  • Copper and Electricity Introduction

    The copper cable (on the left) is thinner than the aluminium one, because copper is a better conductor. Its cross sectional area is 300 mm 2 as opposed to 500 mm 2 for the aluminium. There are four groups of wires within the cable and the groups are insulated with cross-linked high-density polyethene (XLPE).

  • FAQ's – Coppercoat Antifoul

    As Coppercoat is a blend of pure copper and two-pack epoxy resin, the coating is both strong and water-proof. After application the coating can be burnished to give a very smooth racing finish, which (as the coating is non-absorbent) is the equivalent of dry-sailing a boat but with the advantage of anti-fouling protection allowing the boat to ...

  • Copper Corrosion - an overview

    Zaki Ahmad, in Principles of Corrosion Engineering and Corrosion Control, 2006. 2) Galvanic Corrosion The potential range of aluminum alloy lies between –0.6 and 0.8 V vs the saturated calomel electrode. If aluminum is connected to copper (corrosion potential = –0.1 V), a significant difference of potential (–0.5 V) would exist and aluminum, being anodic to copper, would corrode.
