What is C10200?

What is C10200?

C10200 – also known as oxygen-free (OF). While OF is considered oxygen-free, its conductivity rating is no better than the more common ETP grade below. It has a 0.001% oxygen content, 99.95% purity and minimum 100% IACS conductivity. ETP has a minimum conductivity rating of 100% IACS and is required to be 99.9% pure.

What is oxygen-free copper used for?

Oxygen-free copper is used for industrial applications, such as for the windings in large electrical generators where the wire is constantly exposed to high temperatures and vibration, as well as for audio and video cabling, where the increased conductivity is believed to improve low-frequency transmission.

What is IACS conductivity?

IACS is the abbreviation for International Annealed Copper Standard and the number preceding “IACS” is the percentage of conductivity a material has relative to copper, which is considered to be 100% conductive. This standard refers to a pure, “standard” copper having a resistivity of 1.7241 microhm-cm at 20°C (68°F).

What kind of material is OFHC copper?

Overview of OFHC Copper Oxygen-free, high-conductivity (OFHC) copper—sometimes referred to as simply oxygen-free copper—is a copper material that has undergone electrolytic refinement to reduce the oxygen contained within it to very low levels (typically less than 1/100 of a percent).

Does oxygen-free copper make a difference?

According to tests, oxygen-free copper also runs cooler than other conductors. It’s more resistant to shorts, more durable and long-lasting, and is far less likely to corrode, due to the reduced oxygen content—at least, that’s the common wisdom.

What is tough pitch copper used for?

It is extensively used in electric power systems, electrical installations in homes, offices and industry and all kinds of electrical and electronic equipment. ETP1 is the highest purity tough pitch copper with a maximum impurity content of 0.0065% (compared to ETP with a maximum of 0.0355).

Why is oxygen-free copper used for high conductivity?

The high conductivity, high purity and low volatility under high vacuum make it ideal for this use because it is not subject to outgassing (release of trapped gas such as oxygen). Tough pitch copper is unsuitable for this application since it is less pure and might outgas under high vacuum.

What is copper oxygen free wire?

Oxygen free copper is a type of copper that has been refined in an electrically charged solution of copper sulfate and sulfuric acid. Some manufacturers also state that oxygen free copper wiring provides better clarity of sound, and lasts longer than other, less pure, copper wires.

What is IACS value?

The International Annealed Copper Standard (IACS) is a standard established in 1914 by the United States Department of Commerce. It is an empirically derived standard value for the electrical conductivity of commercially available copper.

How do you calculate %IACS?

IACS % = (172.41/resistivity) where resistivity, ρ,(ro) is in micro-ohms per centimeter.

What grade is OFHC copper?

OFE (Oxygen-Free Electronic) or OFHC (Oxygen-Free High Thermal Conductivity) Copper is the highest purity grade of copper at 99.99%.

What does annealed copper mean?

Annealed copper is obtained after hardening by subjecting it to a heat treatment to restore its malleability. Annealed copper is used in heating and plumbing works requiring tubes that are sufficiently flexible to be bent without requiring special tools.
