Absolutely. We provide custom thickness, width, precision tolerances (down to ±0.005 mm for strips), and custom cut-to-length services based on customer drawings.
Q9: What is the difference between C27200 and C26000 Brass?
C27200 (63/37 brass) → Better for cold working and deep-drawing
C26000 (70/30 brass) → Better corrosion resistance and electrical conductivity
Both are widely used, but C27200 is preferred for stamped and drawn parts.
Q10: Do you provide third-party inspection?
Yes. SGS, TUV, BV, Intertek inspections can be arranged. Full QC reports and mill certificates are also available.
