Brand Name: Global
Model Number: BCuP-2(Brazing wire)
Place of Origin: Zhejiang, China (Mainland)
Material: Copper / Copper Alloy
Diameter: 2.0mm, 2.5mm, 3.2mm
Application: for welding
Have good wetting ability, good mechanical strength and toughness with low melting point
Phos-Copper-silver brazing alloys have good wettability, higher strength and toughness of brazing seam and lower melting point. The heating speed should be as quick as possible while brazing. The joint is to be bright grey and will return to the original color of bronze while dipped into 10% sulphuric acid.
