Raw Materials – Metal & Graphite

Saturn offers a range of metal EDM electrodes in a variety of materials, including copper, copper tungsten, tellurium copper, brass, tungsten and many special alloys.

For as long as we have been a manufacturer of EDM electrodes, we have also been a supplier of EDM electrode materials. In fact, Saturn was the first company dedicated to supplying electrode materials specifically for the EDM industry. Today, we are a major industry source of both graphite and metal electrode materials. Because we maintain one of the world’s most comprehensive inventories of EDM materials, we probably have exactly what you need, and can fill your order immediately. 80% of our orders are shipped the same day.

When it comes to metals used for EDM electrodes, Saturn’s know-how is unsurpassed. We carry the broadest line of EDM metals in the industry including a wide assortment of wire, solid rounds, tubes and flat bars, available in quantity for immediate delivery.

GRAPHITE

Graphite electrodes are by far the most popular EDM electrodes used in the United States. Here at Saturn we feel that it is important to give our customers what they want and in doing so offer everyone a choice in the brand of graphite they purchase. We can provide the full lines of POCO, Ibiden, Carbone of America, and Toyo Tanso. We hold stock in the standard electrodes such as tubes, rods, sheets, plates, squares, blocks, and tapping electrodes. Saturn has also lead the way in producing electrodes to print and electrodes unique in graphite such as rototubes, and small letters and numbers. Saturn Industries also produces graphite blanks in any of the above mentioned brands. We can manufacture your graphite blank to any specific size you might need in both ground and sawcut finishes. On most ground items we are pleased to offer a standard tolerance of ±.0002.

Our team of engineers and machinists work collabortively to guarantee our customers satisfaction. Saturn’s graphite electrodes are carefully crafted to meet highly specific parameters. These include level of detail, material, strength, wear resistance, processing speed, surface finish, and cost.
