焊接消耗品.銅和銅合金熔焊用實心焊絲和焊棒.分類The researching result is shown that an electron divided equally trend and an action of bond forming exist in brass atom and zinc atom in brass substtate. so, the electro - negativity equilibrium principle developed by sanderson et al, may be extend to the system such as brass under different conditions. the electro - negativity equilibrium was produced during the process from pure brass and pure zinc to brass - zinc alloy, and the difference of chemical properties between alloy and pure material is great
結果顯示黃銅中銅鋅原子間存在一定的電子「均分」趨勢，使銅鋅原子間存在一定的成鍵作用，可以將sanderson等人提出的「電負性均衡原理」有條件地推廣到黃銅這類合金體系中，正是這種銅鋅形成合金時所產生的電負性均衡，使得黃銅中的銅鋅與單質狀態下的銅鋅相比，在化學性質上發生了差異，且增強了黃銅的穩定性，限制了黃銅中的鋅在鍍液中滲出。Manufacturing processes joining - part 7 : joining by soldering or brazing ; classification, subdivision, terms and definitions
