Insimbi ye-calcium noma i-metallic calcium iyinsimbi emhlophe esiliva.Isetshenziswa kakhulu njenge-deoxidizing, decarburizing, ne-ejenti ye-desulfurizing ensimbi ye-alloy kanye nokukhiqizwa kwensimbi okukhethekile.Ibuye isetshenziswe njenge-ejenti yokunciphisa ezinqubweni zensimbi zomhlaba ezingavamile ezihlanzekile kakhulu.
I-calcium iyinsimbi emhlophe esiliva, eqinile futhi esindayo kune-lithium, i-sodium, ne-potassium;iyancibilika ku-815°C.Amakhemikhali e-metallic calcium asebenza kakhulu.Emoyeni, i-calcium izokwenziwa i-oxidized ngokushesha, ihlanganise ungqimba lwefilimu ye-oxide.Lapho kushisa, i-calcium iyavutha, ikhiphe ukukhanya okuhle okubomvu kwezitini.Isenzo se-calcium namanzi abandayo sihamba kancane, futhi ukusabela kwamakhemikhali anobudlova kuzokwenzeka emanzini ashisayo, kukhishwe i-hydrogen (i-lithium, i-sodium, ne-potassium nayo izobhekana nokusabela kwamakhemikhali okunobudlova ngisho nasemanzini abandayo).I-calcium nayo kulula ukuyihlanganisa ne-halogen, isulfure, i-nitrogen nokunye.
