High-strength corrosion-resistant copper alloy

The invention discloses a high-strength corrosion-resistant copper alloy, and belongs to the field of copper alloys. The high-strength corrosion-resistant copper alloy comprises 0.05%-0.15% of Ni (nickel), 0.25%-0.45% of P (phosphorus), and the balance Cu (copper) and impurities with the content of less than 0.005% by mass, and the content of the Cu is no less than 99.40%. The tensile strength (annealed soft state) of the alloy is larger than 230 Mpa, and is higher 12% or above than the tensile strength of conventional TP2; the bursting pressure of the alloy in the same specification is further improved by 12% or above, and the corrosion resistance is about 6 times the corrosion resistance of the conventional TP2. 本发明公开了高强度耐腐蚀铜合金，属于铜合金领域，本发明的高强度耐腐蚀铜合金，以质量％计含有0.05％～0.15％的Ni(镍)和0.25％～0.45％的P(磷)，余量为Cu(铜)和含量小于0.005％的杂质，Cu的含量不小于99.40％。本合金的的抗拉强度(退火软态)大于230Mpa，比常规TP2高出12％以上，同规格爆破压力也提升了12％以上，耐腐蚀性能约是常规TP2的6倍。
