紫铜管的重量计算公式 ,紫铜就是纯铜: 纯铜呈紫红色,又称紫铜。纯铜密度为8.96,熔点为1083℃, 紫铜管的质量计算如下:G=8.96πδ(D-δ)/1000 G:质量kg δ:管壁厚mm D:管直径mm 适宜制造紫铜管铜材的牌号为T1、T2。 T1T2 T1的化学成份 Cu+Ag99.95%,P0.001%,Bi0.001%,Sb0.002%,As0.002%,Fe0.005%,Ni0.002%,Pb0.003%,Sn0.002%,S0.005%,Zn0.005%,O0.02%。 T2的化学成份 Cu+Ag99.95%,Bi0.001%,Sb0.002%,As0.002%,Fe0.005%,Pb0.005%,S0.005%。 导热率(λ)384/W·(m·K)-1 比热熔(C) 0.394/kj·(kg·K)-1
