which materials are reliable for upright & hub manufacturing ?

RE: automotive

Almost every car I worked on over the years had forged steel knuckles and cast iron hubs. Some of the uprights may have been cast steel, or maybe cast iron with a steel stub axle, but I rarely work on cars newer than about 10 years old.

RE: automotive

I'm guessing "cast iron" knuckles, spindles, etc are nodular iron or even cast steel to bring some ductility to the party.

RE: automotive

If they are ferrous castings, they are nodular iron, aka ductile iron. Gray iron lacks sufficient strength and impact resistance. Steel is not castable in such intricate sections. You will not find a steel casting in an automobile.

RE: automotive

thank u all guys...but my upright is withstand more than 300 kg weight, what type of compositions we have to use,titanium coated steel is possible or not ?

RE: automotive

300 kg is very light corner weight for a car. Titanium won't help you much, and is a ridiculous suggestion, cost wise.

If this is for a cheap production car use cast nodular iron, if weight is an issue and you have agood vendor then forged aluminium.

If it is for a one off I suggest welded steel.
