Types of Copper Strips
1. Electrolytic Tough Pitch (ETP) Copper Strips
Electrolytic tough pitch copper, often referred to as ETP, is the most common type of copper used for electrical applications. It is known for its high conductivity (minimum of 101% IACS) and is widely used in electrical circuits and connectors. ETP copper strips are favored for their excellent workability and solderability, making them ideal for various electrical components.
2. Oxygen-Free Copper (OFC) Strips
Oxygen-free copper strips are composed of 99.99% pure copper with minimal oxygen content, enhancing their ductility and resistance to hydrogen embrittlement. These strips are commonly used in high-current applications, such as audio equipment and specialized electronics, where superior conductivity and reliability are critical.
3. Copper Alloy Strips
Copper alloy strips are created by combining copper with other metals, providing enhanced properties such as increased strength and corrosion resistance. These strips are often used in decorative applications and architectural fixtures, making them a popular choice among artisans and manufacturers.
4. Copper Foil
Copper foil is a thin sheet of copper that can be used in various applications, including PCB manufacturing and crafts. It is available in varying thicknesses and is ideal for detailed work, such as intricate designs in electronics and decorative art projects.
5. Copper Flashing
Copper flashing is thicker and is primarily used in roofing and weatherproofing applications. Its durability and resistance to corrosion make it an excellent choice for protecting structures from the elements while providing an aesthetically pleasing finish.
6. Copper Strips for Crafts
These copper strips are designed specifically for hobbyists and crafters. They come in various thicknesses and sizes, making them suitable for model making, jewelry, and other creative projects. Their flexibility and ease of use make them a favorite among DIY enthusiasts.
