The scrap price for engine block is determined by the material composition, weight, and current market demand for scrap metal. Engine blocks are primarily made from either cast iron or aluminum, with aluminum engine blocks generally fetching a higher price due to the material’s value and lightweight nature. Scrap yards price engine blocks based on weight, and prices can fluctuate based on local scrap metal values and the quality of the materials. A clean, oil-free engine block will often receive a higher payout. Recycling old engine blocks not only provides financial benefits but also contributes to sustainable resource management, as the metals can be repurposed in new manufacturing processes.
