藥芯鋁焊絲性能優勢

發布日期:2019-01-16 16:16
藥芯鋁焊絲性能優勢:
1、E8812NC流動性極好, 釬縫光亮細膩,熔點低(577℃-582℃),耐腐蝕性好;
2、操作方便,無須蘸焊劑,操作場地清潔,工件更清潔;
3、可操作性更好,對操作人員技術要求低;
4、釬劑為無腐蝕釬劑,產品符合ROHS;
5、釬劑填充均勻,無斷粉空心現象,不漏粉,焊接產品焊口合格率高;
6、手工焊絲配無腐蝕釬劑,焊藥蘸不均勻,焊接溫度高易導致鋁材過燒,釬劑焊絲填充消耗量大,焊口不光滑美觀,釬劑釬料過多流入管內堵管影響冷媒流量,釬劑流入過多成屑易堵塞管路;
7、手工焊絲配有腐蝕釬劑QJ201/0726等氯化物釬劑,釬劑焊接熔點雖低,但清洗不環保,殘留氯化物釬劑易腐蝕管子導致破壞;
