How to Distinguish Different Types of Brass

Common Types of Brass

Brass can be classified into several different types, the main ones including C22000, C26000, C28000, C36000, C44300, and C46400. These types are described in detail below.

1. C22000

C22000 is a brass with excellent weldability, corrosion resistance, and toughness. Its primary components are copper and zinc, with approximately 0.1% lead. It is commonly used in various decorative and ornamental parts.

2. C26000

C26000 is a copper alloy with a higher hardness. Unlike C22000, C26000 does not contain lead. Instead, it contains small amounts of manganese and iron, and a controlled copper-to-zinc ratio, resulting in improved corrosion resistance. C26000 is commonly used in the manufacture of metal pipes, electrical components, and decorative parts.

3. C28000

C28000 is a zinc-containing copper alloy similar to C26000, but with a higher copper content and a lower hardness. C28000 is commonly used in the manufacture of sheet metal, some tableware and utensils, and electrical wiring.

4. C36000

C36000 is a commonly used free-cutting brass material with a high lead content and good mechanical properties, making it particularly suitable for machining on automatic lathes. C36000 is commonly used in the manufacture of various mechanical parts, such as pipes, valves, and hardware.

5. C44300

C44300 is a copper alloy with a high copper content and a low aluminum content. It offers excellent corrosion and wear resistance and is commonly used in the manufacture of seawater valves and pressurized steam heaters.

6. C46400

C46400 is a lead-containing copper alloy with a lower hardness, good workability, and toughness. It is commonly used in the manufacture of ships, automobiles, construction, and chemical equipment.

Brass is difficult to accurately distinguish based on appearance, so we need to identify it based on its chemical composition and specific uses.

1. Chemical Composition: Using chemical analysis methods to analyze brass can reveal its detailed chemical composition, enabling accurate differentiation.

2. Applications: Different types of brass have different uses, and understanding their specific uses is also helpful in distinguishing between different brass types.

3. Qualification Certificates: When purchasing brass, it is important to see the manufacturer's relevant certifications to understand the specific brass type.

In short, by comprehensively identifying brass based on its appearance, chemical composition, uses, and relevant certifications, we can accurately distinguish different types of brass, thereby better understanding and using brass materials.

why choose us

Professional copper pipe supplier

As a professional enterprise dedicated to global copper product trade since 2008, GNEE Metal Group deeply recognizes the quality and responsibility embodied in the ASTM B111 standard. This standard not only specifies chemical composition and mechanical properties but also represents a comprehensive quality commitment spanning manufacturing processes to testing and verification. GNEE solemnly assures global customers that every ASTM B111-standard condenser tube and copper alloy tubing we supply will strictly adhere to its requirements for seamless manufacturing, annealing treatment, eddy current testing, and various mechanical performance tests.

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.
