FAQ
Q1: What distinguishes C46700 from standard brass grades?
C46700 offers superior seawater resistance, enhanced SCC resistance, and better high-strength performance compared to regular brass alloys.
Q2: Is C46700 suitable for marine rotating components?
Yes. Its mechanical strength and corrosion resistance make it ideal for propellers, shafts, and seawater pumps.
Q3: Can C46700 be welded and machined?
Yes. It has good machinability and supports TIG/MIG welding with proper copper-alloy techniques.
Q4: Which standards does C46700 comply with?
ASTM B111, ASTM B135, EN 1982, and equivalent naval brass alloy standards.
Q5: Do you offer custom machining or forging?
Yes. OEM rods, plates, hollow bars, and custom-forged shapes are available according to drawings.
Q6: Is C46700 used only in marine applications?
No. It is also used in chemical plants, seawater treatment systems, desalination units, and corrosion-resistant pipelines.
Q7: What certifications can be provided?
