用该合金作为触媒合成金刚石可提高其强度，并随渗氮层厚度的增加强度也增加。

When the a1loy is used to synthesize the diamond, strength of the diamond is increased, and the thicker the nitriding case, the higher the strength.

液体渗氮可以获得厚度为0.001到0.012英寸（0.03~0.30mm）的硬化层，然而气体渗氮则能获得厚0.025英寸（0.64mm）的硬化层。

Case thickness of 0.001 to 0.012in. (0.03~0.30mm) is obtained, whereas for gas nitriding the case may be as thick as 0.025 in. (0.64mm).
