材料导热系数总表(比较齐全)

定义：导热系数是指在稳定传热条件下，1m厚的材料，两侧表面的温差为1度（K,°C）,在1小时内，通过1平方米面积传递的热量，单位为瓦/米·度（W/m·K,此处的K可用°C代替）。导热系数与材料的组成结构、密度、含水率、温度等因素有关。非晶体结构、密度较低的材料，导热系数较小。材料的含水率、温度较低时，导热系数较小。通常把导热系数较低的材料称为保温材料(我国国家标准规定，凡平均温度不高于350℃时导热系数不大于0.12W/(m·K)的材料称为保温材料），而把导热系数在0.05瓦/米摄氏度以下的材料称为高效保温材料。材料名称导热系数W/mK分类描述A356159A360113A38096ABS0.25-0.9ADC1296Ag银429Ag99.9%411Air空气0.01-0.04Al纯铝237硬铝1774.5%Cu铸铝1634.5%CuAl2O3蓝宝石45AlN150Au金315-317千卡/米·时·℃[kcal/(m·h·℃)]卡/厘米·秒·℃[cal/(cm·s·℃)]瓦/米·K[W/(m·K)]焦耳/厘米·秒·℃[J/(cm·s·℃)]英热单位/英尺·时·℉[Btu/(ft·h·℉)]12.78×10-31.161.16×10-20.6723601418.74.1872420.85982.39×10-3110-20.57885.980.239100157.81.494.13×10-31.731.73×10-21Cu纯铜398-401黄铜70-10930%Zn青铜26-3225%Sn康铜20.9温度30Diamond钻石2300Fe铁80FR40.2GaAs46GaP77LTCC2HDPE0.33H2SO4（5-25）0.47-0.590%硫酸0.354HTCG—I450-600HTCG—II350-450ICE冰2.22Kovar17.3LDPE0.33Mg镁1480.6%MuNi纯镍90PA0.25Pb纯铅35PC0.2PMMA0.14-0.2PP0.21-0.260.25PP+25％玻纤PVC0.14软质PVC0.17硬质PS0.08PU0.25Rubber橡胶0.19-0.26Si150Silica纯硅胶0.35中密度硅胶0.17低密度硅胶0.12SiO27.6玻璃0.12玻璃钢0.4普通冕玻璃1温度20石英玻璃1.46温度4燧石玻璃0.795温度32重燧石玻璃0.78温度12.5精制玻璃0.9温度12SiC490Sn纯锡64-67Snow新下的雪0.1填实了的雪0.21STCG—I750STCG—II600-700Steel36-540.5%C殷钢11温度30Ti纯钛14.63Water水0.5-0.7重水0.559水蒸汽0.0235-0.025重水蒸汽0.072Wood木材0.14-0.17横向木材0.38纵向落叶松木0.13温度0普通松木0.08-0.11温度45杨木0.1温度100白桦木0.15温度30橡木0.17温度20雪松0.095温度0柏木0.1温度20Zi112ZL102168ZL1041551070型铝合金2261050型铝合金209AL60636063型铝合金201AL60616061型铝合金155-160AL7075130泡沫塑料0.045环氧树脂0.2-2.2普通粘土砖0.7-0.8耐火砖1.06水泥沙0.9～1.28拌石水泥1.5瓷砖1.99石棉0.15-0.37温度0玄武岩2.18花岗岩2.6～3.6石蜡0.12蜡0.04石蜡油0.123石油0.14沥青0.699沥青0.7纸板0.06～0.14铸铁42～90不锈钢17铸铝138～147导热硅0.8-3亚麻布0.09温度50木屑0.05温度50海砂0.03温度20研碎软木0.04温度20压缩软木0.07温度20聚苯乙烯0.08温度100硫化橡胶0.22-0.29温度50镍铝锰合金32.7温度0镍铬合金12.3-171温度30纸0.06-0.13温度12纸板0.14皮棉0.03温度4.1皮革0.18-0.19矿渣棉0.05-0.14温度0毡0.04瓷1.05汽油0.11温度12变压器油0.128柴油机燃油0.12“天然气”油0.14温度12甘油0.276温度0煤油0.12温度100蓖麻油0.18温度500橄榄油0.165温度0凡士林0.184温度12玄武岩2.177花岗石2.68～3.35丙酮0.177苯0.139已烷0.152温度0二氯乙烷0.147醋酸18硝基苯0.159二硫化碳0.144甲醇0.207四氯化碳0.106三氯甲烷0.121氨气0.022硫化氢0.013聚苯板0.04胶合板0.125温度0木工板0.1-0.2纤维素0.46温度0丝0.04-0.05温度20炉渣0.84温度50硬质胶0.18温度50常用材料的导热系数表用途材料名称密度(kg/m3)导热系数(W/m.K)窗框铜8900380硅合金铝2800160黄铜8400120铁780050不锈钢790017PVC13900.17硬木7000.18建筑构件软木5000.13UP树脂玻璃钢19000.4玻璃碳酸钙玻璃25001.0有机玻璃PMMA11800.18聚碳酸脂12000.2热断桥聚冼氨尼龙11500.256.6%尼龙,25%玻璃纤维14500.3高密度聚乙烯HD9800.5低密度聚乙烯LD9200.33固体聚丙烯9100.2225%玻纤聚丙烯12000.25聚亚氨脂树脂PU12000.25刚性PVC13900.17防雨氯丁橡胶PCP12400.23密封条三元乙丙EPDM11500.25纯硅胶12000.35柔性PVC12000.14聚脂马海毛0.14柔性橡胶泡末60-800.05密封剂刚性聚氨脂PU12000.25固体/热融异丁烯12000.24聚硫胶17000.4纯硅胶12000.35聚异丁烯9300.2聚脂树脂14000.19硅胶干燥剂7200.13分子筛650-7500.1低密度硅胶泡末7500.12中密度硅胶泡末8200.17