SPARKAL EDM electrodes

During the aluminum casting process, the metal melt is either poured or pressed into the mold. This process is used, for example, to manufacture cylinder heads, wheel rims and many other aluminum castings. Here, the mold has to repeatedly withstand the metal melt at a temperature of over 600 °C: for inserts made of our tungsten-heavy metal alloy Densimet® and the molybdenum alloy TZM, that's not a problem. The benefits to you: — Shorter cycle times — Top surface quality for your products — Long mold service life — No cracks in the mold insert Tailor-made mold inserts, sprue bushes, cooling inserts and other individual parts as well as semi-finished products for your mold are available.

Rods made of the tungsten alloy DENSIMET are available in the diameter range 6mm to 62mm in different lengths in the Plansee Online Shop. Order fast and easily from the producer's online shop: www.plansee.com/shop. Special dimensions are available on request.

Welding electrodes made of tungsten, molybdenum and their alloys are particularly suitable for welding highly conductive materials such as copper. They are used in the following processes: Spot welding, Roller welding, Projection welding, Upset welding. Welding electrodes made from our refractory metals and their alloys have a relatively high level of electrical conductivity while also exhibiting outstanding stability at high temperatures. They therefore have a considerably longer service life than conventional materials such as copper and copper alloys.

The following nozzles and electrodes made of tungsten-copper are available from stock: Nozzles: — PN-F4-6 — PN-F1-6 — PN-G-W / PN-GH-W Electrodes: — PE-F4 — PE-F1-45 / PE-F1-90 — PE-3M63 / PE-7M63 / PE-9M63 Thanks to its high melting point, tungsten ensures that even the high temperatures that occur at the particularly exposed tip cause no damage to the spray nozzle. The high level of thermal conductivity provided by tungsten and copper ensure optimum heat dissipation. As a result, our nozzles and electrodes offer excellent resistance to arc erosion. This guarantees a long service life. — outstanding arc erosion resistance — high temperature resistance — optimum thermal conductivity
