Mechanical Properties of A260 Brass

Yield Strength of A260 Brass

A260 Brass has a yield strength of approximately 120 MPa (17,400 psi), which provides a good balance between strength and flexibility. This property is crucial for applications where the material needs to withstand considerable stress without permanent deformation.

Tensile Strength of A260 Brass

The tensile strength of A260 Brass is around 330 MPa (47,900 psi). This indicates the maximum amount of stress the material can endure before breaking, making it suitable for high-stress applications.

Hardness Rockwell of A260 Brass

A260 Brass typically exhibits a Rockwell hardness ranging from 55 to 65 on the B scale. This hardness level ensures that the material is durable and resistant to wear, yet still machinable for precise manufacturing processes.

Fatigue Strength of A260 Brass

A260 Brass exhibits good fatigue strength, meaning it can withstand repeated stress cycles without failing. This property is essential for components that experience continual loading and unloading, such as mechanical and structural parts.


Machinability of A260 Brass

Machinability Rating of A260 Brass

A260 Brass has a high machinability rating, often around 100%, which is considered excellent. This high rating means the alloy can be easily and efficiently machined, reducing production time and costs. 

The material's ability to be precisely shaped makes it ideal for complex components and intricate designs. However, it may not be the best option for welding; and in its half-hard state, doesn’t have a good machinability.
