In order to determine the material of the main transformer terminal, the electrical conductivity, mechanical properties and stress corrosion resistance of brass alloy terminal were studied by XRD, mechanical properties test and ammonia fumigation test. The results show that H59 alloy consists of (Cu, Zn) phase, Cu 5 Zn 8 phase and CuZn phase, H70 alloy consists of (Cu, Zn) phase and dendritic Cu 0.64 Zn 0.36 phase, H80 alloy and H90 alloy are both (Cu, Zn) phase. With the increase of Cu content, the strength of brass decreases, the conductivity increases, and the stress corrosion resistance increases. H90 alloy has excellent plasticity and toughness, excellent resistance to ammonia fumigation stress corrosion, and can be used as main transformer terminal material.
