【黑胡桃木】Black Walnut 學名:Juglans nigra 胡桃科胡桃屬落葉樹 分佈在美東、加拿大奧大略的黑胡桃木,與柚木、紫檀、桃花心木並列為世界高級木材。日本曾經一度過度流行使用在傢俱、內裝上,而造成了美國禁止黑胡桃木原木的出口,加上現在林地幾乎都已開發為農地的緣故,蓄積量變得非常少。 黑胡桃木的心材與邊材界線清楚,邊材為白色,而心材在剛採伐時為淺褐色,過一段時間後會轉為深褐色。日照較多的木材顏色較深,反之較淺。 黑胡桃木的木紋優美,稍微加工即能展現出豔麗的光澤,加上耐久性佳,心材不易受到蟲害,從過去到現在都是高級傢俱、樂器和工藝用材,也被用在地板材與內裝板材上。由於黑胡桃木樹幹直挺,廢材率低,以木材而言,是相當有價值的樹種。 #黑胡桃木 #木材資料庫
