We produce oxygen-free copper seamless tubes and phosphorous deoxidized copper seamless tubes, both with 99.9% or more copper. All these tubes have high electric and thermal conductivity and are excellent in workability such as malleability, ductility, flaring, pliability and also are excellent in corrosion resistance and weather fastness.

Major products and their uses

• Heating tubes and cooling tubes for air conditioners and refrigerators.
• Copper tubes for plumbing, propane, tap water, gas water heaters and circulating water for bath tubs.
• Special items: copper clad steel (beams for electrical experimentation), and other types of irregular shape copper and brass tubes, terminals and sleeves.

Brass tubes are made of copper and zinc of which the most common composition of ours is 65% copper and 35% zinc. Brass tubes are excellent in flaring, pleability, drawability and plating. Our alloy tubes include those containing 70% copper and 30% zinc and, for special applications, red brass tubes made of 85-90% copper and 15-10% zinc.

Major products and their uses

• Tubes for plumbing (tubes for sanitary plumbing parts)
• Automotive radiators, parts and components
• Pneumatic carriers and related fixtures
• Sprayers for agriculture and various types of cylinders for fire extinguishers
• Parts for daily sundries and stationery printing
• Electrical parts such as antennas and tuners
• Architectural metal ornamentation such as door handles, arm rails and foot rails
