    • The invention relates to a saw wire consisting essentially of a steel wire, an intermediate layer and a metallic binding phase into which diamond grains with an average diameter of 10 to 50 micrometers are inserted, characterized in that the metallic binding phase has a hardness of between 600 and 1100 HV 0.1 and consists of an inner layer and an outer layer which are arranged concentrically around the steel wire provided with the intermediate layer. The inner layer has a thickness of approximately between 10 and 25% of the average diamond grain diameter, while the thickness of the outer layer is such that the overall thickness of the metallic binding phase is 45-55% of the average diamond grain diameter and the diamond grains have an average interval of not more than 5 times their average diameter. Other fine particles with an average diameter of 1 to 6 micrometers are located between the diamond grains with an average diameter of 10 to 50 micrometers.
    • 本发明涉及一种主要由钢线,中间层和金属结合相组成的锯线,金刚石晶粒的平均直径为10至50微米,其中金属结合相的硬度介于 600和1100HV 0.1,并且由设置有中间层的钢丝同心地配置的内层和外层构成。 内层的厚度约为平均金刚石晶粒直径的10至25%,而外层的厚度使得金属结合相的总厚度为平均金刚石晶粒直径的45-55%, 金刚石颗粒的平均间隔不超过其平均直径的5倍。 平均直径为1至6微米的其它细颗粒位于平均直径为10至50微米的金刚石晶粒之间。
