Match C68700 tubing to the cooling medium, velocity, OEM specification, dimensions and required examination before procurement.

Specification-led brass supply
Aluminium brass C68700 is a copper-zinc-aluminium alloy used for heat-transfer tubing. Aluminium content of 1.8–2.5% supports formation of a protective surface film under suitable service conditions.
Specify the alloy and finished-tube standard together. Confirm water conditions, temper, tube-sheet or bending operations, eddy-current scope and any stress-corrosion test before quotation.
A clearer route to purchase
Write the UNS or EN grade and product standard on the enquiry.
State OD or nominal size, wall, length, tolerances and form.
Identify MTC, examination, marking and inspection before quotation.

Before requesting a quotation
It is an aluminium-bearing copper-zinc alloy commonly designated CuZn20Al2 or CW702R and used for condenser and heat-exchanger tubing.
A common ASTM B111 reference lists copper 76–79%, aluminium 1.8–2.5%, arsenic 0.02–0.06%, with zinc as the remainder. The governing standard and MTC control acceptance.
State the required eddy-current or hydrostatic examination, any nitrate or stress-corrosion test, MTC type and third-party inspection rather than assuming they are included.
C68700 contains aluminium; C44300 contains tin and an inhibitor. Selection depends on cooling medium, velocity, equipment design and the approved material specification.
