Brass tubing is graded according to the ratio of copper to zinc, primarily including C21000, C22000, C23000, and C26000.
Brass Tubing Grades and Performance Characteristics
Brass tubing is a well-balanced alloy material with excellent electrical conductivity, corrosion resistance, and heat resistance. It is widely used in aerospace, machinery manufacturing, architectural decoration, and chemical industries. Brass tubing can be classified into several grades based on the copper-zinc ratios within the tubing. The main grades are as follows:
1. C21000: Contains a pure copper content exceeding 95.0%, suitable for the specialized requirements of high-tech fields such as electronics, aviation, and aerospace.
2. C22000: This is the most widely used brass tubing in industry. Its copper content ranges from 90% to 94% and its zinc content is approximately 5%. It possesses excellent impact strength and toughness, and is widely used in machinery manufacturing, architectural decoration, and other fields.
3. C23000: Contains 10-16% zinc, offers excellent wear and corrosion resistance and is commonly used in the manufacture of wear-resistant components such as transmission bearings and door and window hardware.
4. C26000: Contains 30-35% zinc, boasts high strength, good ductility, and excellent wear and corrosion resistance. It is widely used in machinery manufacturing, architectural decoration, and chemical industries.
Main International Grades and Applications of Brass Tubes
In the international market, brass tube grades vary according to national standards and intended uses. Commonly used grades include H62, H65, and H68. Among them, H62 has a copper content between 60% and 63%, offering excellent corrosion resistance and is commonly used in home decoration and appliance component manufacturing. H65, with a copper content between 63% and 68%, offers excellent strength and wear resistance and is commonly used in the chemical and mining industries. H68, with a copper content between 67% and 71%, offers even higher strength and is often used in the manufacture of surface coatings for steel products.
In general, brass tube grades and applications are categorized based on the ratio of copper to zinc content. Choosing the appropriate brass tube material based on the characteristics and performance of each grade can meet the needs of different applications.

Packaging and shipping
GNEE offers professional packaging for exported copper pipes. First, we apply anti-rust oil and plastic film to prevent oxidation. Then, we securely strap with steel straps and add corner protectors. Finally, we place the pipes on wooden pallets and reinforce them with iron or wooden boxes, ensuring they are moisture-proof and impact-resistant during ocean transport, while facilitating easy loading and unloading. All packaging meets export standards.
