Tubes
Where electrical and thermal conductivity are of highest importance Luvata's oxygen-free copper tubes are the first choice.
Toughness and ductility of oxygen-free copper make it ideal material for phase rings of power generators and other electrical and electronic components. Tubes are available in wide array of sizes and dimensions.
Standard grade OF-OK® oxygen-free copper is the best choice for most of the applications. Small addition of silver increases the softening and relaxation temperature, creep and fatigue strength in elevated temperature copper without significant loss of electrical conductivity. Silver bearing grades CuAg0,04% and CuAg0,1% are recommended for elevated temperature applications where the material is presumed to have load bearing capacity. OFE-OK® electronic grade copper is recommended for vacuum applications.

EN 13600 ‘Copper and copper alloys. Seamless copper tubes for electrical purposes’
ASTM B75 ‘Standard Specification for Seamless Copper Tube’
Tubes for MIG welding and brazing are made of phosphorus deoxidized copper EN CW024A and ASTM C12200. Tubes are manufactured by cold drawing using mandrel inside the tube. As a result the ID surface is very smooth and precise in dimension.
Available tube forms; round, hexagonal and oval.
