Copper Ingots Q & A
Q: What’s the difference between copper ingots and copper cathodes?
A: Ingots are cast into blocks for easy transport and melting, while cathodes are thin sheets used in electrolytic processes.
Q: How do I verify copper ingot purity?
A: Request a Mill Test Report (MTR) or third-party lab certification.
Q: Can copper ingots be recycled?
A: Yes, copper is 100% recyclable without losing quality.
Q: What’s the average lead time for orders from China?
A: Typically 15–30 days, depending on quantity and shipping method.
Q: Are there alternatives to copper ingots?
A: Aluminum or brass ingots may substitute in some cases but lack copper’s conductivity.
