材料导热系数总表(比较齐全)

常见材料导热系数全1.金属材料：-银：429W/(m·K)-铜：401W/(m·K)-铝：237W/(m·K)-铁：80.4W/(m·K)-钨：173W/(m·K)2.石材材料：-大理石：2.5W/(m·K)-花岗岩：2.7W/(m·K)-砂岩：1.9W/(m·K)-石灰石：1.8W/(m·K)-人造石：1.1W/(m·K)3.绝缘材料：-玻璃纤维：0.04-0.05W/(m·K)-膨胀聚苯乙烯（EPS）：0.035W/(m·K)-聚氨酯：0.022W/(m·K)-聚苯板：0.015W/(m·K)-聚氨酯泡沫：0.02-0.03W/(m·K)4.建筑材料：除了石材和绝缘材料外，其他一些常见的建筑材料的导热系数也不同：-砖：0.6-1.0W/(m·K)-水泥：1.8-2.4W/(m·K)-水泥砂浆：0.7-1.2W/(m·K)-红砖：0.6-0.8W/(m·K)-玻璃：0.7-1.0W/(m·K)5.塑料材料：-聚乙烯：0.33W/(m·K)-聚氯乙烯（PVC）：0.19W/(m·K)-聚丙烯：0.22W/(m·K)-聚苯乙烯（EPS）：0.035W/(m·K)-聚酯：0.15W/(m·K)需要注意的是，以上列举的导热系数只是一些常见材料的典型值，实际应用中可能会有一定差异。

此外，材料的导热系数还受到温度、密度、含水率等因素的影响。

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。

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。

材料导热系数总表比较齐全公司标准化编码 [QQX96QT-XQQB89Q8-NQQJ6Q8-MQM9N]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、、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(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。

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。

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。
