FAQ
Q1: What is the difference between C27400 and C26000?
C26000 has higher copper (70%), better strength, and slightly lower formability.
C27400 (CuZn37) is more ductile and better for deep drawing.
Q2: Is C27400 suitable for stamping and bending?
Yes, it is one of the best brasses for cold forming processes such as stamping, bending, and drawing.
Q3: Can C27400 brass be used for heat exchangers?
Yes, its good thermal conductivity makes it suitable for fin materials and cooling components.
Q4: What tempers are commonly available?
O (annealed), 1/4H, 1/2H, H, EH.
Annealed tempers offer the best formability.
Q5: Do you offer surface treatments?
Yes: brushing, polishing, plating preparation, oil-coating, anti-oxidation treatment.
Q6: Can you supply small coils for automatic stamping lines?
Yes, small coils and narrow strips from 10 mm width are available through precision slitting.
Q7: What is your quality standard for burr control?
Burr height ≤ 0.03–0.08 mm, depending on thickness and customer requirement.
Q8: What industries typically purchase C27400 brass?
HVAC, automotive, electrical, building decoration, hardware manufacturing, and musical instrument sectors.
Q9: Is C27400 corrosion-resistant in marine environments?
It performs well in general environments but is not recommended for continuous seawater exposure.
Q10: Do you accept OEM cutting and custom dimensions?
Yes, we support coil-to-sheet cutting, stamping blank sizes, precision slitting, and tailor-made specifications.
