由于鍍鋅鋁鎂鋼板的鍍層比其他熱浸鍍鋅鋼板及熱浸鍍鋅鋁鋼板更堅硬，具有更優異的耐刮痕性，可適用于加工時易出現刮痕或反復受到摩擦或

磨損的部位。鍍鋅鋁鎂鋼板同其他鍍鋅類鋼板一樣，易受低熔點金屬鍍層的影響。在電弧電焊中，與熱軋、冷軋鋼板相比，容易出現飛濺和氣孔

的增加以及由于裂紋而造成強度下降等。但是，如果條件選擇適當，焊接接縫就不會存在連接強度的問題。而且，在電焊中，只要選定恰當的

焊接條件，強度也豪無問題。另外，在電焊過程中，也會受到焊機和接縫形狀等的影響，因此請事先通過焊接測試加以確認。佛山萬慶物資認為

“鍍鋁鋅鎂鋼卷”的耐腐蝕性主要是因為鋁，鋁的保護功能。當鋅受到磨損時，鋁便形成一層致密的氧化鋁，阻止耐腐蝕性物質進一步的腐蝕內部。

Because the coating of galvanized aluminum magnesium steel plate is harder than other hot dip galvanized steel plate and hot dip galvanized aluminum

steel plate, with better scratch resistance, can be applied to processing prone to scratch or repeated friction or wear parts.Galvanized aluminum and magnesium

steel plate, like other galvanized steel plate, is susceptible to low melting point metal plating.In arc welding, compared with hot rolled and cold rolled steel plates,

it is easy to increase in splash and pores and cause strength decline due to cracks.However, if the conditions are chosen properly, there will be no connection

strength problem of the welding joints.Moreover, in electric welding, as long as the appropriate welding conditions are selected, the strength is also no problem.

In addition, in the welding process, will also be affected by the welding machine and joint shape, so please confirm through the welding test in advance.

Foshan Wanqing Materials believes that the corrosion resistance of "aluminum-coated galvanized magnesium steel coil" is mainly due to the protection

function of aluminum and aluminum.When zinc is worn, aluminum forms a dense layer of alumina, preventing further corrosion of the interior.
