Zusammenfassung: | The invention belongs to the technical field of alloys, and particularly relates to a tin brass alloy and a preparation method thereof. The invention provides the tin brass alloy. The tin brass alloy comprises, by mass, 0.25-0.50% of Ni, 0.15-0.50% of Fe, 0.02-0.08% of P, 0.3-1.5% of Sn, 64-80% of Cu and the balance Zn. Experimental results show that the tensile strength of the tin brass alloy is 560-720 MPa, the yield strength is 520-680 MPa, the elongation is 1-15%, the electric conductivity is 22-27%IACS, the stress relaxation resistance rate at a temperature of 150 DEG C for 1000 h is 70-80%, the minimum R/T value of a strip without cracks after 90-degree bending in the cross-section direction is 0.5, the minimum R/T value of the strip without cracks after 90-degree bending in the longitudinal section direction is 1.5, the dezincification ratio is less than 10%, and the tin brass alloy is corrosion resistant.
