Frequently Asked Questions
What is C27400 63/37 lead free brass tube?
C27400 is a yellow brass containing approximately 63 per cent copper and 37 per cent zinc. It is used for tubular components, fittings and general engineering applications where the grade and material condition suit the requirement.
Is C27400 the same as C27200?
No. Both are associated with 63/37 yellow brass, but they are separate UNS grades with different copper limits. C27400 contains 61.0 to 64.0 per cent copper, while C27200 contains 62.0 to 65.0 per cent.
Is C27400 really lead free?
No lead is intentionally added, and the composition supplied in this brief limits lead to 0.10 per cent maximum. Confirm the material certificate and applicable regulations before using it in a regulated application.
What is the difference between C27400 and C26000?
C26000 is commonly known as cartridge brass and contains a higher proportion of copper. C27400 is a 63/37 yellow brass. The grades differ in composition and forming characteristics, so select the grade specified for your component.
Is C27400 suitable for drinking water or seawater?
Not automatically. C27400 may be vulnerable to dezincification in certain water conditions. Confirm potable water requirements and certification, and review the material selection carefully for aggressive water or seawater service.
Which standard covers C27400 brass tube?
ASTM B135 is identified in the brief as a seamless brass tube standard, but its applicability to the specific C27400 product should be verified. Confirm the standard, grade, temper and dimensions on your order.
What sizes and forms of C27400 do you supply?
Available forms, sizes, tempers and tolerances must be confirmed for your requirement. Share the outside diameter, wall thickness, length, quantity and drawing with our enquiry team for review.
Do you provide mill test certificates?
Certificate type and test details should be confirmed during quotation. State whether you require chemical analysis, mechanical results, traceability or third party inspection so the documentation can be reviewed for your order.
