Specification-led brass supply
Choose the alloy around the service, then define the order.
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.

Frequently asked questions about Aluminium Brass Tubes
What is C68700 aluminium brass?+
It is an aluminium-bearing copper-zinc alloy commonly designated CuZn20Al2 or CW702R and used for condenser and heat-exchanger tubing.
What is the published chemistry reference?+
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.
Which tests should an RFQ mention?+
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.
How does C68700 differ from C44300?+
C68700 contains aluminium; C44300 contains tin and an inhibitor. Selection depends on cooling medium, velocity, equipment design and the approved material specification.
