Products » Aluminum Solution Heat Treating
Aluminum solution treating is commonly conducted in molten nitrate baths in the 850-1050 deg F range. Maintenance of neutrality to avoid attack on aluminum is critical. Heatbath®/Park Metallurgical nitrate salts are formulated for maximum purity and neutrality for use in aluminum solution treating.
