Copper alloy tubing

With its corrosion resistance, good workability, and economy, copper tubing is great for plumbing. It is used for various plumbing applications including supplying hot and cold water, in air conditioning, and in various medical fields.

With grooves inside and outside the tubing, smaller diameter tubes can still provide excellent heat transfer.We supply a range of products, including items with small and large fins, and also complex-geometry high-performance tubing.

Copper alloy tubing, with its excellent corrosion resistance in seawater, is used in power plants and in condenser tubing for seawater desalination.

Clad tubing
STC copper tubing
Copper foil

Clad tubing is widely used, in residential air-conditioning refrigerant plumbing, building facilities, and for medical use and so forth.

The interior of STC copper tubing is coated with zinc, to keep the loss of ionized copper to a minimum.It has good resistance to pitting and erosion.

This is used for electronic parts, lithium-ion batteries, and in construction materials.
