PHI Non-Ferrous Flux
Cleaner Melt. Lower Metal Loss. Better Casting Quality.
The quality of an aluminum casting starts with the quality of the molten metal.
During melting, holding and transfer, molten aluminum can form oxides, inclusions and dross that may affect casting quality and increase metal loss. Proper aluminum melt treatment helps improve melt cleanliness, control metallurgy and recover more usable aluminum from the process.
Prolific provides a comprehensive range of aluminum fluxes and melt-treatment products for foundries, die casters and aluminum processors, covering:
Melt cleaning and skimming
Dross treatment and metal recovery
Reduction of oxide and metallurgical impurities
Sodium modification
Grain refinement
Primary silicon refinement
Improvement of feeding and solidification behavior
Release agents and coatings
Our solutions can be selected according to the aluminum alloy, casting process, furnace type and required metallurgical result.
Why Is Aluminum Melt Treatment Important?
Aluminum is widely used for lightweight, high-performance components in industries such as automotive, transportation, electronics, machinery and general engineering. However, achieving consistent casting quality requires more than simply melting the alloy. Proper melt treatment can help:
Improve Melt Cleanliness
Remove or separate oxides and non-metallic inclusions from molten aluminum.
Reduce Metal Loss in Dross
Promote better separation between aluminum and oxide-containing dross so that more usable metal can be recovered.
Improve Casting Properties
Appropriate modification and grain refinement can improve the microstructure and mechanical properties of the final casting.
Control Solidification
Grain refiners, modifiers and feeding aids can help control solidification behavior and reduce casting defects.
Improve Process Stability
Selecting the correct treatment for the alloy and casting process helps achieve more consistent production quality.
Aluminum Melt Treatment by Function
Different foundry processes require different metallurgical treatments. Rather than using one universal flux, the treatment should be selected according to its intended function.

Choosing the Correct Aluminum Flux
There is no single aluminum flux suitable for every foundry application. The correct melt-treatment product depends on several factors:
Casting process
Pressure die casting, gravity die casting, sand casting or continuous casting.
Alloy composition
Hypoeutectic AlSi, hypereutectic AlSi, AlMg, AlCu, AlZn or other aluminum alloys.
Treatment objective
Cleaning, skimming, dross treatment, modification, grain refinement, primary silicon refinement or feeding control.
Furnace and processing method
Crucible furnace, holding furnace, melting furnace, dosing furnace or centralized melting system.
Application method
Manual treatment, plunging, impeller treatment or automatic dosing.
Selecting the correct product and dosage is important to obtain the desired metallurgical result while avoiding unnecessary chemical consumption.
