Brass bars / Alloys

Product catalog summary

Overview: The document provides detailed specifications for various copper-zinc-lead alloys, commonly known as brass, used in manufacturing. These alloys are categorized into different groups based on their machinability and suitability for cold forming.

Group A Alloys: These alloys, such as CuZn36Pb3 (CW603N) and CuZn38Pb4 (CW609N), offer excellent machinability but have limited cold forming capabilities. They contain a significant amount of lead, enhancing their machinability.

Group B Alloys: Alloys like CuZn37Pb2 (CW606N) and CuZn38Pb2 (CW608N) provide good machinability and better cold forming aptitude compared to Group A. They have slightly lower lead content.

Group C Alloys: These alloys, including CuZn35Pb1 (CW600N) and CuZn35Pb2 (CW601N), are both machinable and highly suitable for cold forming, with lower lead content than Group A.

Group D Alloys: CuZn36Pb2As (CW602N) is resistant to dezincification, maintaining good machinability and cold forming properties. It includes arsenic to enhance corrosion resistance.

Group E Alloys: Alloys such as CuZn39Pb2Sna (CW613Na) and CuZn40Pb2Sna (CW619Na) exhibit good machinability but limited cold forming ability. They are not suitable for high-speed machining and will be phased out by 2000.

Copper-Zinc Alloys Complex: This section details complex alloys like CuZn36Pb2Sn1 (CW711R) and CuZn37Mn3Al2PbSi (CW713R), which include additional elements like tin, manganese, and silicon to enhance specific properties such as strength and corrosion resistance.

Key Parameters: The document specifies the composition range for each element in the alloys, along with their approximate density, which is crucial for selecting the appropriate material for specific applications.
