Brass Capillary Tube Grades & International Equivalents

Shenzhen Chinalcometal Brass Capillary Tube Advantages:

1. Small Diameter and Thin Wall

Our brass capillary tubing can be supplied with outside diameters starting from 0.8 mm and wall thicknesses from 0.08 mm, making it suitable for precision components and compact assemblies.

2. Excellent Machinability

Brass is widely used for precision components because many brass grades offer excellent machinability, allowing the tube to be cut, drilled, formed, swaged or machined efficiently.

3. Good Corrosion Resistance

Brass provides good resistance to atmospheric corrosion and is suitable for many plumbing, sanitary, decorative and industrial environments.

4. Good Thermal and Electrical Conductivity

Brass offers useful electrical and thermal conductivity, making selected grades suitable for electrical terminals, heat-transfer components and other conductive applications.

5. Multiple Shapes

In addition to conventional round brass tubing, we can supply:

· Round brass tube

· Oval brass tube

· Square brass tube

· Rectangular brass tube

· Hexagonal brass tube

· Special/custom-shaped brass tube

6. Customized Dimensions

Custom brass capillary tubes can be produced according to customer drawings, OD, ID, wall thickness, length, shape and dimensional requirements.

Brass Capillary Tube Applications
