磷脱氧铜焊接性能和冷弯性能好，一般无“氢病”倾向，可在还原性气氛中加工、使用，但不宜在氧化性气氛中加工、使用。TP1的残磷量比TP2少，故其导电、导热性较TP2高。TP1和TP2主要以管材应用，也可以板、带或棒、线供应。用作汽油或气体输送管、排水管、冷凝管、水雷用管、冷凝器、蒸发器、热交换器、火车箱零件。 化学成份： 铜+银 Cu+Ag：≥99.85 锡 Sn ：≤0.01 铅 Pb：≤0.005 磷 P：0.013～0.050 镍 Ni：≤0.01 铁 Fe：≤0.05 锑 Sb ：≤0.002 硫 S ：≤0.005 砷 As ：≤0.005 铋 Bi：≤0.002 氧 O：≤0.01 注：≤0.15(杂质) 力学性能 ●力学性能： 抗拉强度 σb (MPa)：215～275 伸长率 δ10 (%)：≥25 硬度 ：55～100HV 注 ：带材的室温拉伸力学性能 试样尺寸：厚度≥0.3 状态：磷脱氧铜带材(1/4硬,≥0.3mm) DHP Copper tubes - C12200 - Phosphorus-Deoxidized copper tubes – C12200 - are extensively used in sugar refineries for condensers and evaporators. Deoxidized copper is the standard material for transferring heat from steam to water or air because of their excellent resistance to corrosion by fresh water and their high thermal conductivities.
