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