C110 Copper
C110 copper is also known as "electrolytic tough pitch" or ETP copper. It has a minimum conductivity rating of 100% IACS (International Annealed Copper Standard). This makes it popular in applications where electrical conductivity is paramount, such as electrical wiring and connectors. It also has high ductility, making it easy to shape into any desired form.
C11000 Copper
C11000 copper is also known as "electrolytic-grade oxygen-free" or OFE copper. It has a higher conductivity rating than C110 (101% IACS) and typically contains trace amounts of oxygen that give it greater strength than ETP copper. This makes it popular in applications where strength is important, such as plumbing fixtures and heat exchangers. It also has good ductility but not quite as good as ETP copper.
Difference Between Copper C110 and C11000
Copper C110 (also known as Electrolytic Tough Pitch or ETP) is a high purity copper that contains 99.90% copper and is ideal for electrical applications where the highest levels of conductivity are required. Copper C11000 (also known as Oxygen Free Electronic or OFE) is a lower purity copper that contains 99.99% copper and is ideal for applications where the highest levels of conductivity are not required.
Composition
Copper C110 contains 99.90% copper, 0.04% oxygen, 0.03% iron, 0.02% sulfur, and 0.01% phosphorus. Copper C11000 contains 99.99% copper, 0.002% oxygen, 0.001% iron, and 0.0005% sulfur.
Electrical Conductivity
Copper C110 has a conductivity of 100%, while copper C11000 has a conductivity of 97%. This means that copper C110 is the better conductor of electricity between the two types of copper.
Thermal Conductivity
Copper C110 has a thermal conductivity of 401 W/mK, while copper C11000 has a thermal conductivity of 401 W/mK. This means that both types of copper are equally good at conducting heat.
Price
Copper C110 is typically more expensive than copper C11000 because it is a higher purity metal and has better electrical conductivity. However, the price difference between the two types of copper can vary depending on the market conditions at any given time.
