbon-metal brushes are those used in shaft grounding & earthing, wind power electrical generation, severe duty, high altitude & corrosive atmosphere applications. We are interested in purchasing your old, worn, damaged new or unused brushes. Carbon-Metal brushes are those that have a metal such as Iron, Zinc, Lead, Silver, Copper & Tin impregnated or agglomerated into the carbon-graphite matrix. Vestas Wind Turbine Brushes and those marked 'ABB' always have the highest value. We are also always looking to purchase Vestas & Siemens brushes. Especially Brushes used in V80, V90, V100, V110 and V120 Wind Turbines. These brushes contain silver and copper and have valuable carbon all of which we recycle ourselves at our Ohio facility.

WE WILL BUY YOUR AIRCRAFT OR EMD SILVER BABBIT BEARINGS

We are also interested in your plain carbon-metal bearings or fluid film tin & silver babbit bearings. These are bearings that have valuable tin and silver attached to a parent metal ferrous bushing. In the past it has not been economical to remove the valuable babbit from the ferrous substrate. We utilize a newly developed green method to separate the valuable non-ferrous from the steel substrate. Typically these bearings are used in aerospace, heavy industy and power generation. Please contact us so we can make an offer on your materials.
