TP1 copper bar, according to Chinese standard GB/T 8890-2018, has a specific chemical composition that defines its high purity and suitability for various applications. Here are the typical chemical components of TP1 copper:

Copper (Cu): The primary component of TP1 copper is copper itself, with a minimum purity of 99.95%. This high copper content ensures excellent electrical and thermal conductivity.

Other Elements: TP1 copper may contain trace amounts of other elements, but they are typically kept to a minimum to maintain the high purity required for its intended applications. These trace elements can include:

o Oxygen (O): Typically, the oxygen content is very low, less than 0.05%.

o Phosphorus (P): Often present in small amounts to enhance the material's mechanical properties.

o Sulfur (S), Iron (Fe), Lead (Pb), and other impurities: These are usually present in trace amounts, but their concentrations are tightly controlled to ensure the copper maintains its high conductivity and purity standards.

Key points about the chemical composition:

High Copper Content: TP1 copper is distinguished by its high copper content, which is essential for achieving excellent electrical conductivity.

Low Oxygen Content: The oxygen content in TP1 copper is controlled to be very low, typically less than 0.05%. This low oxygen level helps maintain high electrical and thermal conductivity by minimizing the formation of copper oxides, which can impair conductivity.

Minimal Impurities: TP1 copper is characterized by its low levels of impurities such as sulfur, iron, and lead. These impurities are kept to a minimum to ensure the copper meets stringent purity requirements and performs effectively in various applications.
