Fineweld Tube

A World Leader in Copper Tubing

Olin Brass Fineweld® Tube is a business unit of Olin Brass, and a world leader in its own right. Developed in Olin Brass Metals Research Laboratory, Fineweld Tube was initially commercialized in 1968 and quickly rose to a dominant market position in high-frequency welded copper alloy tubing.

Today, we specialize in tubing products manufactured from copper-nickel alloys designed for heat transfer and other applications that demand superior surface quality. We serve public and private customers in a wide range of markets, including power utility, desalination, air conditioning and refrigeration, architectural hardware, plumbing and plumbing products, and redraw.

Product Overview

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.
