'82 seca wheel alloy composition?????

i need to make a new thread to get some visibility for my question.

does anyone KNOW what material/composition the wheels are? i want to cut it up and tig it back together. for good results it would be good to use filler of the same material.

also if someone would have a clue of where to ask, please share


thanks

 

maybe take the wheel, or shavings from it once you cut it to a local metal recycler. They'll know, or know who would, since their paid differently for different alloys.

 

They are cast aluminum; that's all I know for sure.

 

haha, that is a very good idea

i agree with you bigfiz, theyre aluminum, but i bet theyre some sort of alloy and id really like to know which.. does anyone know yamahas email address ?

 

Probably got some magnesium in there.

 

If you need filler that is the same material, would it not be logical to just get some material from a damaged wheel? Bound to be a few around.

 

Yamaha didn't make the wheels. They were made by a company formerly known as Asahi Malleable Iron (look carefully it's cast into some of them) now known as Asahi Tec. They appear to be a Tier 1 OEM supplier to both the automotive and motorcycle industries. https://www.asahitec.co.jp/english/product/wheel.html If anybody would know the type of aluminum alloy used, they might.

 

yes my wheels say asahi also why did i forget that.. thanks for the link bigfitz! i already approached them with an email, see if they answer

 

well would you have guessed, no answer.

 

Venlis in all honesty as long as you use an alloy that is close to the same composition as the wheel you will be more then ok. The heat generated by tig, mig, stick, whatever type of welding you use will alter the composition of the metal slightly. Not to mention that the metals will actually flow into each other thus mixing to a very simmilar alloy. Also some wheels will (on a rare occasion) have an alloy code stamped on them. Another somewhat shure fire way to find out what a wheel is made of is to look back and see what was ecconomicaly feasible during the era the wheel was manufactured in. If you are that worried about it though do what one member suggested. Find a junk wheel and use it for donor material.

 

Venlis i have a little more input on your question. I just got back from doing some work in a aluminum component casting plant. they would melt 1000+ pound aluminum plates, as well as aluminum wheels purchased from scrap yards and make automotive parts from them. As far as i could tell no further chemicals were added to the molten alloy. And the parts were used for transmision, suspension, and engine components. My guess would be that the alloy used in our wheels is more then likely the same as the wheels melted. So in all honesty any donor aluminum you can find that was useed in a wheel would work for you. My only suggestion is that the surface you weld and the donor material be clean and contaminant free as that will effect the weld quality.

 

great stuff mechanicalmadness, and welcome
