Corrosion resistance, conductivity and mechanical strength are essential considerations in bond design to ensure an earthing system remains operative for many years.
All Furse earth clamps have high strength copper or aluminium alloy bodies and screws e.g. aluminium bronze, phosphor bronze etc. – commercial brass is not used.
