PURPOSE:To give uniformity to the melting surface, by incorporating specific amounts of Ca and/or Ba to the aluminium alloy for a galvanic anode contg. specific amounts of Zn, Mg, In, Sn and Si. CONSTITUTION:The aluminium alloy for a galvanic anode consists of, by weight, 1-10% Zn, 0.1-6% Mg, 0.01-0.04% In, 0.005-0.15% Sn, 0.09-1% Si, and the balance Al. Ca and/or Ba (0.005-0.45wt%) is incorporated to this aluminium alloy. |
