Good Quality Material

The copper alloy is solid and well-cast. Shipping took a bit longer than expected, but the product itself meets our workshop standards.

Great Value for Money

Good price for centrifugally cast copper. It serves our purpose well for bearing shell blanks. Would purchase again for future projects.
