Certified Surplus Metals Buys Electrical Carbon Brushes from Turbines

 

We are 100% HIPAA Law Compliant!        

We are interested in purchasing your worn or old carbon metal slip ring brushes in any condition. 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. Wind Turbine brushes contain graphite, nickel, copper, silver, tungsten, tin lead, zinc and iron. We process brushes to their fundamental elements.

 

Metal graphite carbon brushes for electrical motors are often made from natural graphite and fine metal powders. Copper is the most common, but silver, tin and lead are sometimes used. Metal graphite brushes are ideal for many applications due to low resistivity. Metal graphite brushes are used on commutators of plating generators that have low voltage and high brush current densities. They operate on rings of wound rotor induction motors where high brush current densities are also found. Metal graphite brushes are used with grounding brushes because of their low contact drop.

 

We pay cash for your carbon metal slip ring brushes. Vestas, ABB, and Siemens-Gamesa have the highest value.

 

How to determine if your Carbon Brushes have Recycle Value:

  • Brushes with metal content are usually 5-10 times more expensive than standard graphite brushes.

  • Brushes that have metal value are usually in signal transfer, weather exposed, corrosive areas or in low voltage, voltage drop situations.

  • Brushes that have metal content have a lighter color than a plain carbon brush.

  • Brushes with metal content will always be heavier than plain carbon brushes.
