    Product Introduction

    The most commonly used aluminum grades for aluminum capillary tubing are 1050, 1060, 1070, and 3003. Aluminum capillary tubing is available in wall thicknesses ranging from 0.2 mm to 2.5 mm.
    Aluminum capillary tubing is available in a variety of finishes for your convenience. Standard finishes include anodized, polished, powder-coated, and sandblasted. Choose the finish that best suits your business needs!

    Key Advantages (Bullet Points)

    Lightweight Design: 

    Aluminum's density is only one-third that of copper, significantly reducing overall system weight and making it an ideal choice for new energy vehicles, portable devices, and aerospace microsystems.

    Excellent Machinability and Flexibility:

    Aluminum capillaries offer excellent formability and bendability, making them compatible with a variety of connection methods and automated assembly processes.

    Guaranteed Corrosion Resistance:

    Aluminum easily forms a dense oxide film on its surface, effectively resisting corrosion in dry environments or neutral media.

    Excellent Thermal Conductivity:   Aluminum's excellent thermal conductivity, combined with its lightweight advantages, results in superior overall thermal efficiency.