表2窗体材料导热系数窗框材料钢材铝合金PVCPA松木导热系数58.22030.160.230.17表3不同玻璃的传热系数玻璃类型玻璃结构(m)传热系数K-w/(m2-k)单层玻璃6.2双层中空玻璃5×9×53.265×12×53.11一层中空玻璃5×9×5×9×52.22←--5×12×5×12×52.08Lhw-E中空玻璃5×12×51.71常用材料导热系数--深圳智通电子有限公司提供MetalMaterialConductivityDensityW/m-Ckg/m3Aluminum,2024,Temper-T31212.80E+03Aluminum,2024,Temper-T3511432.80E+03Aluminum,2024,Temper-T41212.80E+03Aluminum,5052,Temper-H321382.68E+03Aluminum,5052,Temper-O1442.69E+03Aluminum,6061,Temper-O1802.71E+03Aluminum,6061,Temper-T41542.71E+03Aluminum,6061,Temper-T61672.71E+03Aluminum,7075,Temper-O1302.80E+03Aluminum,7075,Temper-T61302.80E+03Aluminum,A356,Temper-T61282.76E+03Aluminum,Al-Cu,Duralumin,95%Al-5%Cu1642.79E+03Aluminum,Al-Mg-Si,97%Al-1%Mg-1%Si-1%Mn1772.71E+03Aluminum,Al-Si,Alusil,80%Al-20%Si1612.63E+03Aluminum,Al-Si,Silumim,86.5%Al-1%Cu1372.66E+03Aluminum,Pure2202.71E+03Beryllium,Pure1751.85E+03Brass,Red,85%Cu-15%Zn1518.80E+03Brass,Yellow,65%Cu-35%Zn1198.80E+03Copper,Alloy,110003888.93E+03Copper,Aluminumbronze,95%Cu-5%Al838.67E+03Copper,Brass,70%Cu-30%Zn1118.52E+03Copper,Bronze,75%Cu-25%Sn268.67E+03Copper,Constantan,60%Cu-40%Ni22.78.92E+03Copper,DrawnWire2878.80E+03Copper,Germansilver,62%Cu-15%Ni-22%Zn24.98.62E+03Copper,Pure3868.95E+03Copper,Redbrass,85%Cu-9%Sn-6%Zn618.71E+03Gold,Pure3181.89E+04Invar,64%Fe-35%Ni13.88.13E+03Iron,Cast557.92E+03Iron,Pure71.87.90E+03Iron,Wrought,0.5%C597.85E+03Kovar,54%Fe-29%Ni-17%Co16.38.36E+03Lead,Pure351.14E+04Magnesium,Mg-Al,Electrolytic,8%Al-2%Zn661.81E+03Magnesium,Pure1711.75E+03Molybdenum1301.02E+04Nichrome,80%Ni-20%Cr128.40E+03Nickel,Ni-Cr,80%Ni-20%Cr12.68.31E+03Nickel,Ni-Cr,90%Ni-10%Cr178.67E+03Nickel,Pure998.91E+03Silver,Pure4181.05E+04Solder,Hard,80%Au-20%Sn571.50E+04Solder,Hard,88%Au-12%Ge881.50E+04Solder,Hard,95%Au-3%Si941.57E+04Solder,Soft,60%Sn-40%Pb509.29E+03Solder,Soft,63%Sn-37%Pb519.25E+03Solder,Soft,92.5%Pb-2.5%Ag-5%In391.20E+04Solder,Soft,95%Pb-5%Sn32.31.10E+04Steel,Carbon,0.5%C547.83E+03Steel,Carbon,1.0%C437.80E+03Steel,Carbon,1.5%C367.75E+03Steel,Chrome,Cr0%737.90E+03Steel,Chrome,Cr1%617.87E+03Steel,Chrome,Cr20%227.69E+03Steel,Chrome,Cr5%407.83E+03Steel,Chrome-Nickel,15%Cr-10%Ni197.87E+03Steel,Chrome-Nickel,18%Cr-8%Ni16.37.82E+03Steel,Chrome-Nickel,20%Cr-15%Ni15.17.83E+03Steel,Chrome-Nickel,25%Cr-20%Ni12.87.87E+03Steel,Invar,36%Ni10.78.14E+03Steel,Nickel,Ni0%737.90E+03Steel,Nickel,Ni20%197.93E+03Steel,Nickel,Ni40%108.17E+03Steel,Nickel,Ni80%358.62E+03Steel,SAE1010597.83E+03Steel,SAE1010,Sheet63.97.83E+03Steel,Stainless,31616.268.03E+03Steel,Tungsten,W0%737.90E+03Steel,Tungs
