To provide a corrosion resistant brass alloy excellent in melting and casting properties, grinding property and abrasiveness as pretreatment for plating.
The corrosion resistant alloy for metallic mold casting and for sand mold casting and metallic mold case product and sand mold cast product are composed by wt.% of 64.0-68.0% copper, 0.3-1.0% tin, 0.5-1.0% nickel, 0.4-0.8% aluminum, 0.01-0.03% phosphorus, 2.0-3.0% lead and as the impurities, ≤0.2% iron, ≤0.02% silicon, ≤0.1% antimony, ≤0.005% chromium and ≤0.01% manganese and the balance zinc. Further, as more desirably, boron is contained by wt.% of 5-10 ppm in the above compositions. Furthermore, a corrosion resistant brass alloy for continuous casting and for a continuous cast product includes 0.03-0.15 wt.% phosphorus in the above composition.
