Ductile Iron Exhaust Manifolds, product photos Advantages of ductile iron exhaust manifolds: 1. High tensile strength and elongation, so strong enough for tough working condition. Disadvantages of ductile iron exhaust manifolds: 1. High production costs, so caused high product prices, about 5% to 10% higher than gray iron manifolds. 2. More casting defects, so caused high defective rate, difficult for foundry production.
