                                   大理石直角尺特性及材質 
                1、巖石經長期天然形成,組織結構均勻,線脹系數 小,內應力完全消失,不變形,因此精度高。

                2、剛性好,硬度高,耐磨性強。
                3、不怕酸,鹼液物侵蝕,不會生銹,不必涂油,不易粘微塵,維護,保養方便簡單,使用壽命長。
                4、不會出現劃痕,不受恒溫條件阻止,在常溫下也能保持測溫量精度。

                   大理石直角尺材質材質
                   主要礦物成份為輝石,斜長石,少量橄欖石,黑云母以及微量磁鐵礦,黑色色澤,結構精密,經過億萬年的老化,質地均勻,穩定性好、強度大、硬度高,能在重負荷下保持高精度。適用于工業生產和實驗室的測量工作。
