Copper and Copper Alloy Capillary

High-precision copper capillary

Oxygen-free copper is one of the most common metal materials with good plasticity and is widely used in industrial fields. At present, our company mainly manufactures high-precision oxygen-free copper capillary tubes, and the accuracy can reach the “micron level”. Our company has outstanding advantages in the manufacture of commonly used material capillary tubes. At present, we mainly produce the following types of capillaries:

  1. High precision requirements (within ±0.01mm);
  2. Very fine outer diameter (within 0.2-1.2mm outer diameter);
  3. Very thin wall (T<0.06mm);
  4. Very thick wall (outer diameter: inner diameter>2:1)


High-precision beryllium copper alloy capillary

     Beryllium copper and Monel 400 are two kinds of copper-nickel alloys, which have good elasticity and excellent corrosion resistance. They are one of the special copper alloy metal materials and are widely used in industrial fields.


Specifications for our Copper, Beryllium copper, and Monel 400 alloy Capillary:

Size specifications: outer diameter Φ0.2~Φ8mm, wall thickness: T0.015~0.5mm.

Highest precision: outer diameter: Φ±0.003mm, wall thickness: T±0.005mm, length: L±0.03mm.

Appearance: Observed under a microscope, the inner and outer surfaces of the tube show a uniform metallic luster, without oxidation, hydrogenation, discoloration, scratches, deformation, burrs, etc.

Specifications can be customized according to user requirements based on the above range.
