Grade: YT5P30 density :12.5-13.2 Flexural strength: 1430 Hardness: 89.5 Application: Carbon and Alloy Steel uneven surface and interrupted cutting roughing. EDM electrodes: tungsten steel, high temperature super-hard alloy die to be produced by electrolysis, the common electrode wear big, slow. The tungsten and copper corrosion, high speed, low loss rate, the exact shape of the electrode, excellent processing performance, to ensure the accuracy of the workpiece to be greatly increased.
