    H80N, I tried sending you a pm from my phone, but can't figure it out. I frequent Haun in Endicott NY once in a while. Are you from that area bud?

    Somebody in another thread had suggested 2319 filler for dirty aluminum castings... wonder where that fits in?? any thoughts..

    http://www.aircraftmaterials.com/data/weld/2319.html

    2319 is listed as an alloy that wants post weld heat treat...

    I am interested but puzzled??

    Are you saying 4943 will replace 4043 in all or most applications? Do you see any downside?

    Sure does look like it...

    I think Terry (Shovelon) has the most experience with it around here and he is pretty positive on it...

    My experience is much less... but all good...

    Thumbs up

    Am going to try and get somebody from Hobart/Maxal to chime in on 4943 and maybe give us some more in depth info...

    It is a propriatery alloy and relatively new...they are the only ones that have it...

    I don't see any downside whatsoever. My biggest concern was it's ability to take chem film. The latest job I did got chem film, and it took it fine. 5356 does not take chem film well.

    As far as strength, I can really tell the improvement. It is less gummy for threading like 4043 is but I still prefer the 5356 as I have used it for years.

    What gets me is how fast 4943 wets. I barely strike an arc to the root, add filler and whammy I am off. More forgiving than 5356 on castings.

    What I don't like is the price.

    It's good to see that there is interest in the 4943 alloy on the Miller forum.

    Let me introduce myself...I am the Senior Welding Engineer for Hobart Aluminum (formerly Maxal) and am the Product Specialist for the eastern half of the US. I have been with the ITW Welding Group since 1998 and was a Welding Engineer for Miller Electric in Appleton, WI for 5-1/2 years and worked on several of the Millermatic products (MM 210, MM 251, MM350P to name a few). Prior to coming to Maxal I was the Welding Engineer at the ITW Corporate Welding Technology Center in Chicago. Please feel free to contact me via email if you ever have aluminum welding related questions.

    Here are the updated datasheets for all the aluminum alloys offered by Hobart Aluminum:

    Maxal 1100
    Maxal 4043
    Maxal 4047
    Maxal 4943
    Maxal 5183
    Maxal 5356
    Maxal 5554
    Maxal 5556

    Also, here is the 4943 Article in AWS Welding Journal from the July 2013 issue.

    I will attempt to answer some of the open questions:

    "Are you saying 4943 will replace 4043 in all or most applications? Do you see any downside?"
    Yes, 4943 can be used as a replacement anywhere 4043 is currently being used. In the as welded condition it will produce 50% higher yield strength and 25% higher UTS. 4043 as welded tensile strength is 28 ksi and 4943 is 35 ksi.

    Due to its chemistry it is also heat treatable (4043 is not) so if you need higher strengths it can be post weld age and achieve 42 ksi (same strength as 6061-T6) and even higher strength can be achieved if you PWHT&A (49 ksi).


    Is 4943 gummy like 4043...or can it be machined and threaded like 5356...just curious if anybody has experience on that aspect..
    You might notice that 4943 is slightly less gummy than 4043 but not appreciably. 5356 is 'harder' due to the 5% Mg in it's chemistry whereas 4943 is 5% silicon and 0.4% Mg.

    Price is higher

    Yes, the price is slightly higher but we have no control over what our distributors charge. If you don't like the price your distributor is charging, check with another distributor in your area--they might sell it for less. Because its a new alloy, they might be charging more up front because they may feel that there is some level of 'risk' in stocking this alloy. Here is a link to find Hobart Distributors. As more people start requesting 4943 the distributors will begin stocking it regularly and this might cause the price to drop some.

    Regards,
    Galen
