Your Copper Casting Questions Answered

How small can the products be?

We regularly produce medical device components under 10g with 0.3mm wall thicknesses.

Do you handle post-casting machining?

Yes – our in-house CNC workshop achieves Ra 1.6μm surface finishes for bearing surfaces.

What alloys prevent dezincification in seawater?

We recommend C46400 naval brass or C68700 aluminum brass for marine hardware.

Can you match historical alloy compositions?

Our metallurgists successfully replicated 19th-century C90300 gunmetal for museum restorations.
