    Default motor plate aluminum

    I just found out from my metal supplier that the plate they sent for my front plate is 5052 not 6061 t6
    the plate is already cut drilled and ready to test fit into my boat.
    do I use the 5052 or recut it from 6061?

    they will replace it No Charge. Just out the labor and time
    cutting a new one.

    General Information


    Here is some info for you. details 5052 aluminum



    Principal Design Features

    This is a non-heat treatable alloy that is weldable. It is hardened by cold work. It has good forming characteristics and good corrosion resistance, including resistance to salt water.

    Applications

    Commonly used in the manufacture of hydraulic tubes, kitchen cabinets, small boats, home freezers, milk crates, aircraft tube, fencing, and appliances. Commonly used in sheet metal work and in sheet metal parts.

    Machinability

    This alloy has relatively fair machinability. It is easier to machine in the hard temper than as annealed and the quality of finish is better if machined in the hard condition. Oil lubricants should be used for machining, except that very light cuts may be done dry.

    Forming

    AL 5052 is readily formed at room temperature. Successive cold working decreases the formability.

    Welding

    This alloy is readily welded by conventional methods. When filler rod is required it should be aluminum alloy 5356 as filler. Either tungsten or consumable electrode inert gas shielded arc welding is preferred method.

    Heat Treatment

    AL 5052 cannot be hardened by means of heat treatment. It does harden due to cold working.

    Forging

    The alloy may be forged in the temperature range of 950 F down to 500 F.

    Hot Working

    Hot working, as with forging, may be done in the range of 950 F to 500 F.

    Cold Working

    The alloy cold works readily and may be formed by drawing or spinning. However the amount of cold work imparted by spinning makes intermediate annealing necessary.

    Annealing

    Anneal at 650 F and air cool.

    Aging

    Not applicable to this alloy.

    Tempering

    Not applicable.

    Hardening

    Hardens only from cold working.

    Other Physical Props

    Electrical conductivity 33% of copper.

    Other Mechanical Props

    Shear strength for O temper is 18 ksi. For cold worked temper H 34 it is 21 ksi.

    Here is the same info for 6061

    Principal Design Features Probably the most commonly available, heat treatable aluminum alloy.


    Applications Commonly used in the manufacture of heavy-duty structures requiring good corrosion resistance, truck and marine components, railroad cars, furniture, tank fittings, general structural and high pressure applications, wire products, and in pipelines.


    Machinability Machinability in the harder T 4 and T6 tempers is good. It is notably less easy to machine in the annealed temper.


    Forming Easily cold worked and formed in the annealed condition. Stamping, bending, spinning, deep drawing are all readily accomplished using standard methods.


    Welding The alloy has very good welding characteristics and may be welded by all of the common welding techniques. Gas tungsten arc welding is generally used for thin sections (less than 0.032") and gas metal arc welding is used for heavier sections. Use alloy 4043 filler wire for best results, although a decrease in T 6 properties will result.


    Heat Treatment Solution heat treat at 990 F for adequate time to allow for thorough heating and then water quench. Precipitation hardening is done at 320 F for 18 hours and air cool, followed by 350 F for 8 hours and air cooling.


    Forging The alloy is capable of being hot forged at temperatures in the range of 900 F to 750 F.


    Hot Working Hot working may be done in the temperature range of 700 F to 500 F.


    Cold Working Cold working in the O temper condition is readily performed. The alloy is notably less easy to cold form in the T 4 and T 6 tempers.


    Annealing Annealing should be done at 775 F for 2 to 3 hours followed by controlled cooling at 50 f per hour down to 500 F, then air cool.


    Aging The aging precipitation heat treatment is done at 350 F for 8 hours followed by air cooling. This produces the T6 temper.


    Tempering Not applicable.


    Hardening See "Aging".


    Other Physical Props Electrical conductivity 40% of copper.


    Other Mechanical Props Shear strength for O temper is 12 ksi and for T 6 temper it is 30, ksi

    The 5052 is not as strong but deals better with vibration. If there is any welding on the plate the 5052 will end up much stronger as 6061 loses a lot of strength when heated.

    5052 is a good strong alloy that can deal with a lot and I would be surprised if you had any problems.
