Custom Iron Castings for Industrial Applications
Iron Casting
Iron casting is where G&W Foundry began in 1932, and it remains at the core of what we do today. We produce high-quality grey and ductile iron castings designed for durability, precision, and long-term performance in demanding applications.
Engineered for strength, wear resistance, and machinability
Custom iron grades tailored to your exact requirements
From prototype to full-scale production
Why Iron Casting?
Cast iron continues to be one of the most trusted materials in modern manufacturing due to its versatility and performance.
- High strength and durability
Built to withstand heavy loads and long-term use - Excellent wear resistance
Ideal for high-friction and industrial environments - Superior machinability
Reduces downstream processing time and cost - Cost-effective alternative to steel
Especially with ductile iron in structural applications
Grey Iron vs. Ductile Iron
We specialize in both primary types of iron casting and help you select the right material based on your application.
Grey Iron
Best known for vibration damping and thermal conductivity
- Ideal for:
- Engine blocks
- Machine bases
- Brake components
- Common grades: Class 30, 40, 60
Ductile Iron
Engineered for strength and flexibility
- Higher tensile strength and impact resistance
- Can replace steel in many applications
- Common grades: 65-45-12 and similar
Not sure which material is right? We’ll guide you based on your performance and cost requirements.
