Aluminum strip sheets are widely used as air cooling fin materials for tubes. These high-quality aluminum products are designed to meet the needs of various industries, especially in heat exchanger manufacturing. They are ideal for use in fin mills due to their excellent consistency and performance.
- **Good consistency for any fin mill**
- **Excellent mechanical properties and surface condition**
**Aluminum Brazing Material Production**
Aluminum brazing is a key process in joining components in heat exchangers. This method uses a near-eutectic Al-Si filler alloy that melts at approximately 50°C lower than the core material. This allows complex assemblies to be joined into a single unit with just one pass through a brazing furnace.
**Compound Material**
The aluminum brazing material is a multi-layer compound consisting of a core alloy that provides strength and durability, and a clad brazing filler. A protective layer can also be added on one side to prevent corrosion on the water side of radiators.
During the brazing process, only the clad filler melts, while the core remains solid. The design and materials are carefully selected to ensure optimal mechanical properties and corrosion resistance after brazing.
**Roll Cladding**
Roll cladding is a common industrial technique used to join similar or dissimilar aluminum alloys. It's widely used in aerospace, automotive, and heat exchanger applications. The process involves hot rolling to create a metallurgical bond between the core and cladding layers.
Another technique is cast cladding, which allows multiple metal streams to be cast into a single ingot using modified direct chill molds.
**Cladding Thickness**
Signi Aluminium has an established roll bonding process that ensures tight cladding thickness tolerances, essential for consistent brazing results. Thin clads of 5% and thicker clads of 20% are available, depending on the application requirements.
