Aluminum Annealing Furnace: Precision Heat Treatment Solution for Aluminum Products

In the aluminum processing industry, achieving the right mechanical properties and dimensional stability is critical. Whether manufacturing aluminum sheets, coils, extrusions, or castings, the heat treatment process plays a central role in determining product quality. One of the most essential processes is annealing, and the best way to achieve controlled and uniform annealing is through a dedicated aluminum annealing furnace.

As a professional aluminum heat treatment equipment manufacturer, we provide customized aluminum annealing furnaces for global clients across manufacturing, automotive, aerospace, and construction sectors. This article introduces our aluminum annealing furnace product line and outlines its features, technical specifications, and key benefits.

What Is an Aluminum Annealing Furnace?

An aluminum annealing furnace is a type of industrial heat treatment equipment used to soften aluminum after cold working processes such as rolling, extrusion, drawing, or stamping. The process improves ductility, relieves internal stress, and enhances machinability.

Annealing is typically carried out at temperatures ranging from 300°C to 500°C, depending on the aluminum alloy and product thickness. A high-quality furnace ensures uniform temperature distribution, atmosphere control, and energy efficiency, which are critical for producing consistent aluminum parts.

Applications of Aluminum Annealing Furnace

Our aluminum annealing furnaces are widely used in the following applications:

Aluminum Sheet and Coil Processing

Aluminum Extrusion Profiles

Aluminum Foil Production
