Note: All sizes are standard, other sizes can be produced according to customer requirements.
Standard export seaworthy packing: with polyethylene film including drier, put them in carton; 5.67kgs/pvc bag, 11.34kgs/carton box;or 5kgs/pvc bag, 10kgs/carton box;
A1: These alloys are composed of Copper (Cu) and Phosphorus (P).
A2: No extra flux is required. When brazing copper with this copper-phosphorus alloy, the phosphorus content within the alloy itself plays the role of the brazing flux.
A3: They are widely used for HVAC, plumbing, and mechanical repairs. They are suitable for brazing copper and copper alloys in motor, instrumentation, and refrigeration industries, including air conditioners, freezers, evaporators, heat exchangers, and water heaters.
A4: The standard sizes include Flat (1.3x3.2x457mm / 1.3x3.2x500mm), Square (3.2x3.2x500mm), and Round (1.5x500mm / 2.0x500mm / 3.0x500mm).
A5: Yes. While standard sizes are readily available, other custom sizes can be produced according to specific customer requirements.
A6: The standard export seaworthy packing includes a polyethylene film with a drier inside. It is packed either as 5.67kgs/pvc bag (11.34kgs/carton box) or 5kgs/pvc bag (10kgs/carton box).
