A comprehensive guide to brass tubing: H62, H65, H68, and other models
What is brass?
Brass is an alloy primarily composed of copper and zinc; different proportions of copper and zinc result in different grades and properties. Brass typically has a density between 8.4 and 8.7 g/cm³, making it a lightweight yet strong material. The specific grade of brass significantly affects its properties, such as corrosion resistance, machinability, and strength.
Understanding Brass Grades
- H62 Brass Pipe: This grade of brass contains approximately 62% copper and is renowned for its excellent corrosion resistance and good mechanical properties. It is commonly used in piping and electrical applications.
- H65 Brass Tubes:H65 brass tubes have a higher copper content, approximately 65%, resulting in greater strength and ductility. They are commonly used in applications requiring high wear resistance.
- H68 Brass Tubes: This grade has a higher copper content, approximately 68%, and offers excellent corrosion resistance, making it ideal for marine applications.
- C2680, C2700, and C2800 Brass Pipes: These are standard grades of brass alloys containing different proportions of copper and zinc. C2680 is commonly used for pipe fittings, while C2700 and C2800 are more popular due to their superior machinability and strength.

Brass pipes and copper pipes
Several factors need to be considered when comparing brass and copper tubing. Brass tubing is generally more resistant to corrosion and abrasion, making it more suitable for humid and chemical environments. Furthermore, brass tubing is typically more economical than copper tubing, making it an economical choice for many projects.
Electrical Applications: Tin-plated Copper and Pure Copper
In electrical applications, the choice between tin-plated copper and pure copper depends on the specific requirements of the project. Tin-plated copper offers greater corrosion resistance, making it suitable for humid environments. However, pure copper boasts superior conductivity and is the preferred material for high-performance wires and cables.
Relevant dimensions of brass tubes
Brass tubing is available in various sizes to meet different application requirements. Commonly used sizes include:
- Outer diameter (OD):ranging from 1/8 inch to several inches.
- Wall thickness:typically between 0.020 inches and 0.125 inches.
- Length:The length can be customized according to project requirements.
Uses of brass tubing
Brass tubing is widely used in various fields, including:
- Pipes: Used for water supply pipes and fittings.
- Electrical:Used for wiring and connectors.
- Automotive industry:fuel lines and fittings.
- HVAC:Used in air conditioning and refrigeration systems.
- Marine:Suitable for components exposed to saltwater environments.
