Recommended Usage: Telco is a machinable copper for electrical discharge machining. As an electrode material, Telco performs the same as regular copper. However, Telco offers the distinct advantage of being 90% machinable as compared to regular copper. To view the Telco advantages chart, click here.
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 and Rod
TC-9 Tungsten Carbide electrodes are recommended as an alternative to brass, copper, or copper tungsten for machining holes. The extreme high density, strength, good conductivity, and high melting point of TC-9 make it an excellent choice for processing production holes where electrode wear is a factor. MWI offers a wide range of sizes starting at .005.
Pure Tungsten Wire TU-4
Tungsten wire (TU-4) is recommended for 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. MWI offers a wide range of sizes starting at .002.
MWI supplies the finest consumables available on the market. We offer a full line of products to service all parts of the industry.
