Sodium Hydroxide / Caustic Soda 15 %
The 15% sodium hydroxide serves as an effective macro-etching agent for aluminum welds, including those made of aluminum alloys, pure aluminum and hard aluminum alloys.
Due to its strong alkaline properties, the caustic solution can effectively attack the surface of aluminum welds, resulting in a high-contrast visualization of the individual weld layers and heat-affected zones. This macroscopic weld assessment is critical for quality assurance and process control in manufacturing.
Chemically, sodium hydroxide is a strong base that forms an alkaline solution when dissolved in water. This alkaline nature results in an effective etching reaction when in contact with aluminum.
When applied to aluminum welds, the sodium hydroxide reacts with the surface, causing an etching reaction. This results in a visually differentiated appearance of the weld layers and heat affected zones, allowing a detailed assessment of the weld quality.
