Following one used for Al alloy, You can try with it

Dear Sir. Concerning your issue about the digestion (dissolve) of a ZAMAK alloy for atomic absorption spectroscopy . Accurately weigh a 0.5-g sample and transfer to a beaker or Erlenmeyer flask. Add 20 mL of (1+1) HCl cautiously. If copper (or beryllium) is present, add 30% H2O2 dropwise with gentle heating to dissolve. Complete dissolution may require boiling at low temperature. If silicon is present above I per cent and Mg or Cu are to be accurately determined, filter the silicon on Whatman #40 paper. Wash the paper and residue. Ash, first at 400 °C, then at 1000 °C, in a platinum dish or large crucible. Volatilize the silica by the addition of 5 to 10 mL of HF and 1 mL of HNO3 in a Dutch oven. Dissolve the residue in 1 mL of conc. HCl with gentle heating and combine with the original sample solution, washing the dish or crucible with deionized water to assure complete recovery. Transfer the sample solution and washings to a 100-mL volumetric flask and dilute to volume with deionized water. I think the following below link may help you in your analysis:
