The invention discloses an alloy grid for a storage battery. The alloy grid is characterized by containing the following components in percentage by weight: 0.06%-0.12% of calcium, 0.2%-0.6% of tin, 0.02%-0.04% of aluminum and the balance being lead. In production, the alloy grid can be easily cast-molded, no pollution is caused, the efficiency is high, the performance of a tubular flooded storage battery is not affected, the alloy grid does not embrittle and the service life is long.
