🔬 What is C11000 ETP Copper?

C11000 ETP (Electrolytic Tough Pitch) Copper is a high-conductivity copper alloy containing ≥99.90% copper and ≤0.04% oxygen. The oxygen improves the thermal stability of the copper matrix but slightly reduces hydrogen embrittlement resistance compared to OFHC (Oxygen-Free High Conductivity) copper.

This balance of purity, performance, and cost makes C11000 ETP Copper Rod the most economical and practical solution for electrical and thermal conductivity requirements.

❓ Frequently Asked Questions (FAQ)

Q1: What is the difference between C11000 and C10200?
A: C11000 contains oxygen and has slightly lower hydrogen embrittlement resistance but is more cost-effective than C10200 (OFHC copper).

Q2: Is C11000 copper suitable for welding?
A: Yes, it can be welded using gas or resistance welding techniques. For high-vacuum environments, consider OFHC alternatives.

Q3: Can I get custom-cut rods?
A: Absolutely. We support cut-to-length services with tolerances as tight as ±0.05 mm.

Q4: Do you provide export compliance support?
A: Yes. We provide CO, FTA, Form A/E/F, and other export certifications as needed.
