Home > Alloy 20 Tube Fittings
Nestled in Hamilton, New Zealand, Mason Tubefittings stands as a trusted partner for industry, specializing in the manufacture and supply of high-performance Alloy 20 tube fittings.

Our local presence means you get the dual benefit of world-class materials backed by responsive, personalized service, ensuring your projects in challenging environments are supported by fittings built to last.
The strength of our Alloy 20 fittings comes from their carefully balanced composition, which includes significant nickel, chromium, and copper, along with the strategic addition of molybdenum and columbium. This specific recipe gives the alloy outstanding resistance to corrosion, particularly against sulfuric acid and chloride stress corrosion cracking. Beyond its chemical resilience, the material provides excellent mechanical properties, including high tensile strength and good ductility, allowing these fittings to maintain their integrity and form under significant pressure and stress.
