瑞典伊萨ER1070铝合金焊丝
OK Autrod 1070 GMAW ER1070 OK Autrod 1070 is highly resistant to chemical attack and weathering. It is a relatively soft alloy that is very formable and it is used extensively in thin-gauge and foil products. It has good welding characteristics. One characteristic feature of the alloy is the bright finish obtained by anodising. Non-heat treatable.
