FAQ
Q1: What makes C28800 different from C26000 or C28000 brass?
C28800 contains arsenic, giving it improved corrosion resistance and dezincification resistance compared to standard brasses.
Q2: Is C28800 suitable for marine environments?
Yes. Arsenic-containing brass offers better resistance to water corrosion, making it suitable for marine and plumbing applications.
Q3: Can C28800 Brass be deep drawn?
Yes, it has good cold-working characteristics and is suitable for drawing, though not as ductile as C28000.
Q4: What tempers are available?
O, 1/4H, 1/2H, H, EH depending on product form and customer requirements.
Q5: What surface finishes can you supply?
Mill finish, bright finish, polished, brushed, protective-film-coated strip, custom surface treatments.
Q6: Do you offer slitting or custom cutting?
Yes, we offer precision slitting down to 5 mm width, CNC cutting, and custom sheet/coil dimensions.
Q7: Can you provide MTC and third-party inspection?
Yes. We supply EN10204 3.1 MTC, and third-party inspection such as SGS / TUV / BV upon request.
