*椴木材质较软,有油脂,耐磨、耐腐蚀,不易开裂,木纹细,易加工,韧性强。适用范围比较广,可用来制作木线、细木工板、木制工艺品等装饰材料。
*椴木的白木质部份通常颇大,呈奶白,逐渐并入淡至棕红的心材,有时会有较深的条纹。这种木材具有精细均匀纹理及模糊的直纹。
*椴木机械加工性良好,容易用手工工具加工,因此是一种上乘的雕刻材料。钉子、螺钉及胶水固定性能尚好。经砂磨、染及抛光能获得良好 的平滑表面。干燥尚算快速,且变形小、老化程度低。干燥时收缩率颇大,但尺寸稳定性良好。 椴木重量轻,质地软,强度比较低,属于抗蒸汽弯曲能力不良的一类木材。 没有心材抗腐力,白木质易受常见家具甲虫蛀食。可渗透防腐处理剂。
*家具用材。为黄白,略轻软,纹理通直,结构略细,有绢丝光泽,有柔软感。木材锯解、旋叨、钻孔、开榫、钉着、胶接、油漆、着等性能良好。树干颈直挺拔,出材率高。椴木为普通木材,材较浅,空隙较大,容易染或漂白。干缩性低,干后不变形不开裂,硬度梢低,不甚耐磨,不甚抗碰抗压。

椴木Basswood
Scientific Name:Tilia americana General Description
The sapwood of Basswood is usually quite large and creamy white in color, merging into the heartwood which is pale to reddish brown, sometimes with darker streaks. The wood has a fine uniform texture and indistinct grain that is straight.
Working Properties
Basswood machines well and is easy to work with hand tools making it a premier carving wood. It nails, screws, and glues fairly well and can be sanded and stained to a good smooth finish. It dries fairly rapidly with little distortion or degrade. It has fairly high shrinkage but good dimensional stability when dry.
Physical Properties
The wood is light and soft with generally low strength properties and a poor steam bending classification.
