HYSCAN II - Hydrogen Analysis in Molten Aluminum
The Only One of Its Kind in the World
.
The presence of hydrogen in molten aluminum creates significant challenges for casting and foundry industries, since high residual hydrogen content can lead to severe porosity after solidification, resulting in rejected parts or the risk of mechanical failure.
.
The H-Scan system enables a substantial improvement in both the quality and reliability of aluminum castings by allowing precise control of hydrogen content in molten aluminum just before casting. No over- or under-degassing. No rejects. No wasted time or money.
🔹 General Description
- The H-Scan II is a molten aluminum hydrogen analyzer based on the Reduced Pressure Test (RPT) method.
- It is designed to measure dissolved hydrogen gas in liquid aluminum to prevent porosity defects in cast products.
- This is a widely used industrial reference system in foundries, recycling plants, and aluminum alloy production facilities.
Operating Principle
- A sample of molten aluminum is taken and placed in a sealed chamber
- The system reduces pressure inside the chamber
- Dissolved hydrogen is released during solidification
- The instrument measures the released gas volume
- Results are expressed as cm³ of H₂ per 100 g of metal
- Full analysis is completed in under 5 minutes

¿Qué es Análisis de Hidrógeno en Aluminio Fundido? El análisis de hidrógeno en aluminio fundido es un procedimiento metalúrgico que permite medir la cantidad de gas hidrógeno disuelto en el aluminio líquido antes de que se solidifique.
¿Por qué es importante medir el hidrógeno? El hidrógeno es el único gas que se disuelve significativamente en el aluminio líquido.
Cuando el metal se enfría y solidifica, el hidrógeno ya no puede permanecer disuelto, y forma burbujas microscópicas dentro de la pieza. Estas burbujas provocan porosidad interna, lo que reduce la resistencia mecánica, la estanqueidad y la calidad superficial de las piezas fundidas. Por eso, conocer la cantidad de hidrógeno presente en el baño metálico es fundamental para asegurar la calidad final del producto.
