H63 is a type of copper alloy commonly referred to in China and some other regions. It is equivalent to the international standard of C27200, which is known as "Yellow Brass" in the United States. Here are the typical composition ranges for H63 (C27200) copper alloy:

H63 copper wire refers to a specific alloy that is commonly referred to in China and parts of Asia. It is equivalent to the international standard C27200, which is known as "Yellow Brass" in the United States. Here are the typical chemical compositions for H63 (C27200) copper alloy:

Copper (Cu): Approximately 65%

Zinc (Zn): Approximately 35%

The composition of H63 (C27200) consists primarily of copper and zinc, with zinc being the major alloying element. This combination gives H63 its characteristic yellow-gold color and specific properties.

Other Elements:

Lead (Pb): Up to 0.05% (typically low or absent)

Iron (Fe): Up to 0.1%

Tin (Sn): Up to 0.3%

Phosphorus (P): Up to 0.1%

Other elements: Small amounts of other elements may be present as impurities or intentional additions to adjust specific properties.

Features and Characteristics of H63 (C27200) Copper Wire:

Color and Appearance: H63 (C27200) has a distinctive yellow-gold color due to its higher zinc content, which makes it visually different from pure copper.

Machinability: It has good machinability, allowing it to be easily shaped, drilled, and fabricated into various components and parts.

Corrosion Resistance: H63 (C27200) offers good resistance to atmospheric corrosion and certain types of chemical corrosion. However, it may not be as resistant to corrosion in marine or highly acidic environments compared to other copper alloys.

Electrical Conductivity: While not as conductive as pure copper, H63 (C27200) still retains reasonable electrical conductivity, making it suitable for electrical connectors and terminals where moderate conductivity is sufficient.
