Recommended Usage: Telco is a machinable copper for EDM. As an electrode material, Telco performs the same as regular copper. However, Telco offers the distinct advantage that is 90% machinable as compared to regular copper (refer to chart below). Telco Electrodes can be machined much faster and easier as compared to regular copper.
|Specification||Free Cutting Brass||Hard Drawn Copper||Telco|
|Relative Machinability Rating||100%||20%||90%|
|Density (lbs. per cu. inch)||.307||.323||.323|
|Approx Wear Ratio into Steel||1:01||2:01||2:01|
Copper Tungsten “CT-3″
Recommended Usage: Copper Tungsten CT -3 is a sintered and infiltrated electrode material which combines the strength, high density, and high melting point of Tungsten with the excellent electrical properties and good resistance against DC arcing of copper to form an unbeatable combination.
Typical Average Properties
|1) Density||14.0 gms/cc|
|2) Rockwell Hardness||90 B|
|3) Electrical Conductivity||48% I.A.C.S.|
|4) Copper Content||25-30%|
|5) Tungsten Content||70-75%|
|*Special Note: CT-3 thin sheets from .001 thick through .055 have a 40% Copper/60% Tungsten content|
TC-9 Tungsten Carbide Tubing
TC-9 Tungsten Carbide electrodes are recommended as an alternative to brass, copper, or copper tungsten for EDMing holes. The extreme high density, strength, good conductivity, and high melting point of TC-9 make it an excellent choice for EDMing production holes where electrode wear is a factor.
Pure Tungsten Wire TU-4
Tungsten wire TU-4 is recommended for EDMing small diameter holes less than .100 deep. Due to its strength, high density, and high melting point, TU-4 electrodes are more resistant to electrode wear than any other electrode material.
