Copper Alloy Tubes
Copper Nickel tubes, 30% – C71500 -
Copper Nickel tubes, 30% – C71500 - has, in general, the best resistance of any of the copper alloys to impingement attack and to corrosion from most acids and waters. It is being used in severe corrosive conditions in which service lives longer than those of other copper alloys are desired.
