Copper phosphorus brazig alloy welding rod

INTRODUCTION

sCopper 0 is primarily used for the joining of copper-to-copper on vibration free joints.

It is very effective for joining tight fitting copper pipe and tubing and is used extensively in the Heating, Ventilating and Air Conditioning (HVAC) industry to make preform rings for evaporators/condensers.

sCopper 0 should not be used on ferrous metals or copper alloys containing more than 10% nickel because of srus embrittlement due to reactions with iron or nickel.

sCopper 0 is extremely fluid at brazing temperatures and will penetrate joints with very little clearance.

Best results are obtained with clearances of 0.001-0.003".

Melting of sCopper 0 is virtually complete at 1350°F (732°C).

Best results are obtained when brazing slightly above this temperature.

CHARACTERISTICS

Brazing copper and copper alloys, as well as brass, bronze, silver, tungsten and molybdenum.

PROPERTIES OF BRAZED JOINTS

Generally, the joint strength produced by sCopper 0 will surpass the strengths of the base metals.

Strength is a function of the base metals being joined, type of joint, design of joint, joint clearances and brazing procedures.

The recommended maximum operating temperatures for sCopper 0 are 300°F (continuous service) and 400°F (intermittent service).

Corrosion resistance is satisfactory except when the joint is in with sulfurous atmosre (especially at elevated temperatures).

ADDITIONAL INFORMATION

The srus content of sCopper 0 acts as fluxing agent and no flux is necessary when brazing copper joints.

However, when used with a copper alloy or one of the other brazeable metals, White Silver Flux must be used to promote wetting, bonding, and flow throughout the joint.

The flow point of sCopper 0 is 1350°F (732°C)
