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(m·K)的材料称为保温材料），而把导热系数在瓦/米摄氏度以下的材料称为高效保温材料。焦耳/厘英热单位/英千卡/米·时·℃卡/厘米·秒·℃瓦/米·秒·℃尺·时·℉·℃)][cal/(cms·℃)]米·K[W/(m·K)][kcal/(mh[J/(cm·s·℃)][Btu/(ft·h·℉)]1×10-3×10-23601242×10-3110-21001×10-3×10-21导热系数分类描述材料名称W/mKA356159A360113A38096ABS银429Ag%411Air空气纯铝237硬铝177%Cu铸铝163%CuAl2O3蓝宝石45AlN150Au金315-317Cu纯铜398-401黄铜70-10930%Zn青铜26-3225%Sn康铜温度30Diamond 钻石 2300Fe铁80FR4GaAs46GaP77LTCC2HDPEH2SO4（5-25）硫酸HTCG—I450-600HTCG—II350-450ICE冰KovarLDPEMg镁148%MuNi纯镍90PAPb纯铅35PCPMMA玻纤PVC软质PVC硬质PSPURubber橡胶纯硅胶中密度硅胶低密度硅胶SiO2玻璃玻璃钢普通冕玻璃1温度20石英玻璃温度4燧石玻璃温度32重燧石玻璃温度精制玻璃温度12SiC490Sn纯锡64-67Snow新下的雪填实了的雪STCG—I750STCG—II600-700Steel36-54%C殷钢11温度30Ti纯钛Water水重水水蒸汽重水蒸汽Wood木材横向木材纵向落叶松木温度0普通松木温度45杨木温度100白桦木温度30橡木温度20雪松温度0柏木温度20Zi112ZL102168ZL1041551070型铝合金2261050型铝合金209AL60636063型铝合金201AL60616061型铝合金155-160AL7075130泡沫塑料环氧树脂普通粘土砖耐火砖水泥沙～拌石水泥瓷砖石棉温度0玄武岩花岗岩～石蜡蜡石蜡油石油沥青沥青纸板～铸铁42～90不锈钢17铸铝138～147导热硅亚麻布木屑海砂研碎软木压缩软木聚苯乙烯硫化橡胶镍铝锰合金镍铬合金纸
