Product Description

ASTM A254-97 DC04 4*0.6mm Double Wall Copper coated Bundy Tube

 

Double Wall Brazed Steel Tube possesses higher withstanding pressure and higher vibration fatigue strength. Furthermore, the tube is also equipped with superior properties such as solderability, traceability, bendability, and workability in end terminal preparation. As a pressure tubing material with extensive reliability and good processing characteristics, this tube is used for several purposes, such as brake tubing, the power steering on vehicles, and many more.

 

Double Walled Steel Tubing is a steel tube for pressure piping, which is manufactured from electrolytic copper-coated steel strip (both surfaces). The strip is wound into a continuous tubular with a double-layered wall and then copper brazed in a special furnace using the coated copper as filler metal.
