    started a topic maxel 4943 aluminum filler wire

    maxel 4943 aluminum filler wire

    has any body been using the 4943 filler I am about to build an airboat hull with 1/8th 5052 aluminum sheet and will be using it on ice in Michigan I like the idea of it being stronger then the 4043 with same characteristics what would be the best filler for my project thanks

    Aluminum Filler selection involves weighing the importance of a number of factors and characteristics of the available filler metals...

    This video gives a quick overview..

    The strength of 4943 is close to that of 5356...Here is a comparison of tensile strength (fillet shear strength is approximately 60% of tensile strength)

    4043 = 28ksi
    5356 = 38ksi
    4943 = 35ksi

    Unlike steel, aluminum doesn't get brittle in cold temperatures. Actually, the strength and toughness increases in aluminum alloys as the temperature decreases. That said, 5356 does have better ductility and toughness (ability to withstand flexing and resist cracking under impact) than 4943 or any other 4xxx alloy.

    thanks for the reply my concern is more the strength and flex of the filler being that the project is a ice airboat lots of vibration

    Maybe this video will help to fill in some of the blanks..

    Tony Anderson, director of aluminum technology, ITW Welding North America, discusses 4943 the first new aluminum filler metal to be developed, registered by the Aluminum Association and classified by the American Welding Society in nearly five decades

    would also think that Galen will check in when he can...

    I had sent a note to Galen:

    Galen



    Could you give us some insight on how 4943 will behave in marine environments with 5052..??

    knowing that some fillers will oxidize to white powder under saltwater and other marine environments…



    He sent me a couple of quick notes back

    Heiti,

    I'm on the road right now and don't have access to my laptop and I can't reply to the post with my iphone for some reason. I'll try to get on tonight and reply. FYI 5052 and 4943 are very compatible as far as corrosion resistance goes. Actually most pontoons on pontoon boats are 5052 welded with 4043 and the hold up very well in both fresh and saltwater. ....

    Feel free to share my response with the forum. 4943's corrosion performance will be nearly identically to 4043 and would be given a 'B' rating when used to weld 5052. 5356 has an 'A' corrosion resistance rating when welding 5052 and will have a slightly better color match. .....



    Regards,

    Galen

    Have you read this thread on 4943..??

    Here is another thread.. this one about using 4943 filler on 5052..

    Am hoping Galen White of Hobart/Maxal can chime in and give us more insight on suitability in a marine environment..
