What is Annealed C10200 Copper Wire?
Our Annealed C10200 Copper Wire is engineered for precision and reliability. Known as Oxygen-Free (OF) copper, C10200 strikes the perfect balance between high conductivity and cost-effectiveness for advanced electrical engineering.
The "Annealing" process is what sets this wire apart. By carefully heating and cooling the copper, we achieve a soft, flexible temper that is ideal for intricate wiring, transformer windings, and coaxial cables. Unlike standard ETP copper, our C10200 wire contains no residual oxygen, meaning it won't become brittle or crack when exposed to hydrogen at high temperatures-a critical factor for vacuum technology and high-performance power electronics.
C10200 Annealed Copper Wire Material Properties
C10200 Annealed Copper Wire has excellent electrical conductivity of over 99%, which helps to reduce resistance and increase current transfer efficiency, making it ideal for high power current transfer.
The material also has excellent machinability, allowing it to be processed into a wide range of shapes and sizes, while its strength and corrosion resistance are high enough to maintain stable performance over time.
The annealing treatment gives C10200 copper wire better ductility and toughness and reduces hardness, making it easier to machine and form.

FAQ
Q1: What does "Annealed" mean for this copper wire?
A: Annealing is a heat treatment process that alters the physical properties of the copper. It makes the wire much softer and more ductile. This is essential for applications where the wire needs to be bent, coiled, or shaped without developing stress fractures or breaking.
Q2: Why should I choose C10200 (OF) instead of standard T2 (C11000) copper?
A: C10200 is Oxygen-Free. Standard T2 copper contains oxygen which can react with hydrogen at high temperatures (brazing/welding), leading to internal cracks (hydrogen embrittlement). If your project involves heating or high-reliability electrical paths, C10200 is much safer and more durable.
Q3: Is C10200 suitable for high-vacuum applications?
A: Yes, it is widely used in vacuum electronics. Because it is highly refined and oxygen-free, it has a very low vapor pressure and doesn't release trapped gases, ensuring the integrity of the vacuum environment.

Packaging of C10200 pure copper wire
To ensure your high-purity copper products reach you in pristine, oxide-free condition, we employ a multi-layered, export-grade packaging system: each spool or coil is first wrapped in anti-oxidation PE film and vacuum-sealed with desiccants to combat maritime humidity. For structural protection, products are secured within reinforced, shock-resistant wooden crates or heavy-duty pallets that comply with international shipping standards (ISPM 15), guaranteeing that the wire's conductivity and physical integrity remain compromised throughout global transit.
