On the other hand, the reason I have avoided choosing stainless steel, iron, steel and wood over cast aluminum as the frame is that stainless steel is expensive and when creating stainless steel without the highest technology machine which is good. For this reason, the stainless steel is high cost, maintaining the machine will be costing money compared to cast aluminum which is casting. Also, stainless steel can be hard to handle meaning the material all be having a large amount of waste and re-work. Stainless is heard to welding because of its fast dissipation of heat which can create ruined pieces or even high scrap cost.
