Degasser for Aluminium

Foundry Chemicals

A degasser for aluminium is a vital solution used in aluminium melting and casting operations to remove dissolved hydrogen and unwanted gases from molten metal. As aluminium production expands across automotive, construction, electrical, packaging, and engineering industries, the demand for high-quality, defect-free aluminium has increased significantly. Degassing plays a crucial role in achieving this quality.

For aluminium manufacturers in India and international markets, using a reliable aluminium degasser improves metal cleanliness, enhances mechanical properties, and reduces rejection rates. Degassers are essential for foundries, extrusion plants, rolling mills, and recycling units aiming to meet global quality standards.

What Is a Degasser for Aluminium

A degasser for aluminium is a chemical or flux-based product introduced into molten aluminium to remove dissolved hydrogen gas and non-metallic impurities. Hydrogen is the most common gas absorbed by molten aluminium and is a primary cause of porosity and internal defects in cast products.

Aluminium degassers react with hydrogen and other gases, allowing them to escape from the molten metal. This process results in cleaner aluminium with improved density, surface finish, and structural integrity.

Importance of Degassing in Aluminium Processing

During melting, aluminium easily absorbs hydrogen from moisture, fluxes, and the surrounding atmosphere. If this hydrogen is not removed before casting, it forms gas porosity during solidification, leading to weak and defective components.

Degassing is therefore essential to ensure high-quality aluminium production. By using an effective degasser, manufacturers can achieve better casting soundness, improved mechanical strength, and consistent performance in finished aluminium products.

How Aluminium Degasser Works

When a degasser is added to molten aluminium, it releases active compounds that react with dissolved hydrogen and other gases. These gases are then transported to the surface of the melt and released into the atmosphere.

This controlled gas removal process reduces internal porosity, improves metal homogeneity, and prepares the aluminium for further treatments such as grain refining and filtration. The result is a clean and stable melt suitable for high-precision applications.

Types of Degasser for Aluminium

Solid Aluminium Degassing Tablets

Solid degassing tablets are widely used in aluminium foundries due to their ease of handling and consistent performance. These tablets are plunged into molten aluminium, where they react efficiently to remove hydrogen and impurities.

Granular Aluminium Degasser

Granular degassers are added directly to the molten metal surface or injected into the melt. They are suitable for both primary and secondary aluminium processing and offer flexibility in dosing.

Rotary Degassing Flux

Rotary degassing systems use flux-based degassers combined with inert gas injection to achieve deep and uniform hydrogen removal. This method is commonly used in high-volume and high-quality aluminium production.

Applications of Degasser for Aluminium

Aluminium degassers are used in a wide range of applications, including aluminium casting, extrusion billet production, rolling slabs, die casting, and recycled aluminium processing.

They are essential in industries such as automotive components, electrical conductors, aerospace parts, cookware manufacturing, construction profiles, and industrial machinery. In India, aluminium degassers are widely used in Gujarat, Maharashtra, Tamil Nadu, Karnataka, Odisha, Haryana, and Delhi NCR. International demand is strong in the Middle East, Southeast Asia, Africa, Europe, and North America.

Manufacturing Process of Aluminium Degasser

The manufacturing process of a degasser for aluminium begins with the selection of high-quality raw materials and active compounds. These materials are carefully formulated to ensure controlled reaction rates and consistent degassing efficiency.

The mixture is processed into tablets, granules, or powder form under strict quality control. Each batch is tested to ensure hydrogen removal efficiency, stability, and compatibility with various aluminium alloys.

Quality Standards and Performance Expectations

A high-quality aluminium degasser should offer rapid hydrogen removal, low residue formation, and minimal impact on metal chemistry. It should work effectively at different melt temperatures and alloy compositions.

Manufacturers supplying international markets focus on consistent performance, low fume generation, and compliance with global metallurgical and environmental standards.
