Harris 0 Brazing Alloy HARRIS

Harris 0 is a cost-effective brazing alloy primarily developed for copper-to-copper connections. It flows quickly at brazing temperature, making it suitable for tight joint tolerances typically below 0.005 inch. Because of its performance and economy, it is commonly selected for copper brazing operations.

The alloy can also be used for brazing brass components, although operators should carefully control heat input and apply Harris Stay Silv® white brazing flux to ensure proper results. Harris 0 is widely used in HVAC and refrigeration installations where reliable copper joints are required.

This alloy is not recommended for steel or other ferrous metals because phosphorus in the alloy can form brittle compounds with ferrous base materials.

FAQs

Is Harris 0 self-fluxing on copper joints?
Yes, phosphorus content allows self-fluxing on copper-to-copper connections.

Can it be used on brass?
Yes, but proper heat control and use of Stay Silv® white brazing flux are recommended.

Can it be used on steel?
No, it is not recommended for ferrous metals due to brittle compound formation.

Why is tight joint clearance important?
The alloy flows quickly and performs best in close-fitting joints.
