   ZINC GALVANIC ANODES     
  PROPERTIES OF ZANODE

ZANODE is a cast type alloy anode with zinc having its purity of above 99.99% as its main component. ZANODE has the same components with MIL SPEC. A-18001-K, USA and has been widely accepted for about 30 years, especially by shipbuilders and owners all over the world, as the most ideal galvanic anodes for corrosion prevention.
The distinct properties of ZANODE are shown in the TABLE 1 and Graphic Display below.

  Specific gravity7.15  
  Potential (Ag/AgCl)(V)-1.05  
  Current efficiency (%)95  
  Effective current capacity (Ahr/kg)780  
  Potential difference (V)0.25  




   ALUMINUM GALVANIC ANODES     
  PROPERTIES OF ALUNODE

ALUNODE is a newly developed Al-Zn-In type alloy anode with high purity aluminium as main component and due to its large current capacity and light weight compared with other anodes, ALUNODE has been accepted as the most economical galvanic anode especially to large sea structures such as habor and offshore structures, ships, etc., requiring long life corrosion protection. The standard properties of ALUNODE are as shown in Table 1 below.
