省流：早期IBM版T系列是钛合金外壳（wikipedia）；IBM后期三款为镁合金+碳纤维（此后数据都来自联想官网）；联想接手早期为各种PC材料+碳纤维；新的T14系列（黑色）比较乱以PPS/GF，PA/GF，PC/CF为主，特殊的有gen3独显版下盖铝合金，gen4上盖铝合金

作为对比，X1 Carbon系列上盖都是碳纤维，下盖都是镁/铝合金

从T4x（IBM出品的最后三代）到T420如下：

T41
Magnesium composite in the top cover
titanium-reinforced CFRP in bottom cover

T42
Magnesium composite in the top cover
titanium-reinforced CFRP in bottom cover

T43
Magnesium composite in the top cover
titanium-reinforced CFRP in bottom cover

T60
14.1": magnesium composite in top cover, CFRP bottom cover
15": CFRP in top/bottom
