Excellent machining properties with drilling, countersinking, milling, tapping and turning. Conventional HSS-tools can be used at<br />
maximum speeds and feeds. The material guarantees good polishability. <strong>Aluminium</strong> as per EN AW 7075 can be machined on any spark<br />
erosion-machine at metal removal rates and very acceptable levels. The usage of copper and graphite electrodes, as well as reduced<br />
current and spark gap will result in improved surface finishes.<br />
