Characteristics:
The products made by the process of vaccum casting,forging and heat treatment have compact grain and high-density organization without any defect.
The material of Cu-Cr-Zr has higher physical mechanical properities than that of traditional chromium bronze.
The electrode holders are made by vacuum casting directly or cast with copper pipe for water passage.
