Aluminum casting alloy

The invention relates to the field of metallurgy, in particular to aluminum-based alloys, and can be used for producing thin-walled, complex-shaped castings by casting in metal molds, in particular for automotive parts, parts of electronic devices, and the like. The aluminum-based casting alloy contains: 1.5 to 5.1% by weight of calcium; up to 0.7% by weight of iron; up to 1.0% by weight of silicon; 0.1 to 1.8% by weight of zinc; optionally, one or more of: 0.2 to 2.5 wt% manganese; 0.005 to 0.1% by weight of titanium; from 0.05 to 0.14% by weight of zirconium; 0.05-0.15% by weight of chromium, wherein calcium and zinc are predominantly present in the structure of the alloy in the form of eutectic particles. The technical result is providing a desired combination of process properties and corrosion resistance in casting. 本发明涉及冶金领域，具体地涉及铝基合金，并且可以用于通过在金属模具中铸造来制造薄壁复杂形状的铸件，特别是用于汽车部件、电子器件的零件等。该铝基铸造合金含有：1.5-5.1重量％的钙；至多0.7重量％的铁；至多1.0重量％的硅；0.1-1.8重量％的锌；任选地，以下中的一种或多种：0.2-2.5重量％的锰；0.005-0.1重量％的钛；0.05-0.14重量％的锆；0.05-0.1
