Selection of Hitachi/Conex EDM Wire Grades

H-BZ-U
U type wire is a standard hard brass wire offered by Hitachi/Conex Cable. This wire has a 60:40 chemical composition and 142,000 psi tensile strength. This allows for faster cutting speed and better cutting accuracy compared to other competitive brass wires. BZ-U wire is relatively stiff and is very straight (low residual cast). Therefore, the automatic connection rate can be raised whether the connection mechanism is pipe type, water jet cutting type, or anneal cutting type. U type wire is made with a slight Paraffin coating to protect the wire surface and ensure a smooth wire feed.

H-BZ-K
K type wire has the same chemical composition and the same tensile strength as U type. K type wire was developed to make an extremely clean and smooth wire surface and to eliminate the powder problems, especially for Mistubishi machines. Hitachi¹s innovative wire die technology enabled this super clean wire surfaces to be available in the U.S. market. BZ-K wire does not require any protective coating to prevent scratches or dents; therefore, BZ-K is a Non-Paraffin coated wire. This wire is highly recommended for any Mitsubishi machine models.

H-BZ-B
B type wire is a unique, high zinc content brass wire with 57:43 chemical composition. This wire is very suitable for most economical, faster cutting EDM operations. Compared to other standard brass wires with 65:35 chemical composition, B wire can reach approximately 8 to 10% faster cutting speeds for various applications. BZ-B is a good alternative to Zinc coated wire for faster cutting speed and more economical than any other coated wires. This results in less adherence of cut powder to the surface so you can improve the surface precision and finishing.

ACZ/ABZ
ACZ is a standard annealed wire offered by Hitachi/Conex Cable. ACZ wire has 60:40 chemical composition to optimize the cutting speed. Tensile strength of ACZ wire is 64,000 psi or over and the elongation is over 15%. ACZ is suitable for moderate angle taper cutting such as 10 to 15 degree angles. ABZ is also available in a 65:35 chemical composition. This wire is specially made for European machines such as Charmilles or AGIE. The software of European machines requires use of the standard chemical composition and wire with a higher zinc content may not work as well. Hitachi/Conex will provide the 65:35 composition wire wound on a DIN type spool for European machines.

ABZ-T
ABZ-T is a very specialized annealing wire with a conventional 65:35 chemical composition. T is a strong, highly flexible wire developed with Hitachi¹s thermal processing technology. It has 20% elongation and up to 71,000 psi tensile strength. BZ-T is very suitable for working on thick pieces and allows taper cutting of wide angles, 10 to30 degrees. When working on thick pieces or performing high taper angle cutting, BZ-T wire prevents the deflection of the object from a guide by raising tension. This surface treatment method enhances the sliding nature on the guide surface, which reduces taper angle and shape errors.

Hitachi Zn Coated Wire ­ Hi-Falcon
Hitachi has developed a new Zn coated EDM wire, named Hi-Falcon, under the unique and new patent pending process. By using high conductive core material, the discharge characteristics of the wire are enhanced. The outside layer has a very uniformly diffused surface with approximately 30 m wall thickness and higher Zn contents. As a result, Hi-Falcon can maintain the constant discharging during the operation even on thicker work piece. In addition, thermal resistant core material provides excellent tensile strength during the operation. Hi-Falcon is very suitable for both speed cutting and fine finish application.
