Production process of 6012 aluminum bars
Drawing process
6012 aluminum rods are produced using an advanced drawing process, ensuring product accuracy and consistency, especially suitable for applications requiring high precision.
Drawn rods are cold-processed to increase strength and have a smooth surface quality, reducing the need for further processing.
Extrusion process
Extrusion is one of the main processing methods for 6012 aluminum rods. Aluminum rods produced through hot extrusion have good mechanical properties and stable structures.
The process is cost-effective and fast, making it ideal for large-scale production.
Heat Treatment Process
To further improve the mechanical properties of 6012 aluminum rods, strict heat treatment processes are applied, including solution treatment, quenching, and aging.
These processes ensure that the tensile strength and yield strength of the rods meet design requirements while enhancing their corrosion resistance and ductility.
Anodizing of 6012 aluminum bars
The surface of 6012 aluminum rods can undergo anodizing treatment to increase corrosion resistance and improve appearance, making them particularly suitable for end products requiring a high aesthetic quality.
Brazing process of 6012 aluminum bars
6012 aluminum alloy has good brazing performance. We recommend using specialized aluminum-based brazing materials to ensure the quality and effectiveness of the brazing process.
Comparison with other easily machinable lead alloys
6262 has inferior environmental characteristics compared to 6012 due to its higher lead content, limiting its use in certain applications.
2011 Aluminum Alloy, known as a "free-cutting alloy," performs excellently in machining due to its high lead content, making it ideal for high-precision turning. However, its higher lead content restricts its environmental suitability.
6042 Aluminum Alloy is an improved version of 6262, with lower lead content and good machinability, meeting RoHS standards. However, compared to 6012, 6042 is limited by its higher price.
