Product Overview

Copper Alloy Products by Fineweld Tube

Fineweld Tube manufactures welded copper alloy tubing from flat-rolled strip via the high frequency induced current method, also known as the “forge-welded process.” This process involves heating the strip edges to a plastic state, then  forging them together to create a metallurgically sound weld. No filler metals are used.
