I was too busy at work today to call Mororso myself.

Does anyone know the type of aluminum used for Moroso's Honda oil pans? I have an H22 pan that I need to add some baffles to in order to use it for a road racing application. I'd like to pick the same alloy, if at all possible.

Thanks!

 

id says it is 6061 since it is a weldable alloy

 

Yes, I agree about the 6061. You can weld it fine with 4043. If you're a stickler for strength, go with 5356...but it doesn't weld quite as well..and you really won't need that.

 

it's going to be either 3003 or maybe 5052 at hamburgers we used 3003 both weld with 4043 filler wire 6061 is not a good alloy for a pan and would tend to crack allot due the vibrations within the pan plus its to hard to work with when bending and the cost is higher 5052 is a great alloy for body panels and it welds really well 3003 is softer and easier to work with

The alloy used is most likely 6061. It would probably start out in an O condition for formability. Then it would be welded. Finally, it gets heat treated to a T6 condition for strength. Since you must heat treat 6061 after welding anyway, using an O condition to start out with allows small radius bends without cracking the material.

 

Good points guys...I wasn't thinking much about 6061 being a bit more prone to cracking when bending.

I still think I'd go with 4043 weld wire though.

 

Engloid I agree and no matter what it is made of 4043 is the correct filler rod.

? building a pan in O and heat treating it afterwards I thought we were talking about a relatively inexpensive oil pan and not space shuttle parts The pan rails are normally made of 6061 -t6 but the rest is usually 3003 which is very easy to work and tolerates the vibrations well
