<p>The invention relates to a magnesium alloy particularly useful for squeeze casting containing 10 to 25% zinc, 0.5 to 5% copper and 0.25 to 4% silicon, the balance being magnesium and aluminium being substantially absent from the alloy. Additions may include up to 1% calcium with a preferred 0.3% calcium, and 0.002 to 0.005% beryllium. The preferred composition is 12% zinc, 1% copper, 1% silicon, balance magnesium, although 0.3% calcium is a preferred addition to this alloy. The alloy is particularly useful for squeeze casting of automotive and aerospace components.</p> |
