使用說明Operation Introduction
銅磷釬料是以銅、磷兩元合金和銅、磷、銀三元合金為基的釬料，它具有良好的流動性，適用于接觸釬焊、氣體火焰釬焊、高頻釬焊及爐中釬焊。銅磷合金中加入銀會大大地提高焊料濕潤能力，提高強度和韌性，降低熔點。廣泛應用于電冰箱、空調器等制冷行業，以及電機、電器、儀器等制造行業。
銅磷釬料適宜于釬焊銅及黃銅，但是不適宜釬焊黑色金屬。釬料中的磷可以還原氧化銅及氧化銀，起著釬劑作用，因此銅磷釬料釬焊銅和銀時，可以不需要釬劑，但在釬焊銅合金時，因為磷不能充分地還原銅的合金元素形成的氧化物，為了獲得優質釬縫，還應與釬劑配合使用。

The copper-phosphorus filler metals with good fluidity are a kind of copper and phosphorus two elements alloy base or copper,phosphorus and sliver three elements.They can adopt contact welding.oxyfuel gas welding.high frequency welding and furnace welding. The copper-phosphorus alloy with sliver will greatly improve wettability,strength toughness and lower melting point.theseproducts are mainly applied on the refrigeration.air conditioner.water heater as well as transformer,motor,instruments and meters etc. Thecopper-phosphorus filler metals are suitable to braze copper,brasses but they can not be suitable to braze ferrous.The phosphorus in the filler metals can reduce oxide of copper and oxde of sliver as braxing flux,so you don`t need it when you braze when you braze copper alloy because the phosphorus can`t fully reduce the oxide formed by copper alloy element. Before brazing,you should clear away all dirt on the brazed place and on the surface of object to be brazed such as greasy dirt,oxide and so on,the best brazed joints is between0.03mm to 0.075mm. Theheat speed should be quick as possible when brazing in order to avoid the flat of the filler metals because of slow heat process .The copper color will be reture if it is dipped into 10percent of sulphuric acid solution.

釬焊前必須嚴格清除釬焊金屬表面的油脂、氧化物等污物，釬燭接頭的最好間隙為0.03~0.075mm。釬焊時加熱速度盡可能快些，避免因加熱過程緩慢造成銅磷釬料偏析，焊后的顏色是亮灰色，浸在10﹪硫酸中將恢復銅的顏色。
